L-tryptophan, or 5-HTP, is an essential amino acid that increases the production of serotonin in the central nervous system. Serotonin is an important neurotransmitter that regulates mood, appetite and sleep, and is often used to treat cases of depression or anxiety.
Thus, l-tryptophan can be used as a food supplement to help treat stress and hyperactivity in children, as well as to treat mild to moderate sleep disorders or depression in adults. Often, l-tryptophan can even be found in the blending of some remedies for depression and in the formula of some baby powder.
