L-Tryptophan Dietary Supplement for Relaxation 1000 MG Now Foods

Tryptophan is an essential amino acid; therefore, it is not synthesized by the body and must be obtained through diet. Tryptophan plays a critical role in the production of serotonin and melatonin, which help maintain a positive mood, healthy sleep, and proper immune system function. Each batch of NOW® L-tryptophan is tested for the absence of peak E and microbial contamination.

NOW® L-Tryptophan Double Strength contains twice as much L-tryptophan (1000 mg per tablet) as our regular product (500 mg per capsule).
