• Mood, Relaxation, Sleep

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.    

Suggested use
