Introduction of L-tryptophan:

L-tryptophan is an amino acid essential to human metabolism because it is the metabolic precursor of serotonin (a neurotransmitter), melatonin (a neurohormone), and niacin (vitamin B3).* Other neurotransmitters and central nervous system chemicals, including dopamine, norepinephrine, and beta-endorphin, have been shown to increase following oral administration of tryptophan. Because of its effects on serotonin and melatonin production in the brain, L-tryptophan supplementation can benefit mood and can also promote relaxation, a benefit for individuals attempting to get to sleep.
