L – tryptophane

L-Tryptophan is an essential amino acid known for its crucial role in protein synthesis, neurotransmitter production, and mood regulation. It serves as a precursor to serotonin, melatonin, and niacin, which support mental well-being, restful sleep, and healthy nervous system function. Since the body cannot produce L-Tryptophan naturally, it must be obtained through diet or supplementation.
