Product description
L-Tryptophan is an essential amino acid and a precursor for serotonin synthesis. Tryptophan crosses the blood-brain barrier and is converted to L-5-hydroxytryptophan (5-HTP), which in turn is converted into serotonin. Serotonin is an important neurotransmitter for the regulation of appetite, mood, and melatonin production.
