  • Encourages Positive Mood*
  • Promotes Restful Sleep*

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 contamination.

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