Source Naturals brings you this pure essential amino acid that supports relaxation, restful sleep and a positive outlook. Helps in the synthesis of both melatonin and serotonin. A precursor to the kynurenines that regulate immunity, L-tryptophan also converts to niacin when the body needs it in order to support circulation, the nervous system and the metabolism of food.
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.*
