25 Powerful Ways to Boost the Mitochondria in Your Brain

Picture of several mitochondria.

It’s becoming increasingly clear that chronic mitochondria dysfunction is one of the main underlying factors that contributes to poor brain function and mental illness. 

Mitochondria are unique structures within every cell of your body. You have trillions and trillions of them, making up approximately 10% of your total body weight.

Mitochondria are considered the “powerhouses of the cell,” generating most of the energy in your body by converting nutrition into adenosine-5’- triphosphate (ATP). ATP is your body’s main source of cellular fuel. You are constantly using it, and your brain needs enough of it to work properly (106-107). 

Your mitochondria are critically important and need to be supported to overcome depression and anxiety, and reach optimal brain and mental health.

Mitochondria are especially abundant in your brain cells and involved in many important biological processes in the brain, including the regulation of free radicals and neurotransmitters.

In fact, monoamine oxidase (MAO), the enzyme responsible for the metabolism of monoamine neurotransmitters, is localized within the outer mitochondrial membrane (91-93). 

So not surprisingly, numerous studies show that there is a correlation between impaired mitochondrial function in the brain and many psychiatric and neurodegenerative diseases, including:

In fact, some researchers are convinced that mitochondrial dysfunction is involved in almost every chronic disease (108-110). 

Mitochondria dysfunction decreases ATP energy production and increases oxidative stress, which are commonly found in the brains of people suffering from brain and mental health disorders.

Cognitive symptoms of mitochondrial dysfunction can also include impairments in attention, executive function and memory (105).

Unfortunately, a number of psychiatric drugs damage the mitochondria and worsen the dysfunction.

But luckily, there are ways to halt and reverse mitochondrial decay.

Below are a number of strategies I’ve used over the years to support my mitochondria.

Supplements and lifestyle changes can improve mitochondrial health by increasing the availability of proteins needed for ATP production.

They also act as antioxidants, assisting the mitochondria in reducing oxidative stress.

Some of the following lifestyle changes and supplements can also increase the number of mitochondria present within the cell.

And you can start using them today to regain optimal brain and mental health.

 

1. Eat Nutrient-Dense, Whole Foods

Dr. Terry Wahls standing in front of her wheelchair.

Eating lots of fresh, nutrient-dense whole foods is an impactful action you can take to power your mitochondria. 

In order to thrive, your mitochondria need phytonutrients, antioxidants, healthy fats and proteins.

Dr. Terry Wahls, MD, clinical professor of medicine at the University of Iowa, is a leading expert on the relationship between nutrition and mitochondrial health.

She was diagnosed with multiple sclerosis (MS) more than a decade ago but reversed the neurodegenerative brain disease by repairing her mitochondria with an intensive nutritional strategy.

She outlines how she recovered her health in her book The Wahls Protocol

Research on her protocol shows that patients witness a “significant improvement in fatigue” (67). 

She recommends eating six to nine cups of vegetables and fruits every day, including green veggies (kale, spinach), brightly colored vegetables (beets, carrots, peppers), and sulfur-rich veggies (broccoli, cauliflower).

My Free Grocery Shopping Guide for Optimal Brain Health contains a bunch of foods that you should be eating on a regular basis for optimal mitochondrial health. 

Dr. Wahls also has a fascinating TED talk that you can watch if you're interested in learning more. 

 

2. Limit Certain Foods and Ingredients

Pizza, burgers and fries. Fast, processed food impairs mitochondria health.

Eating poor-quality foods can also wear down your mitochondria. 

Your mitochondria were not designed to deal with our current food environment and lifestyle habits. 

That’s why you should limit refined sugars, processed flours, industrial oils and trans fats. They can damage your mitochondria and prevent them from properly producing energy.

Dr. Wahls also recommends you avoid all gluten, dairy and soy products for optimal mitochondrial health.

I used to strictly avoid all of these foods and I felt better when I did, but no longer need to since restoring my health.

 

3. Eat More Essential Fats

Healthy fats, including omega-3 fatty acids, help build and strengthen the membranes of your mitochondria. They’ve also been shown to improve mitochondrial function in the brain (5-7). 

That’s why Dr. Wahls recommends eating organic grass-fed beef or wild-caught fish, such as salmon, every day.

Avocados, nuts, seeds, coconut and olive oil are also rich in healthy fats. 

Supplementing with krill oil is another excellent option.

 

4. Exercise

Not surprisingly, exercise strengthens your mitochondria by increasing oxygen and blood flow and activating biochemical pathways that produce new mitochondria (8). 

Runners have more high-functioning mitochondria than non-runners, and strength training and high-intensity interval training also increase the number of mitochondria and improve the efficiency of your existing mitochondria (9, 10).

Exercise can also increase brain-derived neurotrophic factor (BDNF).

 

5. Low-Level Laser Therapy (LLLT)

Low-level laser therapy (LLLT) is a treatment that uses low-level (low-power) lasers or light-emitting diodes (LEDs) to stimulate brain cells, helping them heal and function better. 

There is strong evidence to suggest that LLLT supports the mitochondria. 

Research shows that LLLT reduces oxidative stress and increases the production of ATP energy in mitochondria (39, 40). 

These mitochondrial benefits have also been seen directly within the brain.

Studies show that LLLT increases mitochondrial activity within brain cells, and this leads to beneficial effects in behaviour (41). 

LLLT treatment has also been shown to increase the number of mitochondria, and mitochondrial oxygen usage, within the brain (42, 43).

I have used these two LLLT devices myself at home to support my mitochondria and boost my brain function:

  • Optimal 1000 Brain Photobiomodulation Therapy Light (Combo Red/NIR) - This is a powerful device that shines 660 nm of red light and 850 nm of infrared light. You can shine it on your forehead for 5 minutes every day. You can also shine it on other parts of your head and on your entire body, including your thyroid, thymus gland and gut.

  • Vielight Neuro Duo – This is a transcranial-intranasal headset with 810 nm of near infrared light. It penetrates deeper into brain tissue and is absorbed better by the central nervous system. If you decide to get this one, you can use the coupon code JORDANFALLIS for a 10% discount. Some research has shown a 20-fold higher efficiency of light delivery to the deep brain through the nose instead of transcranial application (125).

You can learn more about LLLT in this post

You should also limit your exposure to artificial blue light, as excessive blue light exposure can also wear down your mitochondria. You can learn more about the risks of too much blue light in this post

6. Resveratrol

Resveratrol is a beneficial antioxidant compound found in grapes and red wine. 

Not only does it increase BDNF levels, but it also activates the SIRT1 gene. This gene triggers a number of positive biochemical reactions that protect and improve the functioning of your mitochondria. Caloric restriction and intermittent fasting also trigger the SIRT1 gene (11-13).

In 2006, Harvard researchers found that resveratrol increases lifespan by protecting the mitochondria (14).

Resveratrol is included in the Optimal Energy supplement.

 

7. Caloric Restriction and Intermittent Fasting

Restricting your calories is one the best actions you can take to improve mitochondrial function.

Studies show that eating less food reduces the demand and damage on your mitochondria. 

But reducing calories is tough to do and absolutely no fun. 

So you can do intermittent fasting instead. 

Fasting activates your mitochondria and triggers autophagy, which is an intracellular process that essentially allows your mitochondria to clean themselves by removing unwanted and damaged debris, proteins and reactive oxygen species (1, 2, 4).

This process has been shown to reduce the risk of cancer, Parkinson’s disease and Alzheimer’s disease (3). 

 

8. Nicotinamide Adenine Dinucleotide (NADH)

NADH is a naturally-occurring compound found in the cells of all living organisms.

It plays a key role in the production of energy within the cell and is highly concentrated within your mitochondria (45). 

Depletion of NADH has been linked to a number of diseases, including depression, chronic fatigue syndrome, Alzheimer’s and Parkinson’s.

But stabilized oral NADH has been shown to improve all of these conditions (46, 47, 48). 

Although I don’t take it anymore, I’ve witnessed a beneficial effect from supplementing with NADH.

LLLT is also known to increase NADH in your mitochondria. 

Check out this article for other ways to increase NAD.

 

9. Ketogenic Dieting

A ketogenic diet is a very low-carb diet. 

When you restrict carbohydrate-rich foods, your body enters ketosis.

Ketosis is a metabolic state in which your body and brain run on fatty acids and “ketones” instead of glucose (36).

Ketones are an alternative source of energy for your brain cells and they support your mitochondria. 

When your mitochondria are dysfunctional, following a ketogenic diet can be an effective strategy to fuel the mitochondria. 

When mitochondria are fueled by ketones instead of glucose, their ability to produce ATP is enhanced and free-radical byproducts are reduced.
— Dr. Jong Rho, MD, Professor of Pediatrics and Clinical Neurology at the Alberta Children’s Hospital

Ketogenic diets may help treat many different brain and mental health diseases including Alzheimer’s, Parkinson’s, epilepsy and autism. 

Exogenous ketones can also help you get into ketosis and experience the mitochondrial-boosting effects of ketones very quickly.

 

10. B Vitamins

B vitamins play an essential role in maintaining mitochondrial function.

In fact, your mitochondria will be compromised if you have a deficiency of any B vitamin (37). 

Deficiency is more likely if you take certain medications

Vitamin B1, B2, B3, B5, B6 and B12 are all included in the Optimal Energy supplement for this reason.

11. Ribose

Ribose is a five carbon sugar created naturally by your body.

Even though it’s a sugar, research suggests it does not raise blood sugar levels.

Instead, your body stores it in the mitochondria (49, 50). 

Ribose is used by the mitochondria to produce ATP and if you don’t have enough, you’ll experience low energy (51). 

Chronic stress can deplete ribose, and certain conditions have been linked to chronic ribose deficiency, including depression and chronic fatigue syndrome.

People can supplement with ribose if they struggle with these disorders because it can help reduce mental and physical lethargy (52, 53).

Ribose is also included in Optimal Energy.

 

12. Coenzyme Q10 (CoQ10)

Coenzyme Q10 (CoQ10) is an antioxidant molecule found in every cell of your body.

It’s particularly concentrated in the mitochondria, playing a key role in the production of energy.

It also protects the mitochondria from oxidative damage. 

Without CoQ10, your body cannot synthesize ATP because CoQ10 is an essential component of the mitochondrial electron transport chain.

Many doctors are unaware that CoQ10 is an excellent treatment for many brain health issues, including depression, chronic fatigue syndrome, and Alzheimer’s disease

Low levels of CoQ10 can cause brain fog, mental fatigue, difficulty concentrating, memory lapses, depression and irritability (68-70). 

Researchers have found that CoQ10 levels are significantly lower in the depressed patients (71). 

Unfortunately, chronic oxidative stress and medications can further deplete CoQ10

But supplementing with CoQ10 can increase your mitochondrial energy production and reduce symptoms of depression and chronic fatigue (71). 

Food sources with high natural concentrations of CoQ10 include organic red palm oil and grass-fed beef heart (72, 73). 

But supplementing with it will give you a more significant mitochondrial boost.

 

13. Pyrroloquinoline quinone (PQQ)

Pyrroloquinoline quinone (PQQ) is a vitamin-like enzyme and potent antioxidant found in plant foods.

It has a wide range of brain health and mitochondrial benefits.

It’s been shown to preserve and enhance memory, attention, and cognition by protecting the mitochondria from oxidative damage.

It also promotes the growth of new mitochondria in the brain (56-59). 

Since it helps grow new mitochondria, it may help you if you suffer from depression, since fewer mitochondria have been found in people with depression (63). 

Reactive nitrogen species (RNS) and reactive oxygen species (ROS) cause severe stress on brain cells and mitochondria.

PQQ has also been shown to suppress RNS and ROS (60-62). 

Researchers have also found that supplemental PQQ can be neuroprotective by increasing mitochondrial activity levels (64-66). 

I personally never really noticed much of anything from PQQ. So I don’t take it anymore and didn’t include it in Optimal Energy.

 

14. Magnesium

Magnesium is a vital mineral within your body.

Mitochondria are considered magnesium “storage units” because they hold onto a lot of your body’s magnesium. 

Magnesium also protects the mitochondria and plays a role in the production and transfer of ATP within the mitochondria.

And research shows that if you have a deficiency in magnesium, your brain cells will have fewer mitochondria, and they will be less healthy (54, 55). 

This is just another reason to supplement with magnesium every day.

 
Scientific representation of brain and brain blood flow.

Carnitine is an amino acid that improves mitochondrial activity and plays an important role in energy production.

It’s known to transport fatty acids directly into the mitochondria of your brain cells. 

It’s also required to produce ATP and deficiencies are associated with reduced mitochondrial function in the brain (74). 

Supplementing with carnitine makes it easier for fatty acids to cross your blood-brain barrier and nourish the mitochondria within your brain. This can improve your mood, memory and energy levels.

Several studies show that carnitine eases depressive symptoms and improves quality of life in patients with chronic depression (75-78). 

And individuals with autism often have reduced levels of carnitine within their brain (79). 

Carnitine is synergistic with Alpha Lipoic Acid (ALA), meaning that when you take them together, they are more effective at supporting the mitochondria in your brain.

ALA is a mitochondrial enzyme and antioxidant. It is fat soluble and can easily cross your blood-brain barrier.

It’s been shown to improve cognition by reducing oxidative stress in the brain.

It also protects existing mitochondria and creates new mitochondria in the brain (80, 101).

Both ALA and carnitine are included together in Optimal Energy.

16. Thiamine

Thiamine, also known as Vitamin B1, is an essential water-soluble nutrient that cannot be made by the body.

