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.
