L-Tryptophan is an essential amino acid - one that must be obtained from food or supplements, as humans cannot synthesize it. L-tryptophan is utilized for protein synthesis, and is metabolized in the body into the neurotransmitters serotonin and melatonin. A small percentage of L-tryptophan is converted into niacin. Clinical studies have shown supplementation with L-tryptophan improves mood and helps sleep.

Thorne's pure, pharmaceutical-grade L-tryptophan has undergone numerous quality control tests to ensure its purity and safety.
