L-tryptophan is an essential amino acid; therefore, it is not synthesized by the body and must be obtained from the diet. L-tryptophan is critical for the production of serotonin and melatonin, which help support a positive mood, healthy sleep patterns, and proper immune system function. Each batch of NOW L-tryptophan is tested to be free of peak E and microbial contamination.
