14 Powerful Ways to Form New Synapses in the Brain

Over the years, I’ve taken several psychiatric drugs, drank too much alcohol, and had numerous concussions – sometimes, all at once. 

In other words, my brain has taken quite the beating. 

Researchers used to think that if you damaged your brain like I did, you simply had to live with it.

But that’s no longer true. 

They now know the brain is plastic and flexible, and it can heal and recover.

You’re not stuck with the brain you have. 

You can actually change and improve it.

One way your brain repairs itself is through a process called synaptogenesis.

Synaptogenesis is the formation of new synapses in the brain.

Synapses are the connecting points between your 100 billion brain cells. You have trillions of synapses in your brain, and your brain cells communicate with one another across them (79). 

The deterioration and loss of synapses is linked to a number of neurodegenerative diseases and mental health disorders, including Alzheimer's disease, depression, poor learning and memory, intellectual impairment and other cognitive deficits (83-87). 

The good news is that researchers now know that synaptogenesis occurs in the brain throughout our entire lives (81-82). 

And there are a number of ways you can support synaptogenesis, promote the formation of new brain synapses and increase brain synapses. 

Below are 15 ways to do that.

Following these strategies can improve your mood, learning, memory and cognition.

Picture of brain and synapses.

1. Omega-3 Fatty Acids, Uridine and Choline

The formation of synapses depends on sufficient brain levels of three key nutrients – uridine, omega-3 fatty acids, and choline. These nutrients are synergistic, and if you take them taken together, they accelerate the formation of new synapses in the brain (66-67, 75-78). 

Unfortunately, most people nowadays don’t get enough of these essential nutrients through their diet because very few foods in the Western diet actually contain them.

In fact, the uridine in food is not bioavailable, and no food has been shown to increase plasma levels of uridine (1).

Picture of salmon and walnuts. Salmon and walnuts and rich in omega-3 fatty acids, which have been shown to form new brain synapses.

That’s why I now take this uridine monophosphate supplement sublingually to support the long-term health of my brain. 

At the same time, I take this krill oil supplement and the Optimal Brain supplement, which includes CDP-Choline and Alpha GPC (two high-quality sources of choline). This ensures my brain is getting enough of omega-3 fatty acids and choline.

Several researchers have concluded that supplementing with all three nutrients can increase synaptic formation, increase brain synapses, and improve cognition, learning and memory, particularly in people with Alzheimer's disease (68-74). 

Besides supplementation, I still encourage people to eat foods that contain omega-3 fatty acids and choline. 

The best way to get omega-3 fatty acids from food is by eating more cold-water fish such as salmon, black cod, sablefish, sardines and herring. And the best food sources of choline include grass-fed beef liver and egg yolks. These foods are included in my Free Grocery Shopping Guide for Optimal Brain Health.

Taking uridine, choline and omega-3 fatty acids together can also promote the regeneration of myelin.

2. Low Level Laser Therapy

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.

Most doctors don't know about LLLT; but not every doctor.

Man wearing LLLT helmet and using the Vielight device. LLLT and Vielight devices can help form new synapses in the brain.

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

One way that LLLT may help the brain is by encouraging synaptogenesis (12-15). 

Researchers have found that LLLT treatment significantly stimulates the synthesis of synapsin-1 (a marker for synaptogenesis) and increases synaptogenesis in the cortex (16-17). 

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

I use this device and shine the red and infrared light directly on my forehead. 

I also use the Vielight 810, which is an intranasal device with 810 nm of near infrared light (If you decide to try the Vielight, you can use the coupon code JORDANFALLIS for a 10% discount).

LLLT can also support mitochondria function, reduce brain fog, and increase blood flow to the brain

3. Bacopa

Bacopa monniera is an adaptogenic herb with cognitive-enhancing effects.

Several studies show that it improves cognition, learning and memory by strengthening communications between brain cells. Both healthy and elderly people who take the herb experience improved attention, learning and memory (2-5). 

Researchers believe these improvements are because bacopa increases brain synapses and increases specific neuromolecular mechanisms that encourage and enhance synaptogenesis (18). 

You can get bacopa through Amazon.

4. Exercise

Exercise is one of the best ways to promote the formation of new synapses.

Researchers have found repeatedly that physical activity encourages synaptogenesis and increases brain synapses (32-33). 

Exercise also increases blood flow to the brain, promotes the regeneration of myelin, and can help reverse brain damage and cognitive decline

So not surprisingly, many brain health experts recommend exercise as 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.

5. Magnesium Threonate

Magnesium is a vital mineral that participates in more than 300 biochemical reactions in your body, including neurotransmitter and hormonal activity, which can have a huge effect on your brain function.

Researchers have found that increasing magnesium levels in the brain improves learning and memory by promoting synaptogenesis and increasing brain synapses (25-26). 

One study concluded that magnesium threonate increases the number of synaptic connections between brain cells and boosts the density of synapses (27). 

Magnesium rich foods, including spinach, avocados, bananas, almonds. Magnesium helps the brain form new synapses.

Unfortunately, lot of people are deficient in magnesium today (6-8).

But there are a number of ways you can make sure you’re consuming enough. 

