SOURCE NATURALS L-TRYPTOPHAN 500MG 90 CAPS

L-Tryptophan Mood, Relaxation, Sleep 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.* 500 mg Capsule Option Available: 30, 60, 90, 120 Suggested Use: 1 capsule three times daily, between meals and preferably with fruit juice. To support restful sleep, take an additional 3 capsules before bed. Allergies: Contains no yeast, dairy, egg, gluten, soy or wheat. Contains no preservatives, or artificial color, flavor or fragrance.
