L-TRYPTOPHAN is an essential amino acid that serves as a precursor for
the sleep hormone melatonin as well as for niacin and serotonin. Serotonin is an
important neurotransmitter in the central nervous system that has a calming effect and
helps modulates mood, sleep, and metabolism. L-Tryptophan is the least abundant
amino acid in the American diet. Even a person on a high protein diet generally gets
less than 1.5 grams a day. Supplementary L-Tryptophan may provide nutritional support
for restful sleep and a positive mood
