Tryptophan is an essential amino acid; therefore, it is not synthesized by the body and must be obtained from the diet. 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 combination.

NOW Double Strength L-Tryptophan has twice the L-tryptophan (1000 mg per tablet) as in our regular strength product (500 mg per capsule).