It’s used in nearly every cell in the body and it’s especially important for supporting energy levels and mitochondrial functioning in the brain.

It’s also required by nerve cells and other supporting cells in the nervous system.

Research shows that thiamine deficiency induces oxidative stress, resulting in mitochondrial abnormalities in the brain (21-22).

Healthy food sources of thiamine include green peas, beef liver, asparagus, pecans, spinach, sunflower seeds, macadamia nuts, oranges, cantaloupe and eggs. 

These foods are included in my Free Grocery Shopping Guide for Optimal Mental Health.

Thiamine is also included in Optimal Energy.

 

17. Creatine

Creatine is a molecule produced in the body and found in foods, particularly meat, eggs, and fish.  

Creatine is also available as a supplement.

Athletes, bodybuilders, wrestlers, sprinters often take extra creatine to gain more muscle mass.

It’s an incredibly well-researched supplement and safe to take regularly. 

Supplementing with creatine can also support the brain.

It's been shown to have neuroprotective effects. It rapidly produces energy to support brain cell function.

Researchers have also found that creatine supplementation improves function of mitochondria in the brain (25).

 

18. Curcumin

Curcumin is the most heavily researched compound within turmeric, the spice that gives curry its yellow colour.

Curcumin protects mitochondria and prevents mitochondrial dysfunction in the brain (111-113).

Curcumin can be found in both Optimal Energy and Optimal Antiox.

 

19. Malic Acid

Malic acid, also known as malate, is an intermediate of the Krebs cycle.

It’s a key step in the pathway of energy production by the mitochondria.

And it has a number of health benefits because it improves mitochondrial function.

Malate supplementation has been shown to increase the availability of NAD+, which is necessary for producing ATP.

Malate also increases NADPH levels, which is a fundamental antioxidant in the body that promotes mitochondrial function (114).

That’s why I’ve included malic acid in the Optimal Energy supplement.

 

20. Niacinamide

Niacinamide, also known as nicotinamide, is a vitamin found in foods.

It’s also often taken as a supplement.

Niacinamide is the precursor to NAD+ and therefore supplementation can increase levels of this molecule and improve mitochondrial function.

Researchers have found that niacinamide prevents energy depletion in the brain (115).

It also improves the mitochondrial quality of brain cells by inducing autophagy and causing dysfunctional mitochondria to fragment (116).

21. N-Acetyl-Cysteine

N-Acetyl-Cysteine (NAC) is a modified form of the amino acid cysteine.

It’s also the precursor to glutathione, your body’s master antioxidant.

Nowadays, we’re exposed to so many environmental toxins, which cause oxidative stress in the body and deplete our reserves of cysteine and glutathione.  

But supplementing with NAC can increase and normalize your cysteine and glutathione levels. 

This can combat and reduce oxidative stress in your brain, which can then help treat several mental illnesses.

NAC can also help support your mitochondria.

In one study, NAC treatment for 9 weeks reduced oxidative damage to the mitochondria (117).

And in multiple cell studies, NAC improved mitochondrial function by reducing oxidative stress (118-119).

 

22. Succinic acid

Succinic acid, also known as succinate, is an intermediate molecule of the Krebs cycle that plays a significant role in the electron transport chain.

It can be purchased as a supplement to boost energy production by the mitochondria.

Succinic acid has been shown to prevent structural and functional damage to the mitochondria caused by oxidative stress (120).

And in brain cells that have mitochondrial dysfunction, succinic acid supplementation improved mitochondrial functioning by increasing glucose and oxygen usage. This led to increased levels of ATP energy (121).

For this reason, succinic acid is in the Optimal Energy supplement.

 

23. EGCG

Epigallocatechin-3-Gallate (EGCG) is the main polyphenol found in green tea.

It’s been shown to have anti-inflammatory and neuroprotective effects.

EGCG accumulates within the mitochondria and activates a number of proteins related to mitochondrial function (122-124).

I personally drink organic green tea regularly, usually in place of coffee on days when I’m relaxing.

However, it’s important to keep in mind that the body isn't very good at absorbing EGCG and distributing it to the brain and other tissues.

That's why researchers often use large dosages of concentrated EGCG in their studies instead of green tea.

But unfortunately, large dosages of concentrated EGCG have been shown to cause liver toxicity.

So you could supplement with large dosages of concentrated EGCG and see some benefits.

But you'd be damaging your liver at the same time.

Not good.

So what should you do? How do you absorb EGCG and get the amazing benefits of it without damaging your liver?

You take it with Vitamin C.

Research shows that you can enhance the absorption and availability of EGCG by taking it with Vitamin C (9).

That's why the Optimal Antiox supplement includes a small and safe amount of EGCG, plus 500 mg of Vitamin C.

This significantly enhances the absorption of EGCG, and ensures you get all the brain and mental health benefits of EGCG (without the harm).

 

24. Citicoline

Citicoline (also known as CDP-Choline) is one of the most bioavailable forms of choline, an essential B vitamin.

You need to get choline from food, but most people do not get enough because very few foods in the Western diet contain high levels of it.

That’s why supplementation is often necessary for optimal brain health.

Citicoline is a supplemental form of choline that has anti-inflammatory and neuroprotective effects.

Research shows that citicoline slows down the aging of mitochondria in the brain (125).

It also significantly enhances mitochondrial energy production and increases ATP levels in the frontal lobe of the brain (125).

Citicoline significantly improves my focus and mental energy.

You can also find some choline in foods such as beef liver and egg yolks, but the effects of Citicoline are much more noticeable and immediate because it quickly passes the blood-brain barrier and supports your brain.  

Make sure you read this article to learn more about the remarkable benefits of Citicoline.

 

25. Ginkgo Biloba

Ginkgo Biloba is a plant that has been used in China for thousands of years to treat a number of health problems.

It’s one of the top-selling natural supplements in the world, and it’s even a prescription herb in Germany.

Ginkgo Biloba is most commonly used to improve brain health because it increases brain blood flow and improves memory, mood, mental energy, and attention in both healthy and unhealthy individuals.

It even reduces the risk of dementia and Alzheimer’s disease!

Researchers have discovered that one of the ways it supports brain function is by improving mitochondrial function and increasing the production of ATP in brain cells (126-127).

It even restores ATP levels after mitochondrial damage (128).

Ginkgo Biloba is included in the Optimal Brain supplement.

29 Effective Ways to Increase Oxytocin Levels in the Brain

Man and woman kissing and increasing their oxytocin levels.

Oxytocin is a powerful hormone and neurotransmitter.

It’s often called the “love hormone" or “cuddle chemical” because it plays a key role in the emotional bond between a mother and her child.

It’s also released by both men and women when they are in love (116-118). 

But it isn’t just involved in loving relationships. 

It can also significantly affect the functioning of your brain and nervous system and impact your emotions day-to-day.

Low levels of oxytocin in the brain are associated with several mental health conditions, including depression, anxiety, social phobia, autism, schizophrenia, post-traumatic stress disorder, tinnitus, anorexia nervosa, and borderline personality disorder (120-135). 

And research suggests that if you increase oxytocin, it can lead to the following benefits:

Oxytocin clearly does a lot. 

Because of this, some doctors have started prescribing intranasal oxytocin spray to their patients to help them treat their symptoms (119). 

But you don’t necessarily need to run to your doctor and ask for a prescription. 

You can follow the 29 steps below and naturally increase your oxytocin levels yourself.

 

The Best Foods, Nutrients, Herbs and Supplements To Naturally Increase Oxytocin Levels in the Brain

1. Vitamin D

Vitamin D is a fat-soluble vitamin that your skin synthesizes when exposed to the sun. It can also be taken as a supplement.

Picture of the sun. The sun produces Vitamin D, which increases oxytocin levels in the brain.

Every tissue in your body has Vitamin D receptors, including the brain, so a deficiency can lead to costly physiological and psychological consequences.

Research shows that oxytocin is directly activated and controlled by Vitamin D (13-14).

Some researchers also believe that autistic children have low levels of oxytocin likely because they are deficient in Vitamin D (15-16). 

Ideally, you should get your Vitamin D naturally from the sun. 

It’s especially important to make sure you get some sunlight in the morning to set your circadian rhythm. 

But most people still don’t get enough Vitamin D from the sun, and that’s why I recommend taking a Vitamin D supplement or using a Vitamin D lamp.

Researchers estimate that 50 percent of the general population is at risk of Vitamin D deficiency (12). 

It's important to test and monitor your Vitamin D levels before and after supplementing with it.

Vitamin D also naturally increases dopamine levels in the brain, and being deficient in Vitamin D can make you more anxious and more depressed

 

2. Vitamin C

Vitamin C is another easy way to optimize and increase your levels of oxytocin. 

Researchers know that Vitamin C is a cofactor in the production of oxytocin, and the synthesis of oxytocin is dependent upon Vitamin C (17-18). 

One study found that Vitamin C stimulates the secretion of oxytocin (19). 

And another study found that supplementing with a high dose of Vitamin C increases the release of oxytocin, which then increases intercourse frequency, improves mood and decreases stress (20). 

As you probably know, Vitamin C is found in fruits and vegetables such as green peppers, citrus fruits, tomatoes, cauliflower, Brussels sprouts, broccoli, and cabbage.

In addition to getting Vitamin C from fruits and vegetables, I take a supplement with some Vitamin C.

I’ve taken up to 10 grams daily, and it definitely improves my mood and reduces stress and anxiety

Vitamin C is included in this supplement.

 

3. Magnesium

Magnesium is a vital mineral that participates in more than 300 biochemical reactions in your body. 

Unfortunately, lot of people are deficient in magnesium today (36-38).

A collection of magnesium-rich foods, including avocados, bananas, almonds, dark chocolate, spinach. Magnesium increases oxytocin levels in the brain.

This is a shame because magnesium is absolutely essential for the proper functioning of your nervous system and optimal neurotransmitter activity.

Researchers have found that the oxytocin receptor requires magnesium to function properly, and magnesium increases the action of oxytocin at the receptor (39-42).

There are a number of things you can do to make sure you’re getting enough magnesium.

First, make sure you’re eating magnesium-rich sources of food on a regular basis, including spinach, chard, pumpkin seeds, almonds, avocado, dark chocolate and bananas. These foods are included in my Free Grocery Shopping Guide for Optimal Mental Health.

Epsom salt baths are another great way to increase your body’s intake of magnesium

Magnesium supplements are also a good idea if you want to produce more oxytocin.

Magnesium is included in this supplement.

Besides supporting your oxytocin levels, magnesium can also naturally increase dopamine, reduce your anxiety, and help your overcome trauma, withdrawal and addiction

 

4. Taurine

Taurine is an organic compound found in food, particularly animal products. It has a wide variety of health benefits.

It can cross the blood-brain barrier, improve mood and produces anti-anxiety effects (1-10). 

Researchers believe that one of the ways it improves mood and reduces anxiety is by naturally increasing the release of oxytocin in the brain (11).

Taurine is included in the Optimal Calm supplement

5. Caffeine

Researchers have found that caffeine significantly increases the release of oxytocin (21-23). 

Perhaps this is one reason why people love getting together with friends for a coffee.

Coffee usually makes me sick because I’m extremely sensitive to mold and most coffee contains high amounts of mycotoxins (toxic metabolites produced by mold). 

But some coffee doesn’t. I usually drink one cup of high-quality coffee most mornings. I can also tolerate pure caffeine tablets.

Most people can tolerate regular coffee just fine. But if coffee makes you feel terrible and jittery, it might be the quality of the coffee. Consider trying higher-quality coffee, or simply take pure caffeine, and see how you feel. You’ll likely feel better than if you consumed low-quality coffee.

Coffee and caffeine can disrupt sleep though, so make sure you don’t drink it later in the day. I have my last cup sometime between 10 in the morning and noon. If I have it any later than that, it disrupts my sleep.

Lastly, it's also a good idea to try to consume the whole coffee fruit, instead of just the coffee bean or pure caffeine. 

Traditionally, the coffee bean is extracted from the coffee fruit for roasting. And the surrounding fruit is discarded. 

But that’s a huge problem.

Because the coffee fruit contains several healthy compounds not found in coffee beans themselves.

And after years of careful clinical research, scientists have discovered that ingesting whole coffee fruit concentrate significantly increases brain function

Coffee fruit concentrate is included in the Optimal Brain supplement

 

6. Estrogen

Estrogen is the primary female sex hormone and responsible for the development and regulation of the female reproductive system.

Estrogen has been found to increase the synthesis and secretion of oxytocin. It also increases the expression of oxytocin receptors in the brain (30). 

Other studies show that even just a single dose of estradiol can significantly increase circulating oxytocin levels and reduce anxiety (31-32).

I recommend both men and women get their hormone levels checked regularly, and then optimize them with hormone replacement therapy, especially if they want to produce more oxytocin and feel their best.

Not only can replacing estrogen increase your oxytocin levels, but it can also really improve your overall quality of life.

 

7. Lactobacillus Reuteri

Lactobacillus reuteri is a bacterium with anti-inflammatory effects that scientists first discovered in the 1980s. 

It’s one of the most promising psychobiotics for anxiety.

A woman holds her stomach and makes a heart shape around her belly button.

Research shows that Lactobacillus reuteri significantly increases oxytocin levels in the brain through the vagus nerve (26-29). 

Lactobacillus reuteri is usually found in the human gut. However, not all humans have it, and some people simply have very low levels of it.

Therefore, you may need to supplement with it to introduce and maintain high levels of it, especially if you want to produce more oxytocin.

One study found that the absence of lactobacillus reuteri causes social deficits in animals. By adding it back in to the guts of the animals, the researchers were able to reverse some of their behavioural deficits, which were similar to symptoms of social anxiety and autism in humans (24-25).

