The essential amino acid L-tryptophan helps support relaxation, restful sleep, and feeling better. It plays part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response. 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.*
