When people think about serotonin, they usually think about the brain. But here's something fascinating: around 90–95% of your body's serotonin is actually produced in the gut by specialised cells called enterochromaffin (EC) cells.
These remarkable cells are scattered throughout the lining of your intestines. They act like tiny sensors, constantly sampling what passes through your digestive tract. When they detect nutrients, beneficial microbes, or even mechanical stretching from food moving through the bowel, they release serotonin.
In the gut, serotonin isn't there to make you feel happy. Instead, it helps regulate bowel movements, supports healthy gut motility, communicates with the nervous system, influences nausea, and plays an important role in the ongoing conversation between your gut and your brain. Healthy EC cells contribute to healthy digestion, while also influencing mood, sleep and overall wellbeing through the gut-brain axis.
So, how do you look after them?
The answer isn't a serotonin supplement. It's creating an environment where these cells can thrive.
Support your enterochromaffin cells by:
Eating a diverse range of colourful, fibre-rich whole foods to nourish your gut microbiome.
Looking after beneficial gut bacteria, as their fermentation products (particularly short-chain fatty acids) help maintain a healthy intestinal lining.
Ensuring regular bowel movements so waste products don't linger unnecessarily in the colon.
Managing chronic stress, which can disrupt gut signalling and serotonin regulation.
Prioritising quality sleep, as the gut and nervous system are closely connected.
Supporting overall digestive health, including healthy stomach acid, bile flow and intestinal barrier function.
Addressing digestive imbalances, such as infections or overgrowths, with appropriate guidance when necessary.
At Bottoms Up Colonics, we see every day how supporting the gut can positively influence how people feel. Not just physically, but mentally and emotionally too.
Rojas colon hydrotherapy and our trained therapists help you to optimise the gut environment, promote healthy bowel function and support digestive wellbeing to help create the conditions in which your gut, microbiome and enterochromaffin cells can function at their best.
After all, a healthy gut doesn't just digest food. It communicates with your entire body.