Lactobacillus reuteri is included in the Optimal Biotics supplement.

It's also found in breast milk, and some meat and dairy products.

 

8. Chamomile

You can also increase oxytocin with herbs, such as chamomile.

Chamomile is a medicinal herb that has been traditionally used for its calming and anti-inflammatory properties.

But it can also help you produce more oxytocin.

Animal studies show that chamomile contains substances that act on the same parts of the brain and nervous system as anti-anxiety drugs (47-48). 

Researchers also know that chamomile naturally increases oxytocin and lowers cortisol (49). 

 

9. Oleoylethanolamide (OEA)

Oleoylethanolamide (OEA) is a molecule produced in the body. It’s responsible for the feeling of being full after meals and may help with weight loss.

Multiple studies show that OEA naturally stimulates the secretion of oxytocin and increases levels of oxytocin in the brain (50-54). 

I haven’t tried it yet, but there are OEA supplements available online.

I’m going to try it and report back on how I feel. We’ll see if it helps me produce more oxytocin.  

 

10. Melatonin

Melatonin is a natural hormone released by your pineal gland, a small gland in your brain. It helps control your sleep and wake cycles (circadian rhythm), and adequate levels of melatonin are necessary to fall asleep quickly and sleep deeply throughout the night.

More than one study has shown that 500 mcg of melatonin significantly increases secretion of oxytocin (33-35). 

You can find supplements with 500 mcg of melatonin online.

A baby sleeping. Sleep increases oxytocin levels in the brain.

Or you can take this sleep supplement, which contains magnesium and a number of other natural compounds that I’ve used over the years to promote the production of melatonin.

Besides melatonin and sleep supplements, there are a number of other actions you can take to naturally produce more melatonin.

I work with my clients so that they can naturally produce more melatonin and maximize the quality of their sleep without so many supplements. We have free online workshop that talks about how you can work with us. You can register for the workshop here.

11. Fenugreek

Fenugreek is one of the most popular herbal supplements that has been traditionally used to enhance sex drive. 

It also demonstrates antidepressant and anti-anxiety effects in animals, and naturally produces more oxytocin in humans (55-57). 

I once experimented with a fenugreek supplement and I liked the effects. It felt like I produced more oxytocin when I was taking it, but I no longer take it regularly because all my other lifestyle habits are more than enough.

Fenugreek seeds are another option. They can be eaten whole, brewed into a tea, or even made into flour and baked into a gluten-free bread.

 

12. Jasmine Oil (Jasminum Officinale)

Jasmine Oil is a popular essential oil derived from the Jasminum Officinale flower. 

It’s been used for hundreds of years in Asia to improve mood, manage emotional stress and anxiety, and improve sex drive and sleep.

There is lots of research that suggests that it has positive affects on the nervous system (59-62). 

And a systematic study found that aromatherapy with Jasmine Oil can increase levels of oxytocin (58). 

After living in a moldy home, I researched and experimented with a number of essential oils. I found they supported my immune system and mood as I recovered. Here is the Jasmine Oil that I took.

It can either be inhaled through the nose or applied directly to the skin. You can also diffuse it in your home using a diffuser. 

 

13. Clary Sage Oil (Salvia sclarea)

Clary Sage Oil is a relaxing essential oil derived from the Salvia sclarea plant. 

Clary Sage essential oil increases oxytocin levels in the brain.

It’s been shown to naturally relieve anxiety and depression by reducing cortisol and improving thyroid hormone levels (63-66). 

And just last year, researchers found that inhaling Clary Sage Oil increases oxytocin in women during pregnancy (67-69). 

After living in a moldy home, I researched and experimented with a number of essential oils. I found they supported my immune system and mood as I recovered.

Just like Jasmine Oil, it can either be inhaled through the nose or applied directly to the skin. You can also diffuse it in your home using a diffuser.

 

14. Anise Seed (Pimpinella anisum)

Anise, also known as Pimpinella anisum, is a plant found in the same family as carrots, celery and parsley.

The plant produces a small white fruit called anise seed.

It’s rich in nutrients and can be used a natural remedy for a number of different health concerns.

Research shows that anise seed can increase oxytocin in pregnant women (183).

In one study, it was effective reducing symptoms of postpartum depression (184).

But it doesn’t just work in new mothers who have postpartum depression.

Another study showed that taking anise oil can decrease depressive symptoms in men and women with mild to moderate depression (185).

Anise seed can be taken by adding it to desserts and drinks.

Or you can use anise oil like they did in the depression study above.

 

The Best Lifestyle Habits, Therapies and Practices to Naturally Increase Oxytocin Levels in the Brain

15. Touch

Not surprisingly, there is a ton of research showing that interpersonal touch quickly increases oxytocin levels in the brain (107). 

This obviously includes kissing, cuddling, and sex. But non-sexual touch such as hugging and shaking hands increases oxytocin as well (105, 108-115).

A 10-second hug every day can help boost your immune system, fight infection, increase dopamine, reduce depression, and lessen fatigue (106). 

But Dr. Paul Zak, author of the Trust Factor, recommends much more than just one hug every day; he recommends eight hugs every day. 

So if you want to produce more oxytocin, get out there and start hugging people… just make sure it’s welcome by the other people. :)

 

16. Loving-Kindness Meditation

Loving-kindness meditation, or metta, is a meditation practice designed to enhance feelings of kindness and compassion for yourself and others.

While meditating, you repeat positive phrases to yourself, think positively of other people, and direct well-wishes and love towards them.

For example, you could close your eyes, simply think about a friend of family member, and repeat over and over that “they are wonderful”. Simply repeat this thought to yourself over and over, while pushing away any other negative thoughts that arise.

Researchers believe that you give yourself a boost in oxytocin when you do this and may even up-regulate oxytocin receptors (71). 

You can learn how to practice it here or through this video.

Loving-kindness meditation can also help you overcome trauma

17. Acupuncture

Acupuncture is an alternative treatment that has been shown to increase oxytocin levels (76). 

Research has shown that acupuncture can affect the synthesis, release and action of several neurotransmitters and neuropeptides, including oxytocin (72). 

Animal studies have also demonstrated that acupuncture elevates oxytocin concentration in certain brain regions (73-75). 

I’m a really big fan of auricular acupuncture for producing more oxytocin. Auricular acupuncture is when needles are inserted into ear. I’d recommend trying to find a health practitioner in your area who provides it, especially if you’re weening off psychiatric medication. It really helped me the first time I came off antidepressants. I was surprised.

In my experience, ear acupuncture is more effective than regular acupuncture. I’m not sure why. I’ve just personally noticed more benefits from ear acupuncture. 

I also use an acupuncture mat at home to relax before bed.

Acupuncture also naturally increases dopamine, stimulates the vagus nerve and increases blood flow to the brain.

 

18. Pets

A cute puppy lying on a couch. Pets increase oxytocin levels in our brains.

Animals have a way of calming us, and it’s because they increase our oxytocin levels. 

Research shows that just touching your pets lowers your blood pressure and increases your oxytocin levels.

One study found that oxytocin levels increased in both humans and dogs after just five minutes of petting. This may explain the emotional bonding between humans and dogs (77). 

Even just staring into your dog’s eyes can trigger the release of oxytocin in the brain and increase your levels (78). 

So if you’re trying to maximize your oxytocin levels, you should try to hang out with animals as much as possible, and consider getting a house pet if you don’t have one.

 

19. Massage

Research shows that massage can significantly increase oxytocin levels and reduce stress hormones (79, 83). 

This is why I personally get a massage from a registered massage therapist every couple of months. 

It’s important to note that one study found that a light massage is more effective at increasing oxytocin than a deep-tissue Swedish massage (80-82). 

So you may want to ask your massage therapist to take it easy and give you a gentle rubdown. 

 

20. Listen to Music and Sing

Music is actually healing and can have a calming effect on the brain by increasing oxytocin levels. 

A woman singing with a microphone. Singing increases oxytocin levels.

In one study, patients who underwent open-heart surgery listened to soothing music for 30 minutes one day after their surgery. And they had significantly higher levels of oxytocin compared to those who were simply told to rest in bed (86).

Slow-tempo music has also been shown to increase both oxytocin and heart-rate variability (88). 

What’s even better is singing along with the music. 

Researchers have found that singing for 30 minutes significantly increases oxytocin levels in both amateur and professional singers, regardless of whether they enjoyed singing the song (87, 91).

Perhaps this explains why mothers often sing lullabies to their newborn babies – it may encourage bonding by increasing the release of oxytocin. 

Lastly, making music together in a group leads to a significant release in oxytocin and reduction in stress (89-90).

So if you play an instrument, put together a band and start jamming. You’ll started producing more oxytocin together! :)

 

21. Yoga

Yoga is a popular “mind-body” relaxation technique that increases the activity of your parasympathetic “rest and digest” nervous system.

Researchers believe it works because it increases oxytocin levels in the brain by stimulating the vagus nerve (85). 

In one study, researchers found that yoga significantly increased oxytocin levels and improved socio-occupational functioning in patients with schizophrenia. The researchers concluded that yoga should be used to manage schizophrenia because of the improvement in oxytocin levels (84).

22. Socialize

I’ve already discussed how socializing can reduce cortisol and stimulate your vagus nerve

And now I’ve learned that positive social interactions can also increase oxytocin levels (93). 

Researchers have found that your brain releases more oxytocin during social contact and social bonding, and this can actually speed up healing from disease (92). 

So if you want to produce more oxytocin, my advice is to talk to people whenever you get the chance, and hang out with your friends and family as much as possible. I should probably be taking my own advice here because I’m an introvert and don’t socialize too much. 

But even just connecting through social media can increase oxytocin! It doesn’t necessarily need to be in person, although that’s definitely better.

 

23. Intermittent Drinking

You’ve probably heard of intermittent fasting. I’ve discussed it a lot in other articles. 

But you likely haven’t heard of intermittent drinking.

The typical mainstream advice is to drink eight glasses of water every day. 

A blond-haired woman drinking a glass of water. Intermittent drinking increases oxytocin levels in the brain.

I don’t follow that. I simply listen to my body and drink when I’m thirsty. 

And it appears that simply taking breaks from drinking water can increase oxytocin levels. 

Recent research shows that drought, and the “homeostatic disturbances” that lead to the “feeling of thirst”, activate specific oxytocin-producing parts of the brain (94-95). 

Researchers believe that “intermittent bulk drinking” could increase oxytocin signalling, recover human trust, and increase health by reducing stress and inflammation (94-95). 

If you think of it from an evolutionary perspective, this makes sense. Your ancestors likely consumed as much water as they could when they got the chance, but then went longer periods of time when they couldn’t and didn’t drink any water. 

Just like intermittent fasting, intermittent drinking doesn’t necessarily mean you drink less water throughout the day though.

You can simply drink a lot of water whenever you get thirsty. And then you stop drinking any water until you are thirsty again. 

That’s how all animals and human newborns behave. But we’ve been brainwashed to think we need to be sipping on water all the time. 

Start intermittent drinking, and your oxytocin receptors will thank you.

 

24. Warm and Cold Temperatures

Exposing yourself to both warm and cold temperatures can also increase oxytocin levels. 

Researchers have found that hot environments, warm temperatures and increased sweating activate specific oxytocin-producing parts of the brain (94-96). 

Giving birth in warm water has also been shown to reduce the need for doctors to give women synthetic oxytocin during labour. This suggests the warm water naturally increases oxytocin levels (186).

But it’s not just warm water and warm temperatures that increase oxytocin.

Recent research also suggests that cold exposure significantly upregulates oxytocin levels in the brain (97-100). 

So if you want to optimize your oxytocin levels, try pushing yourself outside your comfort zone and expose your body to the acute stress of extreme temperatures.

What I like to do is take a warm shower, but then finish it off with 1-2 minutes of cold. 

Cold showers also stimulate the vagus nerve

 

25. Eat (Healthy) Food

Eating food also increases oxytocin, and it’s easily accessible by anyone. 

Food activates touch receptors in your mouth, which then stimulates the release of oxytocin (102). 

And then when food reaches your gut, a hormone is released from the intestines that activates the vagus nerve, which then stimulates the release of more oxytocin in the brain (102-104). 

This is why eating makes people feel calm and satisfied, and often opens them up for social interaction, bonding and attachment.

The obvious downside to all of this is that you may be tempted to overeat unhealthy foods to stimulate the release of oxytocin, so that you feel better and less stressed. And oxytocin is one reason why you may have a hard time breaking bad eating habits. 

But don’t worry; just stick to the healthy foods included in my free grocery shopping guide and you won’t have a problem

 

26. Watch a Movie

Everyone loves a good movie.

And it’s probably because it increases oxytocin.

Research shows that compelling narratives cause the synthesis and release of oxytocin (101). 

And this has the power to affect our attitudes, beliefs, and behaviours (101). 

 

27. Give Someone A Gift

Everyone loves receiving a gift.

But it turns out that giving someone a gift benefits you, the gift-giver, as well.

Studies show that receiving and giving gifts increasing oxytocin levels in the brain.

 

28. Hypnosis

Hypnosis - also known as hypnotherapy or hypnotic suggestion - is a trance-like state.

When you’re in this state, you have heightened focus and concentration, and reduced peripheral awareness.

You’ll also have an enhanced capacity to respond to suggestion.

Hypnosis is usually done with the help of a therapist using verbal repetition and mental images.

Researchers believe that the benefits of hypnosis may be due to its oxytocin-increasing effects (182).

