100% pure tryptophan powder, an essential amino acid used by the body to produce serotonin and melatonin.
Tryptophan is an essential amino acid, meaning it can’t be produced by your body, and must be obtained through your diet or nutritional supplements. Our Tryptophan comes in powdered form and is great for mixing in with your favourite shake formula to up your intake of tryptophan.
Tryptophan is best known as a precursor for the production of serotonin and melatonin in the body.
