What is 5-HTP?

5-HTP (5-hydroxy L-tryptophan) is a precursor for the brain neurotransmitter serotonin, known as the feel-good brain chemical. Serotonin in turn is a precursor for the sleep neurotransmitter and hormone melatonin. Low levels of these neurotransmitters can result in mood, sleep, appetite and hormonal imbalances that can leave you feeling quite blue. Supporting a healthy balance of these neurotransmitters by supplementing with 5-HTP as a nutritional precursor helps support restful sleep, positive mood and a better regulated appetite.

Why use 5-HTP over L-Tryptophan?

L-Tryptophan is an essential amino acid found in protein foods that the body uses as a precursor to produce serotonin. However, this process only occurs naturally following enzymatic conversion with tryptophan hydroxylase which converts dietary tryptophan to 5-HTP. However, tryptophan can also be shunted down other biochemical pathways in the body. 5-HTP, in contrast, is already is a form able to easily cross the blood-brain-barrier for the production of serotonin in the central nervous system. In addition, unlike tryptophan which is in competition with other amino acids for absorption, 5-HTP is able to be absorbed easily and directly, with or without the presence of other amino acids.
