Brain serotonin precursor; supports a sense of calmness and restful sleep‡
L-Tryptophan is an essential amino acid and a precursor for the synthesis of serotonin. 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 necessary for the regulation of appetite, mood, and melatonin production.‡
L-Tryptophan, provided by Douglas Laboratories, supplies 1000 mg of pure L-Tryptophan plus other synergistic cofactors in two vegetarian capsules.