 

29. Volunteer

Volunteering is another excellent way to boost your own oxytocin.

A study published in the journal Hormones and Behavior found that charitable behaviour reduces stress and improves health by increasing oxytocin levels (187).

So get out there and volunteer at your local food bank already!

The 32 Best Ways to Increase GDNF

Glial cell line-derived neurotrophic factor (GDNF) is a protein that’s critical for optimal brain function and mental health. 

It plays an important role in the survival and growth of certain types of neurons in the brain and nervous system. 

For example, it supports the growth and survival of dopamine neurons, which are critical for movement and cognitive function.

As a result, low levels of GDNF have been associated with several neurological disorders, including Parkinson's disease and depression.

But luckily, there are numerous ways for you to increase your GDNF levels. 

This article shares the 32 best ways to increase GDNF. 

The article includes five main sections: 

  • The benefits of increasing GDNF and how it affects your brain

  • The medical conditions and symptoms associated with low GDNF levels 

  • The best lifestyle habits, therapies and practices to increase GDNF levels in the brain

  • The best foods and nutrients you should eat to raise GDNF

  • And the best herbs and natural supplements for boosting GDNF 

Continue reading to learn more and discover how you can naturally improve your GDNF levels

The Benefits of Increasing GDNF and How It Affects Your Brain

GDNF (glial cell line-derived neurotrophic factor) is a protein that plays an essential role in the development and survival of dopaminergic neurons in the central and peripheral nervous systems. 

It acts by binding to specific receptors on the surface of cells, including neurons, and activating intracellular signaling pathways that promote cell survival, differentiation, and growth.

In the brain, GDNF is primarily found in the striatum, substantia nigra, and the cortex, which are regions of the brain associated with motor control, reward, and cognition. 

Studies suggest that GDNF can modulate synaptic plasticity, which is the ability of brain cells to change the strength and structure of their connections in response to new experiences (98-101).

Overall, the exact mechanisms by which GDNF affects the brain are still being investigated, but it is very clear that this protein plays a critical role in neuronal survival, function, and plasticity.

As a result, increasing levels of GDNF can have several potential benefits for brain function and mental health, including:

Neuroprotection: GDNF has been shown to protect neurons against damage, degeneration and death. Increasing GDNF could have potential therapeutic implications, and possibly slow down or prevent the progression of neurodegenerative disorders like Parkinson's disease, Alzheimer's disease, and amyotrophic lateral sclerosis (102-106).

Improved motor function: GDNF has been linked to improved motor function in animal studies, suggesting that it could be used to treat motor disorders and improve motor function in individuals with Parkinson's disease and Huntington's disease (107-111).

Pain relief: Studies have suggested that GDNF could have analgesic (pain-relieving) effects, potentially providing pain relief for chronic pain conditions. (112-116).

Improved cognition: Animal studies have shown that GDNF can enhance cognitive function, suggesting it could improve learning, memory, and cognitive function in humans as well. As a result, increasing GDNF levels may help to support cognitive performance and prevent cognitive decline, and even be a therapeutic target for cognitive impairments like Alzheimer's disease (117-119).

Enhanced neuronal growth and development: GDNF has been shown to promote the growth and differentiation of new neurons in the brain, suggesting it could have potential benefits for neurological disorders that involve impaired neuronal development, like autism spectrum disorder (120-122).

Neuronal repair: Increasing GDNF levels could also potentially enhance the brain's ability to repair itself following injury or damage. GDNF has been shown to promote the growth and repair of neurons, helping to replace damaged or lost neurons. This could potentially be beneficial in conditions where neurons are lost or damaged, such as in stroke or traumatic brain injury (123-125).

Anti-inflammatory effects: GDNF has been shown to have anti-inflammatory effects in the brain (126-128).

Protection against ischemia: GDNF has been shown to protect against ischemia, which is a lack of blood flow to tissues or organs, including the brain. This could have therapeutic implications for conditions like stroke (129-131).

Protection against oxidative stress: GDNF has been shown to protect against oxidative stress, which is a key factor in the development of several diseases, including Alzheimer's disease and Parkinson's disease. (132-134).

Reduced anxiety and depression: GDNF has been found to have anxiolytic and antidepressant effects in preclinical studies, indicating its potential as a treatment for mood disorders. (135-136).

 

Conditions and Symptoms Associated with Low GDNF Levels

Research shows that low levels of GDNF have been associated withseveral brain and mental health conditions and symptoms, including:

Parkinson's disease: Parkinson's disease is a progressive neurodegenerative disorder that affects movement. Low levels of GDNF have been found in the brains of individuals with Parkinson's disease, and research has suggested that increasing GDNF levels may have therapeutic potential for the treatment of the disease (5-6).

Alzheimer's disease: Alzheimer's disease is a progressive neurodegenerative disorder that affects memory and cognitive function. Low levels of GDNF have been found in the brains of individuals with Alzheimer's disease, and some studies have suggested that GDNF may have neuroprotective effects that could potentially slow the progression of the disease (7). 

Depression: Low levels of GDNF have been found in individuals with depression, and some studies have suggested that GDNF may have antidepressant effects (8-11).

Chronic Pain and Fibromyalgia: Chronic pain is a persistent pain that lasts for weeks, months, or even years. Fibromyalgia is a chronic pain disorder that affects the muscles and soft tissues. Low levels of GDNF have been found in individuals with chronic pain and fibromyalgia, and some studies have suggested that GDNF may have analgesic (pain-relieving) effects (81-82). 

Eating disorders: Eating disorders are a group of mental health conditions that are characterized by abnormal eating habits and behaviors. Low levels of GDNF have been found in individuals with eating disorders, and some studies have suggested that GDNF may be involved in the regulation of food intake and body weight (83-84). 

Amyotrophic Lateral Sclerosis (ALS): ALS is a progressive neurodegenerative disease that affects the nerve cells responsible for controlling voluntary muscle movement. Low levels of GDNF have been found in individuals with ALS, and some studies have suggested that GDNF may have therapeutic potential for the treatment of the disease (85). 

Multiple Sclerosis (MS): MS is a chronic autoimmune disease that affects the central nervous system. Low levels of GDNF have been found in individuals with MS, and some studies have suggested that GDNF may have neuroprotective effects that could potentially slow the progression of the disease (86-87). 

Schizophrenia: Schizophrenia is a severe mental disorder that affects how a person thinks, feels, and behaves. Low levels of GDNF have been found in individuals with schizophrenia, and some studies have suggested that GDNF may be involved in the regulation of dopamine, a neurotransmitter that is implicated in the development of the disorder (88-89). 

Huntington's disease: Huntington's disease is a genetic disorder that causes progressive brain damage, leading to motor, cognitive, and psychiatric symptoms. Low levels of GDNF have been found in individuals with Huntington's disease, and some studies have suggested that GDNF may have therapeutic potential for the treatment of the disease (90-91). 

Addiction: Low levels of GDNF have been found in individuals with drug and alcohol addiction, and some studies have suggested that GDNF may be involved in the regulation of reward pathways in the brain, which could potentially contribute to the development of addiction (92). 

Tinnitus: Tinnitus is a condition that causes ringing or other sounds in the ears, often associated with hearing loss. Low levels of GDNF have been found in individuals with tinnitus, and some studies have suggested that GDNF may have therapeutic potential for the treatment of the condition (93-94). 

Epilepsy: Epilepsy is a neurological disorder that causes seizures. Low levels of GDNF have been found in individuals with epilepsy, and some studies have suggested that GDNF may have anticonvulsant effects that could potentially reduce the frequency and severity of seizures (95-97). 

Perhaps you struggle with one of these conditions or symptoms. 

The good news is that you’re not powerless.

You can do something about it. 

You have the power to increase your GDNF levels and improve your brain function and mental health. 

All you need to do is implement some of the strategies below. 

Many of these methods have been helpful to me over the years.

And they can help you too. 

Let’s jump into them.

 

The Best Lifestyle Habits, Therapies and Practices to Increase GDNF Levels in the Brain

1. Exercise

Regular exercise has been found to increase GDNF levels in the brain.

In a study published in the Journal of Neuroscience, researchers found that voluntary wheel running increased GDNF levels in the hippocampus, a region of the brain important for learning and memory (1). 

Another study found that treadmill running increased GDNF levels in the substantia nigra, a region of the brain affected in Parkinson's disease (2). 

And in a study published in the journal Neurobiology of Learning and Memory, researchers found that voluntary running on a wheel increased GDNF levels in the hippocampus and cortex of rats and that this increase was associated with improved cognitive function (4). 

Both aerobic and resistance exercise are effective at increasing GDNF in the brain and spinal cord, but research has shown that high-intensity aerobic exercise is most effective at stimulating the production of GDNF (3).

Exercise has also been shown to protect against cognitive decline and dementia, promote neurogenesis, help reverse brain damage, and promote the regeneration of myelin.

So not surprisingly, exercise is recommended by many experts and it’s often their number one piece of advice for optimal brain health.

My usual advice is to find a sport or exercise routine that you enjoy so that you’ll stick with it consistently.

 

2. Intermittent Fasting

Intermittent fasting, which involves alternating between periods of fasting and eating, may be an effective way to increase GDNF levels.

Fasting allows your digestive system to take a break and triggers the release of hormones and neurotransmitters, including GDNF.

Studies have shown that intermittent fasting can increase GDNF levels in the brain.

A study published in the journal Experimental Gerontology found that alternate-day fasting increased GDNF levels in the hippocampus (12). 

Other studies have shown that intermittent fasting increases GDNF levels in the striatum, hippocampus and cortex (13). 

And then a study published in the journal Brain Research found that intermittent fasting increased GDNF levels in the hippocampus and that this increase was associated with improved cognitive function (14). 

I often eat all my food for the day within an 8-hour window, and then fast for the rest of the day. 

The best way to start fasting is by eating dinner around 6, not eating anything after that before bed, and then eating a regular breakfast the next day. That should give you about 12-14 hours of fasting time.

 

3. Heat Shock Proteins

Heat shock proteins (HSPs) are a group of proteins that are produced in response to stress, such as heat stress (sauna) or exercise.

HSPs have been found to increase GDNF levels in the brain.

In one study, researchers found that treatment with HSP70 increased GDNF expression (29). 

Another study showed that treatment with HSP90 increased GDNF expression in neurons (30). 

And then further research found that treatment with HSP70 increased GDNF levels in the hippocampus (31).

Using a sauna regularly is one way to increase your body’s production of heat shock proteins.

Once you start using a sauna, you should listen to your body to determine how much time you should spend in it. Start out slowly and increase the length of your sessions over time.  

Also, make sure to drink lots of water before and after each session, and never consume alcohol in combination.  

Check out this post to learn more about saunas and the 13 ways they can improve your brain function and mental health.

 

4. Acupuncture

Acupuncture is a traditional Chinese medicine technique that involves inserting thin needles into specific points on the body to stimulate various physiological processes. 

There is some research suggesting that acupuncture increases GDNF levels.

One study published found that electro-acupuncture treatment increases GDNF levels in the spinal cord of rats with sciatic nerve injury (32). 

Another study published in the journal Acupuncture in Medicine found that acupuncture treatment increased GDNF levels in the brain and spinal cord of rats with Parkinson's disease (33). 

Researchers have also found that acupuncture treatment increases GDNF levels in the striatum and substantia nigra of rats with Parkinson's disease (34). 

I’m personally a really big fan of auricular acupuncture. Auricular acupuncture is when needles are inserted into the ear. I’d recommend trying to find a health practitioner in your area who provides it, especially if you’re weaning off psychiatric medication. It really helped me the first time I came off antidepressants. I was surprised.  

At the end of each appointment, my practitioner would secure small black seeds on my ear.  

In my experience, ear acupuncture is more effective than regular acupuncture.  

I also sometimes lay on an acupuncture mat at home to relax before bed.

5. Caloric Restriction

Caloric restriction has been shown to increase GDNF levels in various studies.

A study published in the journal Brain Research Bulletin found that caloric restriction increased GDNF levels in the striatum of mice (35). 

Researchers have also found that caloric restriction increases GDNF levels in the hippocampus, striatum and cortex of rats (36-37). 

I typically don’t recommend restricting calories too much because it can add too much stress on the body, which can ultimately end up making chronic illness worse in the long run. Intermittent fasting is preferably over restricting calories.

 

6. Low-level Laser Therapy (LLLT)

Low-level laser therapy (LLLT), or photobiomodulation, is a treatment that uses low-level (low-power) lasers or light-emitting diodes (LEDs) to stimulate brain cells, helping them function better.  

Dr. Norman Doidge, a psychiatrist and researcher who teaches at the University of Toronto, discusses the amazing effects of LLLT in his book The Brain’s Way of Healing.

Researchers have investigated the effects of low-level laser therapy (LLLT) on GDNF levels in a rat model of Parkinson's disease. 

The researchers found that treatment with LLLT increased GDNF levels in the striatum, a brain region involved in motor function, and improved motor function in these rats. The researchers suggested that the neuroprotective effects of LLLT may be mediated, at least in part, by the upregulation of GDNF (55). 

In another study, researchers looked at the effects of LLLT on GDNF levels in the hippocampus, a brain region involved in learning and memory, in a rat model of Alzheimer's disease. The researchers found that treatment with LLLT increased GDNF levels in the hippocampus and improved cognitive function in these rats. The researchers suggested that the neuroprotective effects of LLLT may be mediated, at least in part, by the upregulation of GDNF (56). 

I previously wrote about my experience with low-level laser therapy here.  