First, make sure you’re eating magnesium-rich foods 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 Brain Health.

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

But I also recommend a high-quality magnesium supplement. 

Magnesium threonate is the best form of magnesium for increasing brain magnesium levels and forming new synapses. 

I currently take this magnesium threonate supplement before bed.

Since most people are deficient, magnesium is one of the three supplements that I think everyone should be taking.

Magnesium can also help repair a leaky blood-brain barrier.

6. Intermittent Fasting

Fasting allows your digestive system to take a break and triggers a number of hormones that boost your body’s ability to repair itself.

On most days, I don’t eat breakfast at all, and then "break my fast" by eating my first meal of the day around 2 or 3 p.m. That means I eat all my food for the day within an 8-hour window.

There are many health benefits to doing this.

It can improve mitochondrial function, reduce brain fog, and help protect you from dementia

And researchers have also found that fasting can trigger and enhance synaptogenesis (28-31). 

The best way to start fasting is simply 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. 

7. 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 herbal supplements in the world, and it’s even a prescription herb in Germany.

It’s most commonly used to improve brain health because it’s been shown to increase brain blood flow and improve memory and attention in both healthy and unhealthy individuals. It even reduces the risk of dementia and Alzheimer’s disease and may also improve mood and mental energy (34).

Researchers have also discovered that it stimulates synaptogenesis and increases brain synapses (35). 

Ginkgo Biloba is included in the Optimal Brain supplement.

8. Motor Learning

Motor learning is essentially when you learn something new that involves movement.

Complex processes occur in the brain in response to practicing or experiencing the new motor skill.

This results in changes to the central nervous system, which allows you to produce the movement again in the future.

Researchers have found that motor learning triggers synaptogenesis and generates new synapses in the cerebellar cortex of the brain (36-39). 

Some activities that involve motor learning include learning how to play the piano, climbing trees, juggling, and playing table tennis. 

When you engage in these activities, motor learning occurs, and you form new synapses in order to learn and solidify the new skill. 

9. Resveratrol

Picture of grapes. Grapes are rich in resveratrol, an antioxidant than help you form new synapses in your brain.

Resveratrol is a beneficial antioxidant and anti-inflammatory compound 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 help restore the integrity of the blood-brain barrier, support your mitochondria, and increase blood flow to the brain. But it can also increase synaptogenesis.

Research shows the resveratrol promotes and enhances synaptogenesis (23-24). 

I take this resveratrol supplement to support the long-term health of my brain. I don't take it every day, just every so often. You can get it here or here.

10. Piracetam

Piracetam is a nootropic (cognitive-enhancing) supplement. It provides a mild boost to brain function and has a long history of being used to treat cognitive impairment in Europe, Asia and South America. 

According to researchers, one way it improves cognition is by enhancing synaptogenesis and increasing brain synapses (9-10). 

One study found that rats treated with piracetam had a higher number of synapses than rats not treated with piracetam (11). 

Here is a good piracetam supplement from a reliable brand. I used to take it regularly but not anymore.

Phenylpiracetam is an advanced version of piracetam and I found it to be more effective. It also has impressive anti-anxiety and antidepressant effects. You can get it here.

Both piracetam and phenylpiracetam work best if you take them with a source of choline, either CDP-Choline or Alpha GPC.

Both CDP-Choline and Alpha GPC are included in the Optimal Brain supplement

11. Quercetin

Quercetin is a bioflavonoid found in fruits and vegetables. It is one of the most widely consumed flavonoids in the human diet. 

Quercetin has potent antioxidant action and is “neuroactive”, meaning it can affect brain function. 

As a result, it can protect brain cells from oxidative stress and inhibit the pro-inflammatory molecules that are associated with many progressive brain disorders (45-46). 

Researchers have also found that it stimulates synaptogenesis (48). 

Red apples, onions and tomatoes have the high levels of quercetin. But you can also supplement with it if you want. 

It’s interesting to note that quercetin increases the absorption of resveratrol, so it’s a good idea to take them both together if you want to increase synaptogenesis and form new brain synapses (47).

12. Intranasal Insulin

Insulin is one of the hormones that significantly affects brain function.

It has a number of important functions in the central nervous system, and researchers have found that it passes the blood-brain barrier and acts on insulin receptors directly within the brain.

In a new therapeutic approach, commercially-available insulin (Novalin R) is prepared and added to nasal spray bottles - like these ones - and sprayed and inhaled through the nose to support brain and mental health.

Intranasal insulin has been reported to significantly enhance learning and memory, increase mental energy, reduce brain fog, improve mood, and lower anxiety and stress levels.

One possible mechanism is by increasing synaptogenesis.

Brain insulin receptors are found primarily in synapses, and insulin signaling contributes to synaptogenesis (19-21). 

And the disruption of insulin action in the brain leads to impairment of synaptogenesis (22). 

If you’re interested in learning more about intranasal insulin, I previously wrote a full article about it here.

13. Progesterone

Progesterone is a natural steroid and sex hormone involved in the menstrual cycle and pregnancy.

It has a variety of important functions in the body, and even plays an important role in brain function. 

