L-Tryptophan is an essential amino acid that serves as a precursor for the sleep hormone melatonin, for niacin and serotonin. Serotonin, an important neurotransmitter in the central nervous system, has a calming effect and plays a role in anger, aggression, mood, sleep, sexuality and appetite.‡

L-Tryptophan is the least abundant amino acid in the American diet. Even people on high protein diets generally get less than 1.5 grams daily. Supplementary L-Tryptophan provides nutritional support for restful sleep and positive mood.‡

TryptoPure® is produced by fermentation from vegetable sources, a process that yields 99%-100% pure, pharmaceutical grade L-Tryptophan. Manufactured in a pharmaceutical facility in Japan.‡
