L-Tryptophan is an essential amino acid a component of many plant and animal proteins. Essential amino acids are 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. L-tryptophan, in substantial quantities, is a natural sedative. Tryptophan also helps in niacin (B vitamins) production.