Research shows that progesterone supports the normal development of brain cells and protects them from damage (40).

But many researchers have also found that progesterone promotes synaptogenesis (41-43). 

In addition to its role as a natural hormone, progesterone can be taken as a medication, usually by women during menopause as part of their hormone replacement therapy. 

14. Antioxidant Nutrients

Some nutrients have antioxidant effects in the body, and not consuming enough of them can reduce your rate of synaptogenesis. 

Research shows that “synaptic membrane synthesis” depends on sufficient dietary intake of Vitamin C, Vitamin E, and the mineral selenium (64). 

A bunch of antioxidant-rich fruits and vegetables in heart-shaped bowls. Antioxidants can helps the brain form new synaptic connections.

One study found that synaptogenesis was significantly enhanced by supplementing with omega-3 fatty acids, uridine, Vitamin C, Vitamin E, and selenium. But it wasn’t enhanced as much with omega-3 fatty acids and uridine alone, suggesting that Vitamin C, Vitamin E, and selenium play a key role in synaptogenesis (65). 

I get these antioxidant nutrients from a number of sources. 

In addition to getting Vitamin C from fruits and vegetables, I take at least 500 mg of supplemental Vitamin C every day. At one point, I was actually taking up to 10 grams of Vitamin C every day as an experiment, but that’s not necessary unless you find it really helps you.

For selenium, I make sure I eat brazil nuts regularly, as they are the richest source. But I also take some extra selenomethionine, which is the most absorbable form of selenium. 

For Vitamin E, good food sources include almonds, spinach, sweet potatoes, avocados, olive oil, sunflower seeds and butternut squash. It’s also included in the Optimal Antiox supplement.

Besides increasing synaptogenesis, antioxidants can also protect your brain from alcohol and help reverse brain damage

15. BONUS: 4 Things to Avoid

It’s not just what you do, but also what you avoid that can impact your rate of synaptogenesis. 

Researchers have found that certain compounds can impair synaptogenesis and inhibit the formation of new synapses in the brain. 

So besides trying to implement the 14 steps above, you should also try to avoid:

  • Bisphenol A – This compound is found in plastic bottles and containers, food and beverage cans, and other common consumer products, such as CDs, DVDs and sales receipts. Researchers have found that it impairs synaptogenesis in the brain (49). That’s why I recommend you only eat and drink out of glass, ceramic and stainless steel. Avoid all canned food and plastic containers. BPA-free plastic isn’t much better for you and can still disrupt hormonal health.

  • Lead – Lead is a heavy metal that can accumulate in the body and negatively affect brain function. Research shows that lead exposure can interfere with the formation of brain synapses (55-59). So it’s definitely a good idea to reduce your exposure to sources of lead. One way is by using an infrared sauna regularly.

  • Gabapentin – Gabapentin is a medication used to treat epilepsy, neuropathic pain, hot flashes, and restless legs syndrome. Researchers have found that it halts the formation of new synapses (80).

  • Stress – Chronic stress decreases synaptogenesis and decreases the number of synapse connections (88-89). Here are 20 ways to lower cortisol, your body’s main stress hormone. These two biofeedback devices are my favourite ways to reduce stress.

25 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 25 steps below and naturally increase your oxytocin levels yourself.

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. I personally use this lamp.

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

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 at least 500 mg of Vitamin C every day.

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

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

I now take this magnesium threonate supplement before bed. It’s the best form of magnesium for the brain. 

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 Zinc 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 this coffee doesn’t. I usually drink one cup of it 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 Kicking Horse 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). 

This anti-anxiety supplement includes chamomile, along with a number of other natural compounds that have helped me manage my stress and anxiety over the years.

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 on Amazon.

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 get 500 mcg of melatonin here on Amazon.

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, here are some other actions you can take to naturally produce more melatonin:

  • Expose your eyes to sun in the morning.

  • Blue light significantly suppresses your body’s production of melatonin, leading to disrupted sleep patterns and abnormal functioning of your nervous system. You can read more about the problem with getting too much blue light here. As soon as it’s dark outside, you should avoid sources of blue light. Turn off household lights, get red light bulbs, install Iris on your computer and wear glasses that block out blue light. I wear these glasses. They block out blue light in your environment.

  • Sleep in a dark environment. Completely black out your room with curtains and wear a sleep mask overnight. Sleeping with lights on in your room decreases neurogenesis and impairs cognitive performance (276). If you need to have light in your room (nightlight or alarm clock), it’s better to have red, orange or amber lighting rather than blue.

  • Melatonin secretion can be disrupted by EMF exposure, so turn off cellphones, Wi-Fi and other electrical devices while you sleep.

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 experimented with this 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. Here is the Clary Sage Oil that I took. 

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.

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

14. 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. :)

15. 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

16. 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 this acupuncture mat at home to relax before bed.

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

17. 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.

18. 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. 

19. 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! :)

20. 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). 

If you're interested in yoga, I recommend checking out Kalimukti. They offer tailored online yoga classes taught by qualified practitioners, allowing you to practice whenever and wherever you want.

21. 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. 

22. 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.

23. 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). 

New 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

24. 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

25. 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).
