L Tryptophan

L TRYPTOPHAN
L-tryptophan is naturally found in animal and plant proteins. L-tryptophan is considered an essential amino acid because our bodies cant make it. It is important for the development and functioning of many organs in the body. After absorbing L-tryptophan from food, our bodies convert it to 5-HTP (5-hyrdoxytryptophan), and then to serotonin. Serotonin is a hormone that transmits signals between nerve cells. It also causes blood vessels to narrow. Changes in the level of serotonin in the brain can alter mood. - WebMD