I use this device and shine the red and infrared light on my forehead for 5 minutes every day. I also shine it on other parts of my head and on my entire body, including on my thyroid, thymus gland and gut. I have experienced incredible benefits from doing this. 

You can also use this smaller and more convenient device and shine it on your forehead. 

You can also use the Vielight Neuro Duo, which is a transcranial-intranasal headset with 810 nm of near infrared light. It penetrates deeper into brain tissue and is absorbed better by the central nervous system. If you decide to try a Vielight device, you can use the coupon code JORDANFALLIS for a 10% discount

Before trying LLLT, I highly recommend reading my full article about it first.

 

7. Meditation

Meditation is a practice that involves training the mind to focus and achieve a state of relaxation and heightened awareness. 

It has been shown to have a variety of benefits for physical and mental health, including reducing stress, anxiety, and depression, improving focus and concentration, and increasing feelings of well-being.

Some studies suggest that regular meditation practice is associated with higher GDNF levels in the brain (58). 

Researchers found that a six-week meditation program was associated with increased GDNF levels in the blood of participants with chronic pain (57). 

Meditation is one of my favourite daily activities and treatments to maintain optimal brain function and mental health.

I recommend the Muse headband to meditate. It gives you real-time feedback while you meditate. It makes meditation a lot more fun and tolerable.

I previously wrote about it here, and you can get it through the Muse website.

 

8. Yoga

Yoga is a mind-body practice that involves physical postures, breathing exercises, and meditation. Yoga can help reduce stress and promote neuroplasticity.

Some studies have shown that yoga can increase GDNF levels in human subjects. 

In one study, researchers found that practicing yoga was associated with increased GDNF levels in healthy individuals. 

The study involved 24 healthy adults who practiced yoga for one hour per day, five days per week, for six weeks. Blood samples were collected before and after the intervention, and GDNF levels were measured.

The study found that practicing yoga was associated with a significant increase in GDNF levels compared to baseline. The authors of the study suggest that the increase in GDNF levels may be related to the physical and mental benefits of yoga, such as increased physical activity, reduced stress, and improved mood (59). 

Despite all the great research, I’m personally not a big fan of yoga. A lot of people swear by it but it’s just not for me. I prefer meditation and tai chi.

 

9. Transcranial Magnetic Stimulation

Transcranial magnetic stimulation (TMS) is a non-invasive brain stimulation technique that uses a magnetic field to stimulate nerve cells in the brain. 

Some studies suggest that TMS increases GDNF levels in the brain.

In one study, researchers found that TMS was associated with increased GDNF levels in the brains of rats. The study involved exposing rats to TMS for 10 minutes per day, five days per week, for four weeks. The researchers found that TMS was associated with a significant increase in GDNF levels in the rats' brains compared to a control group (60). 

Another study found that TMS was associated with increased GDNF levels in the brains of mice. The study involved exposing mice to TMS for 20 minutes per day, five days per week, for three weeks. The researchers found that TMS was associated with a significant increase in GDNF levels in the mice's brains compared to a control group (61). 

I don’t have any personal experience with TMS. I investigated it but never ended up doing it myself and never ended up needing it. It can sometimes help people who have treatment resistant depression. But I think it should be a last resort and other alternatives should be explored first.

 

10. Massage

Massage therapy is a manual therapy that involves the manipulation of soft tissues. 

Some studies have shown that massage therapy can increase GDNF levels in human subjects.

For example, a study found that massage therapy increased GDNF levels in the saliva of healthy adults. The study involved administering a 15-minute massage to the participants and collecting saliva samples before and after the massage. The researchers found that GDNF levels in the saliva were significantly higher after the massage compared to before the massage (66). 

Another study published in the journal Brain Research Bulletin found that massage therapy increased GDNF levels in the blood of rats. The study involved administering a 10-minute massage to the rats and measuring GDNF levels in the rats' blood. The researchers found that massage therapy was associated with a significant increase in GDNF levels in the rats' blood compared to a control group (67). 

This is one reason why I regularly get a massage from a registered massage therapist. 

Massage also reduces cortisol, increases dopamine and oxytocin, and stimulates the vagus nerve.

11. Deep Sleep

Deep sleep can help promote neuroplasticity and supports the growth and survival of neurons. 

Getting adequate sleep has also been shown to increase GDNF levels in animal models and some human studies. 

For example, a study published in the Journal of Sleep Research found that sleep deprivation was associated with lower levels of GDNF in the blood of healthy adults. 

The study involved measuring GDNF levels in the blood of participants after they had either a full night's sleep or a night of total sleep deprivation. The researchers found that GDNF levels were significantly lower after the night of sleep deprivation compared to the full night's sleep (70). 

Another study published in the journal Neurology found that poor sleep quality was associated with lower levels of GDNF in the cerebrospinal fluid of older adults. 

The study involved measuring GDNF levels in the cerebrospinal fluid of older adults who reported poor sleep quality or good sleep quality. The researchers found that GDNF levels were significantly lower in the cerebrospinal fluid of older adults who reported poor sleep quality compared to those who reported good sleep quality (71). 

I used to have very poor sleep and it was one of the main factors that contributed to my poor cognitive function. 

If you’re having trouble with sleep, try this sleep supplement. It contains magnesium and other natural compounds that I’ve used over the years to promote deeper and more restful sleep. 

I also work with my clients so that they can naturally produce more melatonin and maximize the quality of their sleep without so many supplements. We have a free online workshop that talks about how you can work with us. You can register for the workshop here.

 

12. Music Therapy

Music therapy is a technique that involves the use of music to improve physical and emotional health. 

Some studies have shown that music therapy can increase GDNF levels in humans.

For example, a study published in the journal Brain Sciences found that listening to music for 30 minutes was associated with a significant increase in GDNF levels in the blood of healthy adults. 

The study involved measuring GDNF levels in the blood of participants before and after they listened to music for 30 minutes. The researchers found that GDNF levels were significantly higher after listening to music compared to before (72). 

Another study found that a music therapy intervention was associated with higher GDNF levels in the saliva of patients with Parkinson's disease. 

The study involved a 10-week music therapy intervention in which patients listened to music and engaged in other musical activities. The researchers found that GDNF levels in the saliva of patients were significantly higher after the intervention compared to before (73). 

It’s even more effective when you’re learning or listening to music that you really enjoy.

I previously wrote about how music can also naturally reduce cortisol, increase dopamine and oxytocin, and help treat OCD

 

13. Cognitive Behavioral Therapy

Cognitive behavioral therapy (CBT) involves challenging and changing unhelpful cognitive distortions and behaviors, improving emotional regulation, and developing personal coping strategies.

Studies suggest that CBT can have a positive impact on GDNF levels.

For example, a study published in the Journal of Clinical Psychology found that CBT was associated with an increase in GDNF levels in patients with major depressive disorder.

The study involved measuring GDNF levels in the blood of patients before and after they received 16 weeks of CBT. The researchers found that GDNF levels were significantly higher after CBT compared to before (74). 

Another study published in the journal Psychiatry Research found that CBT was associated with higher GDNF levels in patients with social anxiety.

The study involved measuring GDNF levels in the blood of patients before and after they received 12 weeks of CBT. The researchers found that GDNF levels were significantly higher after CBT compared to before (75). 

I personally never found CBT helpful for my mental health issues but other people do. 

 

14. Cold Exposure

Cold exposure, such as cold showers or immersion in cold water, has been shown to increase GDNF levels in animal models and some human studies. 

For example, researchers found that cold water immersion was associated with an increase in GDNF levels in healthy volunteers. 

The study involved immersing the participants in cold water for 20 seconds, followed by a 10-second break, for a total of 10 cycles. The researchers found that GDNF levels were significantly higher after cold water immersion compared to before (76). 

Another study found that repeated cold exposure was associated with higher GDNF levels in the brains of rats. 

The study involved exposing the rats to cold temperatures for 1 hour per day for 5 days. The researchers found that GDNF levels were significantly higher in the brains of the rats that were exposed to cold temperatures compared to the control group (77). 

Cold exposure can help reduce inflammation and promote blood flow, which may indirectly increase GDNF levels as well. 

I personally take a cold shower every day.

During the winter, I’ll also go outside for short periods of time with hardly any clothes. It boosts my dopamine and increases my motivation. 

You don’t have to be that extreme though.

You can start by finishing your next shower with one minute of cold water.

See how it feels, and then over time, increase the amount of time you turn off the hot. 

It can be a bit painful. 

But the beneficial effects end up being worth it. 

Another way is to stick your face, hand or foot in ice cold water.

Or you can try cold plunges, cold baths and even cryotherapy if you want.

Find what works best for you and do it regularly.

 

15. Neurofeedback

Neurofeedback is a technique that involves the use of electronic sensors to monitor brain activity and provide feedback to the individual. 

Some studies have shown that neurofeedback can increase GDNF levels in humans. 

For example, researchers found that neurofeedback training was associated with an increase in GDNF levels in healthy participants. The study involved training the participants using a specific neurofeedback protocol designed to increase alpha activity in the brain. The researchers found that GDNF levels were significantly higher in the participants who received neurofeedback training compared to a control group (78). 

Personally, neurofeedback was one of the most impactful actions I took to overcome severe anxiety

It works at a deep subconscious level, breaking the cycle of chronic anxiety.  

It shifts you into a natural, healthier state of mind.  

If you want to try neurofeedback, it’s best to work with a qualified neurofeedback practitioner.  

If you’re interested in neurofeedback, I recommend becoming a client and working with us to determine the best type of neurofeedback for you and your condition. I have found that some types of neurofeedback are completely ineffective and may even be harmful. So it’s very important to do the right type of neurofeedback that actually works. It’s also critical to work with a qualified neurofeedback practitioner who knows what they are doing. Otherwise, you can get worse. We help our clients find a qualified practitioner in their area.

I also sometimes recommend the Muse headband. It’s a decent substitute to real neurofeedback and gives you real-time feedback on your brain waves while you meditate. 

I previously wrote about the Muse headband here, and you can get it through the Muse website. But keep in mind that it’s definitely not as good as clinical neurofeedback.

 

16. Hyperbaric Oxygen Therapy

Hyperbaric oxygen therapy (HBOT) is a medical treatment that involves breathing pure oxygen in a pressurized environment. 

It can enhance healing and recovery after injury to the central nervous system.

Usually, oxygen is transported throughout the body only by red blood cells. But with HBOT, oxygen is dissolved into all body fluids, including the fluids of the central nervous system.

This leads to oxygen being carried to areas of the body where circulation is diminished or blocked. As a result, extra oxygen can reach all damaged tissues, including areas that need to heal.

Researchers have investigated the effects of HBOT on GDNF levels in patients with acute ischemic stroke. The study found that HBOT led to a significant increase in GDNF levels in the patients' blood serum, suggesting that HBOT may have neuroprotective effects in stroke patients by increasing GDNF levels (80). 

Another study looked at the effects of HBOT on GDNF levels in rats with traumatic brain injury. The study found that HBOT significantly increased GDNF levels in the rats' brains, suggesting that HBOT may have neuroprotective effects by increasing GDNF levels (79). 

You’ll need to find a qualified practitioner or clinic in your area that provides this treatment.

The Best Foods and Nutrients to Increase GDNF Levels in the Brain

17. Omega-3 Fatty Acids

Omega-3s fatty acids are the highest quality fats for the brain.

They are essential, meaning your body cannot create them and you have to get them from food or supplements.

Omega-3s fatty acids are found in fish oil, and making sure you get more omega-3s is one of the most important actions you can take to support your brain and nervous system. 

Many studies show that they significantly reduce brain inflammation; improve memory, mood and cognition; and protect against mild cognitive impairment, dementia and Alzheimer's disease.

Research also shows that they increase GDNF levels in the brain, which may contribute to their neuroprotective effects.

A study published in the journal Neuroscience Letters found that treatment with omega-3 fatty acids increased GDNF levels in the hippocampus and striatum (15). 

Another study published in the journal Neuroscience Letters found that treatment with omega-3 fatty acids increased GDNF levels in the hippocampus and cortex, and that this increase was associated with improved cognitive function (16). 

And then a study published in the journal PLoS One found that treatment with omega-3 fatty acids increased GDNF levels in the hippocampus and improved cognitive function (17). 

Omega-3 fatty acids are found in cold water fish such as salmon, black cod, sablefish, sardines and herring. 

Unfortunately, most people don't consume enough of these foods.

So supplementing with krill oil should be considered. 

Krill oil is a special kind of fish oil that readily crosses the blood-brain barrier. I’ve tried tons of fish oil supplements, and I recommend krill oil over all the others.

 

18. Lithium

Lithium is predominantly known as a medication given to bipolar patients to manage their symptoms. 

However, it’s also an essential mineral.

Bipolar patients are often given high doses of lithium carbonate.

But low doses of lithium orotate can be safely supplemented to improve your brain health and increase GDNF levels in the brain. 

In fact, it is believed that the neuroprotective effects of lithium in certain neurodegenerative diseases such as Parkinson's and Alzheimer's may be due in part to its ability to increase GDNF levels.

One study found that treatment with lithium increased GDNF levels in the hippocampus of rats (24). 

Another study found that chronic treatment with lithium increased GDNF levels in the prefrontal cortex and hippocampus (25). 

I used to take lithium orotate. I don’t take it anymore because I don’t need it, but I remember it making me feel calm and stable. 

 

19. Blueberries

If you want to improve your cognitive performance, eating lots of fruits and vegetables is definitely something you’ll want to do regularly.  

Blueberries are particularly potent because they are so rich in anthocyanins.

Anthocyanins have been found to increase GDNF levels in the brain and improve cognitive function.

