Thorne Research L-Tryptophan, 500mg

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.

Supplementing with L-tryptophan allows the body to use it where it is needed most - for protein synthesis, niacin formation, or as a serotonin/melatonin precursor.* For optimal L-tryptophan absorption and transport across the blood-brain barrier, it is recommended to take L-tryptophan with a dietary carbohydrate.
