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. SERENE SCIENCE® L-TRYPTOPHAN is extremely pure 
and is regularly tested to ensure the highest standards of quality.
