L-Tryptophan is an essential amino acid and the sole precursor to serotonin (via 5-HTP) and melatonin. It has the lowest plasma concentration of all amino acids, making it rate-limiting for serotonin synthesis. Competes with other large neutral amino acids (BCAAs) for BBB transport; carbohydrate intake enhances brain uptake.
