Serotonin is manufactured in the brain and the intestines.
1 Serotonin is created by a biochemical conversion process. 2  Serotonin is manufactured in the brain and the intestines. 3  The majority of the body's serotonin, between 80-90%, can be found in the gastrointestinal tract. 4  Serotonin that is used inside the brain must be produced within it. Although serotonin is well known as a brain neurotransmitter, it is estimated that 90 percent of the body's serotonin is made in the digestive tract. In fact, altered levels of this peripheral serotonin have been linked to diseases such as irritable bowel syndrome, cardiovascular disease, and osteoporosis. Serotonin is manufactured in the brain and the intestines. The majority of the body's serotonin, between 80-90%, can be found in the gastrointestinal (GI) tract. It can also be found in the blood platelets and the central nervous system (CNS). Serotonin is an essential neurotransmitter responsible for regulating many body and brain activities. Though people associate serotonin only with the brain due to its role as a neurotransmitter, the brain only synthesizes and houses about 5 percent of the body's supply of serotonin. The small intestine produces the rest, and this serotonin never finds its way to the brain; rather, it plays other roles in the body. 1 Serotonin is manufactured in the brain and the intestines. 2  The majority of the body's serotonin, between 80-90%, can be found in the gastrointestinal tract. 3  Serotonin that is used inside the brain must be produced within it. 1. Seroton in acts as a ne urotransmitter, a type of chemical that helps relay signals from one area of the brain to another. Although serotonin is manufactured in the brain, where it performs its primary functions, some 90% of our serotonin supply is found in the digestive tract and in blood platelets. 1 Bowel function. 2  Most of the body's serotonin is found in the gastrointestinal tract where it regulates bowel function and movements. 3  It also plays a part in reducing the appetite while consuming a meal. 4  Mood. 5  It is most well know for its role in the brain where it plays a major part in mood, anxiety and happiness. Neurons produce serotonin in the brain. The serotonin in these two areas are distinct. That is, the serotonin from the intestine cannot go to the brain because of the blood-brain barrier, which the body uses to protect the brain from toxins.
