L-Tryptophan (Starmark Labs)
L-Tryptophan is an amino acid and essential in human nutrition. This means that it cannot be synthesized by the organism and therefor must be part of its diet. Amino Acids function as building blocks in protein biosynthesis. L-Tryptophan is also known as a direct precursor for serotonin (a neurotransmitter), and melatonin (a neurohormone).