One study found that anthocyanin-rich extracts from blueberries, blackberries, and raspberries increased GDNF levels in astrocytes and in the hippocampus (28). 

Researchers have also found that supplementation with blueberry extract improves spatial memory and increased the expression of genes related to neuroplasticity, including GDNF (26). 

Another study showed that supplementation with blueberry powder improved cognitive function in older adults and increased the activation of brain regions involved in cognitive processing, including the prefrontal cortex, which has been shown to be affected by GDNF (27). 

If you eat blueberries, make sure they are wild because they are richer in polyphenols.  

I buy wild blueberries every time I go grocery shopping. 

They are included in my Free Grocery Shopping Guide for Optimal Brain Health.  

I try to eat one cup of them every day to support my brain health.  

Alternatively, you can take a blueberry extract.

In fact, most researchers use a concentrated blueberry extract instead of actual blueberries when they study the beneficial health effects of blueberries. 

It’s actually less expensive in the long run to take an extract than eat blueberries every day, but I just prefer to eat actual blueberries. It’s more enjoyable.  

You can also drink blueberry juice if you want. There is research showing that blueberry juice improves cognitive function in the elderly. 

Besides increasing GDNF, wild blueberries also improve brain health by increasing acetylcholine, increasing BDNF, and improving brain blood flow.

 

20. Green Tea (EGCG)

There have been several studies investigating the potential neuroprotective effects of green tea and its active polyphenols, including epigallocatechin gallate (EGCG), on the brain. 

It has been suggested that green tea consumption increases GDNF levels.

One study published in the journal Nutrients found that treatment with epigallocatechin gallate (EGCG) increased GDNF levels in the hippocampus of rats with traumatic brain injury (38). 

Another study published in the journal Brain Research found that treatment with green tea extract increased GDNF levels in the hippocampus of rats with chronic cerebral hypoperfusion (39).

Researchers have also found that treatment with EGCG increases the levels of GDNF in neurons, suggesting that green tea consumption may have neuroprotective effects by promoting the production of GDNF (40). 

Lastly, a study published in the Journal of Nutritional Biochemistry in 2013 investigated the effects of green tea extract on GDNF levels in the brains of mice with Parkinson's disease. The researchers found that treatment with green tea extract increased GDNF levels in the brains of these mice. It also improved their motor function and reduced oxidative stress (41). 

It's worth noting that these studies used either green tea extract or EGCG rather than regular green tea, and the effects on GDNF levels may differ depending on the specific dose and form of green tea consumed.

It’s also important to keep in mind that the body isn't very good at absorbing EGCG from green tea and distributing it to the brain and other tissues.  

That's why researchers often use large dosages of concentrated EGCG in their studies instead of green tea.  

But unfortunately, large doses of concentrated EGCG have been shown to cause liver toxicity.  

So you could supplement with large dosages of concentrated EGCG and see some benefits.  

But you'd be damaging your liver at the same time.  

Not good.  

So what should you do? How do you absorb EGCG and get the amazing benefits of it without damaging your liver?  

You take it with Vitamin C.  

Research shows that you can enhance the absorption and availability of EGCG by taking it with Vitamin C

That's why the Optimal Antiox supplement includes a small and safe amount of EGCG, plus 500 mg of Vitamin C.  

This significantly enhances the absorption of EGCG, and ensures you get all the brain and mental health benefits of EGCG (without the harm).  

 

21. Zinc

Zinc is an essential mineral that is involved in many physiological processes in the body, including brain function. 

There is some research suggesting that zinc may play a role in regulating the levels of GDNF in the brain.

Researchers have investigated the effects of zinc deficiency on GDNF levels in the brains of rats. The researchers found that zinc deficiency led to a decrease in GDNF levels in the striatum, a brain region involved in motor function, and that this decrease was associated with impaired motor coordination (42). 

Another study looked at the effects of zinc supplementation on GDNF levels in the brains of rats with spinal cord injury. The researchers found that zinc supplementation increased the levels of GDNF in the spinal cord and improved motor function in these rats (43). 

I created the Optimal Zinc supplement so that my readers and followers make sure their zinc levels are optimal. I created it because I want to give my readers and followers the very best zinc supplement so that they can experience superior results. I have found that many zinc supplements on the market fall short. Optimal Zinc includes several other nutrients  and co-factors that increase the absorption of zinc.  

Besides supplementing with zinc, you should also eat plenty of healthy, whole foods that contain zinc.

Some of the best foods to optimize your zinc levels include:

  • Oysters

  • Grass-fed beef

  • Pumpkin seeds

  • Cashews

  • Mushrooms

  • Spinach

These foods are included in my Free Grocery Shopping Guide for Optimal Brain Health.

 

22. Vitamin D

Vitamin D is a fat-soluble vitamin that your skin synthesizes when exposed to the sun.

But most people still don’t get enough Vitamin D from the sun. 

Researchers believe that 50% of people are at risk of Vitamin D deficiency.

And low vitamin D levels have been associated with lower GDNF levels. 

But there is some research suggesting that vitamin D supplementation may be able to increase the levels of GDNF in the brain.

A study published in the Journal of Clinical Neuroscience in 2012 investigated the relationship between vitamin D levels and GDNF levels in the blood of patients with Parkinson's disease. 

The researchers found that patients with higher vitamin D levels had higher GDNF levels in their blood, suggesting a positive correlation between vitamin D and GDNF (48). 

Researchers also investigated the effects of vitamin D supplementation on GDNF levels in the brains of rats with Parkinson's disease. 

The researchers found that treatment with vitamin D increased the levels of GDNF in the substantia nigra, a brain region involved in motor function, and that this increase was associated with improved motor function in these rats (46). 

Another study looked at the effects of vitamin D supplementation on GDNF levels in the brains of rats with cerebral ischemia-reperfusion injury. 

The researchers found that treatment with vitamin D increased the levels of GDNF in the brain and improved neurological function in these rats (47). 

Sun exposure, foods, and supplements can help you maintain healthy vitamin D levels.

At the very least, you should take a Vitamin D supplement if you’re deficient. I take some Vitamin D3 in supplement form, depending on my levels.

It's important to test and monitor your Vitamin D levels before and after supplementing with it.

The Best Herbs and Natural Supplements to Increase GDNF Levels in the Brain

23. Curcumin

Curcumin is the most heavily researched compound within turmeric, the spice that gives curry its yellow colour.  

It’s one of my favourite natural compounds for the brain.

It has been found to increase GDNF levels in the brain and protect against neurodegeneration.

A study found that curcumin increased GDNF levels in the brain of mice with a genetic predisposition to Alzheimer's disease. The study also found that curcumin improved cognitive function and reduced amyloid plaque buildup in the brain (18). 

Another study found that curcumin increased GDNF levels in the striatum of rats with Parkinson's disease. The study also found that curcumin improved motor function and protected against dopaminergic neuron loss (19). 

And a study published in the journal Behavioural Brain Research found that curcumin increased GDNF levels in the hippocampus and cortex of rats and that this increase was associated with improved cognitive function (20). 

Curcumin is included in the Optimal Energy supplement

Since curcumin is a fat soluble, it should be taken with a fatty meal.

 

24. Resveratrol

Resveratrol is a beneficial antioxidant and anti-inflammatory compound.

Many people know that it’s found in grapes, red wine, raspberries and dark chocolate.

Resveratrol is known to help prevent the development of neurodegenerative diseases.

And researchers are starting to understand why.

Resveratrol can increase BDNF, help restore the integrity of the blood-brain barrier, and support your mitochondria.

But it has also been found to protect against neurodegeneration by increasing GDNF levels in the brain.

Researchers found that resveratrol supplementation increased GDNF levels in the striatum of rats with Parkinson's disease, and that this increase was associated with improved motor function (21). 

Another study published in the Journal of Medicinal Food found that resveratrol supplementation increased GDNF levels in the hippocampus and cortex of rats, and that this increase was associated with improved cognitive function (22). 

Research also shows that resveratrol treatment increases GDNF levels in the hippocampus of rats, and that this increase was associated with reduced anxiety-like behavior (23). 

To consume enough resveratrol to increase GDNF, you’ll need to supplement with it.

Resveratrol is included in this supplement.

 

25. Creatine

Creatine is a naturally occurring amino acid that is involved in energy metabolism in the body. 

It’s found in some foods, particularly meat, eggs, and fish.

But it’s also available as a supplement. 

Athletes, bodybuilders, wrestlers, sprinters often take extra creatine to gain more muscle mass. It’s an incredibly well-researched supplement and safe to take regularly. 

There is also some research suggesting that creatine supplementation can increase the levels of GDNF.

In one study, researchers investigated the effects of creatine supplementation on GDNF levels in the brains of rats. 

The researchers found that creatine supplementation increased the levels of GDNF in the striatum, a brain region involved in motor function, and that this increase was associated with improved motor function in these rats (44). 

Another study looked at the effects of creatine supplementation on GDNF levels in the brains of mice with Parkinson's disease. 

The researchers found that creatine supplementation increased the levels of GDNF in the brains of these mice, as well as improved their motor function and reduced neurodegeneration (45). 

I don’t take it anymore, but creatine used to give me mental energy when I took it years ago.

 

26. Bacopa

Bacopa monnieri is a nootropic and medicinal herb used in traditional Ayurvedic medicine to enhance cognition.

In one study, researchers have investigated the effects of a standardized extract of Bacopa monnieri on GDNF levels in the brains.

The researchers found that treatment with Bacopa monnieri extract increased GDNF levels in the hippocampus, a brain region involved in learning and memory

The study also found that the extract improved cognitive function, suggesting a potential therapeutic benefit of Bacopa monnieri for cognitive disorders (49). 

Besides improving memory and cognition, I have found that bacopa is very relaxing and good at reducing anxiety and stress

So it’s a good option if you’re looking for something to increase GDNF and relieve anxiety at the same time.  

 

27. Lion’s Mane Mushroom

Hericium Erinaceus – better known as lion’s mane mushroom – is an edible mushroom with numerous health benefits. 

It’s another one of my favourite nootropic supplements for brain health because it reduces inflammation and has antioxidant effects. 

Researchers have investigated the effects of an extract of Lion's Mane Mushroom on GDNF levels in the brains of mice with Alzheimer's disease.

The researchers found that treatment with the Lion's Mane Mushroom extract increased GDNF levels in the hippocampus and cortex, two brain regions involved in learning and memory. 

The study also found that the extract improved cognitive function and reduced amyloid plaque deposition in these mice, suggesting a potential therapeutic benefit of Lion's Mane Mushroom for cognitive disorders (50). 

This lion’s mane mushroom supplement is the highest-quality that I could find. I spent a lot of time researching and looking into different sources because not all lion's mane supplements are high-quality and effective, and I settled on this one.

28. Ashwagandha

Ashwagandha (Withania sominifera) is a popular Indian herb that has been used for more than 3000 years. 

It’s sometimes called the “Indian Ginseng”.

It’s known as an “adaptogen”, which is a compound that balances the body and restores normal bodily functioning after chronic stress.

It is typically used to inhibit stress and anxiety, but it also affects cognitive function, energy levels, well-being and sleep quality.

Researchers have investigated the effects of Ashwagandha extract on GDNF levels in the brains of rats with Parkinson's disease. 

The researchers found that treatment with Ashwagandha extract increased GDNF levels in the brains of these rats, suggesting a potential neuroprotective effect (51). 

Ashwagandha is one of the main herbs I took to reduce stress and anxiety as I came off psychiatric medications.

 

29. N-Acetyl-Cysteine

N-Acetyl-Cysteine (NAC) is a modified form of the amino acid cysteine.  

It’s also the precursor to glutathione, your body’s master antioxidant.  

Nowadays, we’re exposed to so many environmental toxins, which cause oxidative stress in the body and deplete our reserves of cysteine and glutathione.  

But supplementing with NAC can increase and normalize your cysteine and glutathione levels, and this can combat and reduce oxidative stress in your brain.

In one study, researchers investigated the effects of NAC on GDNF levels in the brains of rats with ischemic stroke. The researchers found that treatment with NAC increased GDNF levels in the brains of these rats, improved their motor function and reduced their brain damage (52). 

Another study looked at the effects of NAC on motor function and dopamine neuron survival in a rat model of Parkinson's disease. 

The researchers found that NAC improved motor function and dopamine neuron survival in these rats, and that this was associated with increased levels of GDNF in the striatum, a brain region involved in motor function (54). 

On the other hand, another study investigated the effects of NAC on GDNF levels in the brains of mice with Parkinson's disease. 

The researchers found that treatment with NAC did not increase GDNF levels in the brains of these mice, but did improve motor function and reduce oxidative stress (53). 

These conflicting findings suggest that the effects of NAC on GDNF levels may vary depending on the specific context and type of neurological condition.

So while there is some preliminary research suggesting that NAC may increase GDNF levels in certain contexts, more research is needed to determine the specific mechanisms underlying these effects and to determine whether NAC has consistent effects on GDNF levels across different neurological conditions.

If you are interested in trying NAC, it is included in the Optimal Antiox supplement

Be sure to read this article all about the benefits of NAC.

 

30. Testosterone

Testosterone is a hormone that is primarily produced in the testicles in men and in the ovaries and adrenal glands in women. 

Studies suggest that testosterone can increase GDNF levels in the body.

Researchers found that testosterone increased GDNF levels in the brains of rats. The study involved exposing rats to testosterone for six days and measuring GDNF levels in the rats' brains. The researchers found that testosterone was associated with a significant increase in GDNF levels in the rats' brains compared to a control group (62). 

