Serotonin + Gut-Health

What is Serotonin?

Serotonin functions as both a neurotransmitter and a hormone. It’s often called the ‘feel good’ hormone. It’s responsible for regulating our mood, supporting normal bowel movements and good sleep. When serotonin is imbalanced, we can experience:

  • anxiety

  • depression

  • poor sleep

  • irritability

  • headaches

  • panic attacks

  • digestive problems

How our Gut-Health Affects Serotonin

Only about 2% of serotonin is found in the brain, and about 95% is found in our gut. This is a pretty big deal, because this means that when our microbiome is balanced and healthy, it can produce wonderful amounts of serotonin (and other neurotransmitters like dopamine and GABA!).

However, if there are high levels of pathogenic bacterial strains in the gut, the body may produce less of these mood-modulating neurotransmitters and more stress hormones. Gut-healing is one of the main focuses in my practice, because our gut-health is such a vital piece of our mood-health.


“Serotonin and other neurotransmitters travel from the gut to the brain via the vagus nerve. This is the body’s longest nerve that emerges directly from the brain. Chemical signals travel both from the gut to the brain and vice versa. Because of this, those with gut issues are at a higher risk of mood imbalances, anxiety, and depression.” -Dr. Amy Meyers, amymyersmd.com


5 Ways to Support Balanced Serotonin:


Food Sources

Tryptophan is the amino-acid precursor to serotonin. So include foods rich in tryptophan like:

  • turkey

  • fish

  • chicken

  • pumpkin seeds

  • apples

  • bananas


Sunlight

Getting sunlight exposure daily (try eating your breakfast or lunch outside everyday!) also really supports serotonin levels. Studies have shown that the body’s serotonin levels increase with sunlight exposure- which I think it pretty darn cool!


Movement

Daily movement like walking, yoga or dancing are all easy ways to modulate our body’s production of serotonin, because exercise helps boost serotonin and endorphin production.


Gut Lining-Support

Gut-lining support is important because the lining of the intestines are vital for nutrient-absorption. Without absorption we aren’t able to use the important mood-boosting foods and nutrients we eat. I like to include foods rich in l-glutamine to help heal and seal the intestinal lining. Here are a few favorites:

  • Bone Broth

  • Collagen

  • Gelatin

  • L-Glutamine powder like ‘Leaky Gut Revive’ (you can purchase below)

Probiotic-Rich Foods

Finally, balancing our microbiome by caring for our gut (think probiotics and probiotic-rich fermented foods) is key to providing the right balance of beneficial serotonin-supporting bacteria. Consider taking a soil-based probiotic like MegaSpore (purchase below) and adding 1 serving a day of these probiotic-rich foods:

  • Kimchi

  • Kombucha

  • Organic Miso

  • Sauerkraut (Refrigerated)

  • Raw Cacao nibs


Balancing our moods can be as simple as balancing our gut-health! If you would like to learn how to optimize your own moods, just book with me here!
