L-Tryptophan is an essential amino acid; therefore, it is not synthesized by the body and must be obtained from the diet or through supplementation. L-Tryptophan is critical for the production of serotonin and melatonin, which help to support a positive mood, healthy sleep patterns, and proper immune system function.

Every lot of NOW© L-Tryptophan is tested to be free of Peak E and microbial contamination.
