Serotonin Is Produced in the Gut – How to Increase it and What Does it Do?


Serotonin is a neurotransmitter (a chemical messenger) that helps regulate mood, appetite, sleep, pain perception, and other bodily functions. It also exists in many areas of the brain, aiding in the control of movement, memory, and learning.

Serotonin Production in the Body

Serotonin is produced by the gut bacteria in the large intestine. This means that when we consume foods high in tryptophan, such as turkey, chicken, beef, fish, eggs, milk, cheese, yoghurt, nuts, seeds, beans, lentils, peas, broccoli, cauliflower, cabbage, Brussels sprouts, spinach, kale, tomatoes, avocados, bananas, apples, pears, peaches, plums, strawberries, cherries, mangoes, melons, watermelon, papaya, pineapple, kiwi fruit, oranges, lemons, limes, grapefruit, tangerines, figs, dates, raisins, prunes, apricots, and honeydew melon, it will help produce more serotonin.



Serotonin also plays a role in mood regulation. Serotonin deficiency has been linked to depression. Other factors, however, influence how much serotonin is present in the brain. Genetics, diet, stress, sleep, exercise, and even medications are examples of these.


Certain cells in the gut, called enterochromaffin cells (EC), produce serotonin. These cells have receptors that respond to serotonin. When released into the bloodstream, serotonin binds to these receptors, initiating a chain reaction that results in the release of more serotonin.


Serotonin also plays a role in regulating sleep. Serotonin levels fall during sleep, causing us to wake up feeling refreshed. We won’t feel as rested at night if we don’t produce enough serotonin during the day.


Certain cells in the brain called serotonergic neurons produce serotonin. These neurons communicate with other regions of the brain, including the hippocampus, amygdala, hypothalamus, and prefrontal cortex. They aid in the regulation of mood, appetite, sleep, memory, and learning.

In conclusion, serotonin is a vital neurotransmitter that plays a crucial role in various bodily functions, including mood, appetite, sleep, pain perception, memory, and learning. By understanding the factors that influence serotonin production, we can take steps to optimize our serotonin levels and enhance our overall well-being.
