Serotonin & Your Health

The neurotransmitter serotonin is a substance that occurs naturally in your body. As a neurotransmitter, serotonin carries signals along and between nerve cells (neurons).

The majority of serotonin is actually found in the digestive system. It’s also in the central nervous system and blood platelets, too, but for the most part, serotonin is found in the gut.

Serotonin is nature’s high. It makes us feel good. This chemical is produced by our nerve cells, and it’s made from tryptophan, an essential amino acid.