Another study found that testosterone increased GDNF levels in the testes of rats. The study involved exposing rats to testosterone for seven days and measuring GDNF levels in the rats' testes. The researchers found that testosterone was associated with a significant increase in GDNF levels in the rats' testes compared to a control group (63). 

When I was living in a moldy home, I suffered multiple concussions and doctors placed me on antidepressants

As a result, my testosterone plummeted. 

I was put on testosterone replacement therapy for almost one year to get my levels back to normal. And over that time, I saw a huge increase in my brain and mental health.

That's why it's so important to check your testosterone level regularly. Make sure you check both total testosterone and free testosterone. 

You can test your total and free levels here.

 

31. Estrogen

Estrogen is a hormone that is primarily produced in the ovaries in women and in smaller amounts in the testicles and adrenal glands in men. 

There is some evidence to suggest that estrogen has an effect on GDNF levels in the body.

For example, a study published in the journal BMC Neuroscience found that estrogen increased GDNF levels in the brains of rats. The study involved exposing rats to estrogen for four days and measuring GDNF levels in the rats' brains. The researchers found that estrogen was associated with a significant increase in GDNF levels in the rats' brains compared to a control group (64). 

Another study published in the journal Hormones and Behavior found that estrogen increased GDNF levels in the hippocampus of rats. The study involved exposing rats to estrogen for seven days and measuring GDNF levels in the rats' hippocampi. The researchers found that estrogen was associated with a significant increase in GDNF levels in the rats' hippocampi compared to a control group (65). 

I recommend both men and women get their hormone levels checked regularly, and then optimize them if they want to optimize their brain function and feel their best.

32. Ginseng

Ginseng is a popular herbal supplement that has been used for centuries in traditional medicine. 

There is some evidence suggesting that ginseng can have an effect on GDNF levels in the body.

For example, researchers found that ginseng increased GDNF levels in the brains of rats. The study involved exposing rats to ginseng for 14 days and measuring GDNF levels in the rats' brains. The researchers found that ginseng was associated with a significant increase in GDNF levels in the rats' brains compared to a control group (68). 

Another study found that ginseng increased GDNF levels in the hippocampus of rats. The study involved exposing rats to ginseng for 14 days and measuring GDNF levels in the rats' hippocampi. The researchers found that ginseng was associated with a significant increase in GDNF levels in the rats' hippocampi compared to a control group (69). 

Ginseng is one of my favourite herbal supplements for brain function and depression.

The best form of ginseng that I have personally benefited the most from is American Ginseng (Panax quinquefolius).

Years ago, I found that it improved my memory and cleared brain fog quite quickly. But I no longer need to take it.

The 28 Best Natural Supplements Proven to Reduce Anxiety and Stress

Research shows that most people prefer to take over-the-counter natural remedies to treat their anxiety instead of medication.

Perhaps you’re struggling with generalized anxiety, social anxiety, panic attacks, post-traumatic stress, OCD or a phobia…

The good news is that there are many natural supplements that can bring you relief and ease your chronic stress and anxiety.

And they are safe and don’t cause adverse side effects like anti-anxiety medicine.

This article lists the best natural supplements that are proven to reduce anxiety and stress.

These solutions are evidence-based and backed by research.

They have worked for me and for many other people.

It starts off with my top 10 personal favourites.

And then offers 18 other great options.

A silhouette of a person looking anxious, stressed and depressed.

My Top 10 Favourite Supplements to Reduce Anxiety and Stress

1. Theanine

Theanine is a unique amino acid found in tea. It has a number of mental health benefits.

It’s known to produce a calming effect on the brain by crossing the blood-brain barrier and increasing the production of GABA, serotonin and dopamine in the brain. Unlike prescription anti-anxiety medication, it does not cause sedation and drowsiness (72-75).

Researchers have found that theanine supplements significantly reduce stress and anxiety, lower heart rate, and increase mental relaxation (77-81, 83).

Studies have also shown that theanine increases alpha brain waves and deactivates the sympathetic “fight or flight” nervous system (76, 82).

And animal research shows that it reduces “circulating biomarkers of stress” in rats (84-85).

I sometimes take theanine alongside my morning coffee. It improves mood, helps with focus and cancels out the jitters of caffeine. It’s sort of like meditation in a pill.

This anti-anxiety supplement contains theanine, along with several natural compounds that have helped me manage my anxiety over the years.

 

2. Magnesium

Magnesium is a vital mineral that participates in more than 300 biochemical reactions in your body.

A bunch of magnesium-rich foods, including nuts, seeds, bananas. Magnesium supplementation can help reduce anxiety and stress.

It’s absolutely essential for the proper functioning of your nervous system and optimal neurotransmitter activity.

Nine different studies have found that magnesium supplements can reduce anxiety in humans and improve anxiety-related disorders (96-100).

And they start reducing anxiety quickly, often within one week (101).

Plenty of researchers have also found that magnesium has a relaxing effect in animals by calming the hypothalamic-pituitary adrenal (HPA) axis and activating GABA receptors. These are the same receptors activated by anti-anxiety medication (102-107).

Magnesium is included in this supplement.

 

3. Ashwagandha

Ashwagandha (Withania sominifera) is a popular Indian herb that has been used for more than 3000 years. It’s sometimes called the “Indian Ginseng”.

It’s known as an “adaptogen”, which is a compound that balances the body and restores normal bodily functioning after chronic stress.

A systematic review concluded that ashwagandha significantly reduces symptoms of stress and anxiety and is likely useful in the treatment of anxiety disorders (11).

In fact, two studies found that ashwagandha worked better than medication and psychotherapy at treating and reducing anxiety (12, 17, 19).

And other researchers have found that it reduces anxiety, decreases perceived stress, and improves the quality of life of people with anxiety disorders (13-16, 18).

Animal research also shows that ashwagandha causes anti-anxiety effects, reduces OCD-like behaviour and improves stress tolerance in rats (20-25).

So it’s a pretty amazing herb for anxiety.

But how does it work?

By increasing serotonin and GABA in the brain, and lowering cortisol levels by 25 per cent (26-29).

Ashwagandha is one of the herbs I took to help myself get off psychiatric medications.

That’s why it’s included in the Optimal Calm supplement.

 

4. Zinc

Zinc is an essential mineral for mental health, especially if you have chronic anxiety.

Like magnesium, it plays a key role in neurotransmission and nervous system functioning.

Researchers have found that zinc supplements can reduce symptoms of anxiety in both humans and animals (123-125).

I created the Optimal Zinc supplement so that you can ensure your zinc levels are optimal.

I previously wrote about the link between zinc and anxiety in this post.

Zinc can also stimulate your vagus nerve, which reduces anxiety.

 

5. Bacopa

Bacopa is an adaptogenic herb.

It’s commonly used to improve cognition and memory, but it’s also very good at reducing anxiety.

Researchers have found that bacopa supplements reduce stress, anxiety and cortisol levels in humans (89-91, 94).

In fact, one of the ways bacopa improves cognition is by simply reducing anxiety (95).

So if you have anxiety, and it negatively impacts your thinking, bacopa is a good choice.

Animal studies also show that bacopa reduces the biochemical effects of acute and chronic anxiety in rats. It does this by significantly increasing serotonin and dopamine levels and significantly reducing stress hormone levels (92-93).

I took a bacopa supplement for a while. I found that it made me really relaxed and sleepy. I eventually stopped taking it because it made me too sleepy. But if you have very severe anxiety, it can be very helpful.

6. Probiotics

Probiotics have also been shown to reduce anxiety.

One study found that a probiotic supplement containing Lactobacillus Rhamnosus significantly reduced anxiety and stress in humans (46).

And animal research shows that Lactobacillus Rhamnosus reduces stress and anxiety-like behaviour in mice (47-48).

Bifidobacterium Longum is another probiotic that can reduce anxiety.

Individuals that took it for 30 days experienced less anxiety and psychological distress, and also had lower cortisol levels (49).

Bifidobacterium Longum also reduces anxiety-like behaviour in animals by stimulating the vagus nerve (50-51).

Both Bifidobacterium Longum and Lactobacillus Rhamnosus are included in the Optimal Biotics supplement.

7. Inositol

Inositol is a naturally-occurring molecule found in nearly all plants and animals. It plays a key role in various biological processes.

Inositol powder. Inositol has been shown to help reduce stress and anxiety.

The brain has the highest concentration of inositol, where it plays an important role making neurotransmitters.

Inositol can be found in many foods, particularly fruit, especially cantaloupe and oranges.

But you need to supplement with it to reduce anxiety.

Researchers have found that taking an inositol supplement every day can significantly reduce anxiety in both adults and children. This includes a reduction in panic attacks and fewer symptoms of agoraphobia and obsessive-compulsive disorder (64-67).

In fact, research suggests that it’s as effective as an SSRI antidepressant in the treatment of anxiety and panic disorder (62).

And one study shows that it can reduce anxiety in people struggling with bulimia or binge eating (63).

Lots of animal research also shows that inositol reduces anxiety-like behaviour in rats (68-71).

It’s important to point out that the research suggests that you need to take high doses (12 to 18 grams daily) if you want to experience the anxiety-reducing benefits of inositol.

I took high doses of inositol powder when weening off psychiatric medication.

Check out my full post about inositol to learn more about the benefits.

Fun fact: Inositol is a white powder, so actors snort inositol instead of actual cocaine in television and movie scenes.

 

8. Valerian

Valerian (Valeriana officinalis) is an herb, and the root of the herb has traditionally been used to treat insomnia.

But it also can reduce anxiety.

Research shows that valerian root extract significantly reduces stress and anxiety (235-236).

Animal studies have also found that it reduces psychological stress and anxiety in rats and mice (259-265).

And in one study, Valerian demonstrated some anti-obsessive and anti-compulsive effects and therefore may help treat obsessive-compulsive disorder (234).

Scientists have collected a massive amount of research demonstrating that the compounds in Valerian naturally reduce stress and anxiety by:

As a result of this, it creates a calming effect similar to anti-anxiety drugs like Xanax and Valium.

This is why Valerian is often called “Nature’s Valium”.

Valerian is one of the first herbal remedies I took years ago to manage my anxiety at night and improve my sleep. It’s included in this anti-anxiety supplement.

Valerian supplements include the roots and stems of the plant.

But you can also take it as a tea or tincture if you want.

 

9. Cannabidiol (CBD)

Cannabidiol (CBD) is one of the active cannabinoids found in marijuana.

A glass of CBD oil. CDB oil has been shown to help reduce anxiety and stress.

Unlike tetrahydrocannabinol (THC), CBD isn’t psychoactive and doesn’t make you “high”.

But it can help treat a number of diseases because it reduces inflammation.

Research has found that CBD oil significantly reduces anxiety in both healthy individuals and patients with social anxiety disorder (3-4).

It also significantly reduces anxiety, distress and discomfort caused by public speaking (5).

Researchers also think it can help people with panic disorder, obsessive-compulsive disorder and post-traumatic stress disorder (2).

This is because studies show that CBD activates serotonin receptors in the brain, increases GABA levels, lowers activity in the amygdala, and increases activity in the prefrontal cortex (6-10).

I used to take this CBD oil and highly recommend it. It significantly reduced my stress, made me sleepy and knocked me out before bed.

Some people report that marijuana makes them anxious.

When I’ve smoked it in the past, it often made me anxious.

This is possibly because most marijuana has high levels of THC and lower levels of CBD.

Taking extra CBD may help.

One study found that CBD blocks the anxiety caused by THC (1).

 

10. Kava

Kava is a plant located in the western Pacific.

The root of the plant is used medicinally to treat anxiety and sleep disorders because it causes relaxation without impairing cognitive performance. Some people say it feels like drinking alcohol.

A meta-analysis concluded that kava can significantly reduce anxiety without very many side effects (30).

And numerous human studies show that kava can reduce all sorts of anxious symptoms, including tension, agitation, restlessness and phobias (32-34).

Researchers have compared a bunch of different herbal anti-anxiety remedies, and they found that kava is one of the most potent and effective options (35-36).

In fact, they think that kava should be a first-line treatment for anxiety because it’s so powerful and safe and works just as well as anti-anxiety medication (31, 37-38).

Studies even show that kava works similarly to benzodiazepines like Xanax by activating and strengthening GABA receptors in the brain (39-45).

I personally don’t take kava anymore because I get a weird reaction from it and I was able to confirm that I’m allergic to the plant.

But it works very well for many people, so that's why I'm including it in my top 10. 

 

Other Effective Anxiety-Reducing Supplements

11. Omega-3 Fatty Acids

Omega-3 fatty acids are essential fats that your body cannot produce itself, and they are absolutely necessary for the normal functioning of your brain and nervous system.

Numerous studies show that supplementing with omega-3 fatty acids significantly lowers inflammation and progressively reduces symptoms and feelings of anxiety (108-114).

Researchers have also found that supplementing with omega-3 fatty acids inhibits activation of the hypothalamic-pituitary adrenal (HPA) axis, which is involved in anxiety (108).

I recommend supplementing with krill oil, a special kind of fish oil that contains the essential omega-3 fatty acids.

I no longer take it. But when I did years ago, I would feel more anxious when I stopped taking it. I would actually notice the difference.

You can read more about the importance of omega-3 fatty acids here.

 

12. Chamomile

Chamomile plant. Chamomile has been shown to reduce stress and anxiety.

Chamomile is a medicinal herb that has been traditionally used for its calming and anti-inflammatory properties.

It contains essential oils and flavonoids that can help you relax.

Researchers have found that oral supplementation of chamomile significantly reduces anxiety and stress in patients with generalized anxiety (54-58).

