    Glossary Tryptophan

    essential amino acid involved in serotonin and melatonin production

    Tryptophan, also known as L-Tryptophan, is an essential amino acid that the body cannot produce on its own and must obtain from dietary sources like turkey, eggs, and dairy. It plays a crucial role in the production of serotonin, a neurotransmitter that regulates mood, and melatonin, a hormone that controls sleep-wake cycles.
