Product Description

Unlock relaxation, restful sleep, and a positive mood with the powerhouse amino acid L-tryptophan. This essential compound plays a crucial role in the production of melatonin and serotonin, the hormones that govern our mood, stress response, and sleep patterns. Boost your immune system as well, as L-tryptophan acts as a precursor to the kynurenines that regulate immunity. Plus, it converts to niacin in the body, promoting circulation, a healthy nervous system, efficient digestion, and the production of hydrochloric acid. Discover the purity and quality you can trust with Source Naturals L-Tryptophan – regularly tested to ensure the highest standards.
