Life Extension L-Tryptophan 500 mg — 90 Vegetarian Capsules

L-tryptophan is an essential amino acid and the dietary precursor to serotonin and melatonin — the key neurotransmitters regulating mood, emotional well-being, and healthy relaxation. Unlike 5-HTP (which is one step closer to serotonin), L-tryptophan follows the body's natural serotonin synthesis pathway, providing a more physiological approach to serotonin and melatonin support.

Each bottle contains 90 vegetarian capsules for a 3-month supply at standard dosing.
