Serotonin plays multiple functions in the body. It is also produced locally in the brain. It plays a significant role in the circulatory system as well. Serotonin in your stomach does not migrate to the brain. You cannot eat serotonin and have it end up in your brain. You can consume serotonin precursors, which are transported to the brain and used to produce serotonin locally. The body is very segmented, especially the central nervous system. The body can’t be interpreted as a chemical soup where all the chemicals are mingling with all the organs at the same levels.
