    L-Tryptophan is an essential amino acid (meaning that the body does not produce it, it must be derived from diet or through supplementation). It is needed in order to eventually produce serotonin and tryptophan. These messengers are able to transfer nerve impulses between cells. Without having many of these neurotransmitters being produced regularly, the brain would cease to deliver messages and thus cease to function.
