Serotonin is a neurotransmitter that affects most brain cells. Related to numerous functions, including emotions, moods, sleep, memory and appetite, serotonin also affects the muscles, as well as the body's endocrine and cardiovascular systems. When the body is functioning normally, tryptophan, which is an amino acid, converts to 5-hydroxytryptophan, which converts to serotonin. Your doctor can order tests to determine whether or not you have low serotonin levels and can advise you on treatments.
