Product Details

The essential amino acid L-tryptophan is the precursor for the synthesis of both melatonin and serotonin, a hormone and a neurotransmitter involved with mood and stress response and sleep/wake cycles. It helps support relaxation, restful sleep, and positive mood. If needed, L-tryptophan converts to niacin in the body, an important B vitamin. Source Naturals L-Tryptophan is extremely pure and is regularly tested to ensure the highest standards of quality.
