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. Douglas Laboratories L-Tryptophan supports serotonin synthesis for healthy well-being and sleep.