Animal studies show that chamomile contains substances that act on the same parts of the brain as anti-anxiety drugs (52-53).

Apigenin, one of the main flavonoids in chamomile, reduces anxiety without sedation by enhancing GABA communication (59-61).

 

13. Passion Flower

Passion Flower represents a family of plants known as Passiflora.

There are about 500 known species of Passion Flower.

One species, Passiflora incarnata, has been shown to reduce anxiety and stress.

In one study, researchers found that Passiflora incarnata extract reduced generalized anxiety as much as a benzodiazepine. But it didn’t cause side effects that are common with anti-anxiety medication, such as cognitive impairment (213).

Two other studies show that supplementing with Passion Flower significantly reduces anxiety before surgery (214-215).

Animal research has found that it increases GABA, a neurotransmitter that reduces stress and anxiety (216-217).

Passion Flower is one of the first herbal remedies I took years ago to manage my anxiety. It’s included in this anti-anxiety supplement.

 

14. Lemon Balm

Lemon balm (Melissa officinalis) is a lemon-scented herb and tea known to reduce inflammation, lower cortisol and increase GABA levels in the brain.

Lemon balm (Melissa officinalis) plant. Lemon balm has been shown to reduce stress and anxiety.

As a result, it has a sedative effect, calming the nerves and relaxing the body.

Research shows that lemon balm extract significantly reduces anxiety and stress in humans (146-149).

In one study, researchers gave Cyracos, a standardized lemon balm extract, to individuals with anxiety disorders, and it significantly reduced their anxiety. As much as 95% of the subjects responded to the treatment, and 70% of them achieved full remission (145).

Animal studies also show that it reduces stress and anxiety in rats by reducing stress hormones and increasing serotonin and GABA. The effects are comparable to anti-anxiety medication (150-155).

Lemon balm is included in this anti-anxiety supplement

 

15. Rhodiola

Rhodiola, also known as golden root or arctic root, is a Traditional Chinese and Scandinavian herb.

It’s one of the most popular adaptogens used to increase physical and mental stamina.

Research shows that rhodiola supplementation significantly reduces anxiety and stress symptoms (86),

In one study, individuals with generalized anxiety disorder supplemented with rhodiola, and it significantly reduced their symptoms of anxiety (88).

Improvements can be seen within just three days of treatment (87).

I take rhodiola as needed. I find that it can improve mood and energy, especially after stressful periods of pushing myself too hard.

Rhodiola has a number of brain and mental health benefits. I previously wrote about it here if you’re interested in learning more.

16. Ginkgo Biloba

Ginkgo Biloba is a plant that has been used in China for thousands of years to treat a number of health problems.

It’s one of the top-selling natural supplements in the world, and it’s even a prescription herb in Germany.

It’s most commonly used to improve brain health because it increases blood flow to the brain and improves memory and attention in both healthy and unhealthy individuals.

But researchers have also found that it reduces anxiety and stress.

Two studies show that supplementing with Ginkgo Biloba significantly reduces anxiety compared to placebo (115-116).

This occurs in both elderly individuals with cognitive decline and younger people with generalized anxiety disorder (115-116).

And in healthy individuals, it reduces cortisol release during a stressful event (119).

Animal studies also show that Ginkgo Biloba has anti-stress and anti-anxiety effects in both mice and rats, without producing benzodiazepine-like side effects (117-118, 120-122).

Ginkgo Biloba is included in the Optimal Brain supplement

 

17. Vitamin B6

Vitamin B6 is a key nutrient that supports your entire nervous system.

It accomplishes this by playing a key role in the production of calming neurotransmitters in your brain, including serotonin and GABA.

A bunch of foods with Vitamin B6 in them, including pistachios, red meat, chicken, potatoes and bananas. Vitamin B6 supplementation can help reduce anxiety and stress.

Studies have found that Vitamin B6 supplements can reduce anxiety (126-128).

When I took antidepressants and benzodiazepines for my chronic anxiety, multiple functional and integrative doctors suggested I supplement with Vitamin B6.

This is because these medications can actually further deplete Vitamin B6, increasing anxiety in the long run.

If you take a medication to manage your anxiety, or simply have anxiety and want to manage it better, I recommend supplementing with Vitamin B6.

Vitamin B6 is included in the Optimal Calm supplement.

 

18. Vitamin C

Vitamin C is another way to reduce your anxiety and stress.  

Researchers have found that Vitamin C supplements significantly reduce stress and anxiety in humans and animals by limiting cortisol levels (129-136).

As you probably know, Vitamin C is found in fruits and vegetables such as green peppers, citrus fruits, tomatoes, cauliflower, Brussels sprouts, broccoli, and cabbage.

In addition to getting Vitamin C from fruits and vegetables, I recommend taking at least 100 mg of supplemental Vitamin C every day.

But based on my research and experience, if you want to reduce your stress and anxiety, you may have to take large doses of Vitamin C.

Two studies show that supplementing with a high dose (at least 3 grams) of Vitamin C reduces cortisol, psychological stress and anxiety (137-138).

I experimented with taking up to 10 grams of Vitamin C daily, and it definitely reduced my stress and anxiety when coming off several psychiatric medications.

That’s why it’s included in Optimal Calm.

 

19. Curcumin

Curcumin is the most heavily researched compound within turmeric, the spice that gives curry its yellow colour.

A bowl or turmeric spice. Curcumin is the main compound in turmeric that has been shown to reduce stress and anxiety.

Research shows that it can reduce anxiety in individuals with major depressive disorder (139-141).

One animal study found that it reduces anxious behavior in rats (142).

Curcumin is a good option is you struggle with chronic inflammation and both depression and anxiety.

In my experience, it doesn’t help as much if you only have anxiety.

But it’s still one of my favourite natural compounds for the brain and mental health.

 

20. Lion’s Mane Mushroom

Hericium Erinaceus – better known as lion’s mane mushroom – is an edible mushroom with numerous health benefits.

It’s another one of my favourite supplements for brain health because it reduces inflammation and has antioxidant effects.

One study found that it reduced anxiety in 30 women after 4 weeks of supplementation (143).

And an animal study showed that it reduces anxious behaviour in rats by increasing neurogenesis (144).

This lion’s mane mushroom supplement is the highest-quality that I could find. I spent a lot of time researching and looking into different sources because not all lion's mane supplements are high-quality and effective, and I settled on this one.

21. Holy Basil

Holy Basil (Ocimum sanctum) is an adaptogenic herb that supports the body’s stress response. 

It’s known to have calming and relaxing effects on the body and mind.

In one study, researchers found that OciBest, a whole plant extract of Holy Basil, significantly reduced symptoms of stress. It was 39 per cent more effective than placebo, and there were no adverse effects (156).

Another study showed that supplementing with Holy Basil significantly reduces stress and anxiety in people with generalized anxiety disorder (157).

It’s also been shown to reduce cortisol (158-159).

And there is plenty of animal research showing that Holy Basil reduces anxiety, stress and stress hormone levels in mice and rats. And the anti-anxiety and anti-stress effects are comparable to antidepressant drugs (160-164).

Holy Basil can be taken as a supplement, herbal tea, dried powder, or fresh leaf used in cooking.

 

22. Saffron

Saffron is a spice derived from the Crocus sativus plant.

It has a number of health benefits due to the medicinal compounds within it.

The saffron plant. Saffron has been shown to reduce anxiety and stress.

Safranal and Crocetin, two of the compounds within saffron, have been shown to stimulate GABA receptors and increase serotonin levels in the brain (165-166).

Because of this, researchers have found that supplementing with a saffron extract can reduce anxiety (167).

Several preclinical and clinical studies show that supplementing with saffron significantly reduces stress and anxiety in adults and youth without side effects (169-173).

And one study found that the aroma of saffron significantly reduces cortisol levels and symptoms of anxiety in women (168).

Animal research also demonstrates that saffron reduced anxiety-like behaviours in mice (174).

 

23. Sceletium Tortuosum

Sceletium tortuosum is a plant commonly found in South Africa.

It’s a psychoactive herb but it doesn’t cause hallucinations or lead to addiction.

It often used before stressful events because research shows that it reduces anxiety and stress.

Researchers have found that it reduces anxiety and stress in humans by decreasing activity in the amygdala and inhibiting the reuptake of serotonin (175).

Animal studies have also shown that reduces anxiety and stress hormones (176-179).

Zembrin is the patented form of Sceletium tortuosum often found in supplements.

 

24. Lavender

Lavender is often used in soap and shampoo because it smells nice.

A small bottle of Lavender oil surrounded by plants. Lavender reduces anxiety and stress.

But it also has a number of health benefits.

Lots of research shows that lavender significantly increases calmness, relieves restlessness and nervousness, and reduces emotional distress in people with anxiety disorders – without causing any unwanted side effects (180-183).

One study found that Silexan, an oral lavender oil capsule, is just as effective at reducing generalized anxiety as lorazepam, a common benzodiazepine. And it didn’t cause side effects or addiction like the anti-anxiety medication (184).

Tons of other studies show that inhaling the scent of lavender oil significantly reduces anxiety before exams, surgery and dental procedures (185-190).

And in two studies of women with postpartum depression, inhalation of lavender oil significantly decreased their anxiety and stress (191-192).

Unlike a lot of other natural compounds, scientists actually understand how lavender works – it decreases heart rate, blood pressure, body temperature and sweating; and it increases heart-rate variability and alpha brain waves (193-198).

Animal research also shows that it reduces anxiety in rats by increasing GABA (199-204).

As a result of all this, it has a powerful sedative effect on the nervous system, decreases the fight-or-flight responses, and relaxes the body.

Lavender essential oil can be taken orally, inhaled or applied to your skin.

Silexan is an oral lavander oil capsule commonly used in studies.

 

25. 5-Hydroxytryptophan (5-HTP)

5-Hydroxytryptophan (5-HTP) is a naturally-occurring amino acid and the precursor to serotonin, a neurotransmitter that can reduce stress and anxiety.

It easily crosses the blood-brain barrier and effectively increases the synthesis of serotonin in the brain (205).

Research shows that supplementing with 5-HTP significantly reduces anxiety by increasing serotonin levels (206-208, 212).

One study found that people with panic disorder who take 5-HTP experience a reduction in panic and the fewer panic attacks (209).

Not only does 5-HTP reduce anxiety by increasing serotonin; it’s also been shown to promote relaxation by increasing GABA and BDNF levels (210-211).

5-HTP in supplement form is extracted from the plant Griffonia simplicifolia.

26. Black Seed Oil

Nigella sativa, more commonly known as Black Cumin Seed, has been used as a natural remedy for more than 2000 years.

It’s surprising more people haven’t heard of it because it’s actually one of the top-ranked evidence-based herbal medicines.

Researchers have found that black seed oil reduces inflammation and anxiety without side effects (218-219).

Studies also show that it significantly reduces anxiety-like behaviour in animals by increasing GABA and serotonin levels (220-224).

 

27. Skullcap

Skullcap refers to two separate medicinal herbs – American skullcap (Scutellaria lateriflora) and Chinese skullcap (Scutellaria baicallensis).

Both herbs have been shown to reduce anxiety and stress.

A double blind, placebo-controlled study demonstrated that American skullcap can reduce anxiety in adults (225).

Other research has found that Chinese skullcap can reduce anxiety and treat stress-related disorders by reducing stress hormones and enhancing GABA receptor activity (226-228).

 

28. Gotu Kola

Gotu Kola (Centella Asiatica) is an herb with antioxidant and anti-inflammatory properties.

It has been used for centuries in Ayurvedic and traditional Chinese medicine to alleviate symptoms of anxiety.

Researchers have found that Gotu Kola significantly reduces anxiety, stress and depression in individuals with generalized anxiety disorder (229).

In one study, people that supplemented with Gotu Kola were less likely to be anxious and easily startled (230).

Animal research shows that lowers anxiety-like behaviour in rats by increasing GABA levels (231-233).

It's important to point out that the Gotu Kola plant soaks up heavy metals from the soil. So you need to find a high-quality, organic source that doesn’t contain heavy metals.

 

Bringing It All Together: Taking Them in Combination Is Better Than Individually

It’s important to note that taking a combination of the above options will provide the greatest relief from anxiety.

They have a synergistic effect, meaning they work better when taken together.

Here are a bunch of proven combinations that you should consider if you want to powerfully reduce your anxiety and stress:

  • Ashwagandha and Bacopa – In one study, researchers found that taking these herbs together worked significantly better than taking them alone (269).

  • Bacopa and Omega-3 Fatty Acids – Since Bacopa is fat soluble, it’s said that it works better when it’s taken with a meal that contains fat. And research backs this up. One study found that bacopa and fish oil are more therapeutic together (270).

  • Valerian and Lemon Balm – These two herbs are most often sold in combination with each other. And there’s good reasons why. Together, both of these plants significantly reduce anxiety, restlessness, concentration difficulties and impulsiveness in adults and children (272-273). Their both included in the Optimal Calm supplement.

  • Chamomile and Lavender – One study showed that the aroma of both chamomile and lavender was more effective at reducing symptoms of anxiety and stress than either of them alone (271).

  • L-Lysine and L-Arginine – These two amino acids aren’t even included in the list above because they aren’t effective at reducing anxiety and stress alone. But together, they have been shown to significantly reduce anxiety and decrease cortisol levels (274).

  • A lozenge containing 4 different herbal preparations (lavender oil, extracts from hops, lemon balm and oat) has been shown to reduce anxiety, increase relaxation and increase alpha brain waves (275).

If you’re looking for an all-in-one supplement, this anti-anxiety supplement includes several of the natural compounds listed above all in one capsule.
