Tryptophan amino acid, buy l-tryptophan

L-tryptophan is an essential amino acid that is not synthesized in the body and comes from the diet. L-Tryptophan plays a critical role in the production of serotonin and melatonin, which support good mood, healthy sleep and immune function. L-trypotophan also supports the functioning of the immune system, as the body forms kynurenic acid from it, which regulates the immune system. When needed, the body converts L-Trypotophan to niacin, which supports circulation, nervous system health, metabolism, and the production of hydrochloric acid for the digestive system.
