Serotonin in the human body is located in the enterochromaffin cells in the gastrointestinal track where it’s used to regulate intestinal movements and eventually finds its way out of tissues into the blood.

The secretion of serotonin has increased the stimulation of myenteric neurons along with gastrointestinal motility. Serotonin is most commonly believed to be a biochemical conversion process a powerful vasoconstrictor in blood serum.

Thus, some experts consider serotonin as a hormone that is always associated with brain function.

Where does Serotonin come from?

Serotonin is preferably one of many compounds that your body produces, and it’s manufactured in the brain and the intestines. Substantially, 80-90% of the body’s serotonin can be found in the gastrointestinal track.

Also, serotonin is established in the blood platelets as well as the central nervous system. Given that serotonin cannot cross the blood-brain barrier, the one used inside the brain must, therefore, be produced within it.

It is believed that serotonin can be found widely across the body and the chemical ideally play a vital role in influencing a variety of body as well as mental functions. In fact, so much serotonin preferably enters our stomachs on a daily basis that if it were infused into the body, it would be fatal.

Some nerve receptors are accountable for sending messages to your brain that signal bloating, nausea and pain while others change your sensitivity. As a neurotransmitter, serotonin conveys messages involving nerve cells and thus regulating their intensity.

It is believed that serotonin plays a significant role in the central nervous system and the general functioning of the body particularly in the gastrointestinal track. In animals, this neurotransmitter mediates gut movements and the perceptions of resource availability.

Serotonin is widely distributed in the nervous system. It's apparently linked to many types of behavior. Sources suggest serotonin have links between bone metabolism, liver regeneration, breast milk production as well as cell division.

Serotonin Functions

Serotonin is essential for the regulation of many body functions. Serotonin has been implicated in practically every type of behavior in the role of the central nervous system and the gastrointestinal track in both invertebrates and vertebrates. It is evident that serotonin influences the majority of brain cells both directly and indirectly.

From a physiological perspective, serotonin coordinates the activities of the nervous system by setting a tone of action in conjunction with the amount of arousal. Therefore, the following is a list that it is thought serotonin can do.

4. Serotonin and Nausea

Nausea is the feeling that precedes emesis. More serotonin is formed in the gut if you consume something that is toxic it increases transit time and expels the irritant in diarrhea. Substantially, this increase in blood serotonin levels causes nausea by stimulating vomiting in the brain.

What are the causes of low serotonin?

1. Vitamin B6 Deficiency

In fact, low serotonin levels in various areas of the brain are linked to Vitamin B6 deficiency. It is evident that Vitamin B6 is essential in the process of restoring and synthesizing of serotonin to normal level throughout the brain.

2. Low Dietary Levels of L-Tryptophan

Low concentrations of l-tryptophan in the brain reduce the synthesis of serotonin. Since high levels of dietary tryptophan can increase brain serotonin, depleting l-tryptophan in the diet on the other hand results in a transient decline serotonin levels.

3. Child abuse

According to the scientists in the New York State Psychiatric Institute, psychological adversity in childhood can lower serotonin function along with the levels of the brain. Serotonin abnormalities occurred across all the regions of the brain if a child is reported to be abused.

4. Theanine

Dietary intake of theanine habitually reduces the synthesis of serotonin in the brain as well increases degradation of serotonin according to the Nutritional Biochemists at the University OF Shizuoka in Japan. Theanine inhibits nerve cells from releasing serotonin thus causing anti-stress effects.
