L-Tryptophan by Douglas Laboratories 60 VCaps

L-Tryptophan is an essential amino acid and a precursor for the syntesis 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.† This unique formula contains necessary cofactors to ensure the proper synthesis of Seratonin.
