Search Results for "Tryptophan"

L‑tryptophan is the essential amino acid your brain uses to make serotonin and, downstream, melatonin. Think of it as upstream “fuel” for calm, mood, and sleep—when diet is low or needs are high, extra tryptophan can tilt brain chemistry toward rest and steadier emotions. Researchers also study it for premenstrual mood symptoms and appetite control via gut–brain hormones.
