The essential amino acid L-tryptophan helps support relaxation, restful sleep, and positive mood. L-tryptophan plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response and sleep/wake cycles. L-tryptophan supports immune functions because it is the body's precursor to the kynurenines that regulate immunity. L-tryptophan can convert 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. Suggested use is 1 capsule three times daily, between meals and preferably with fruit juice. To support restful sleep, take an additional 3 capsules before bed. The product contains no yeast, dairy, egg, gluten, soy or wheat, and no preservatives, or artificial color, flavor or fragrance. Source Naturals was created in 1982 by CEO Ira Goldberg to support each individual's potential to enjoy optimal health. The product is manufactured in the USA, in Scotts Valley, CA, under the Good Manufacturing Practices (cGMPs) established by the US Food and Drug Administration (FDA).
