More Info

The essential amino acid l-tryptophan helps support relaxation, restful sleep, and positive mood. It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response and sleep/wake cycles. l-Tryptophan also supports immune functions because it is the body’s precursor to the kynurenines that regulate immunity. If needed, l-tryptophan converts to niacin in the body, which supports circulation, a healthy nervous system, the metabolism of food, and the production of hydrochloric acid for the digestive system. Source Naturals l-TRYPTOPHAN is extremely pure and is regularly tested to ensure the highest standards of quality.*

About Source Naturals

Source Naturals® was created in 1982 by C.E.O. Ira Goldberg to support each individual's potential to enjoy optimal health. At that time, the kind of nutritional formulations he envisioned—for the maintenance of well-being and the enhancement of life–simply didn't exist. The idea of combining many nutrients, herbs and nutraceuticals in one formulation, though common today, was then a rarity.
