L-Tryptophan

Click To View Products

L-Tryptophan is an essential amino acid which is not synthesized by the body and must be obtained in the diet. It is a precursor from which our brains make serotonin, which is then used to calm you down and make you sleepy.

Tryptophan also helps in niacin (B vitamin) production.
