Human: nutritional supplement, antioxidant. Tryptophane is the precursor of 5-hydroxytryptamine which is an important neurotransmitter of human body; it is also one of human essential amino acids; it is applied in nutrition supplements for pregnant woman and infant specific milk power; it is used as a curative of aniacinosis (pellagra); it's used as a tranquilizer to adjust energetic rhythm and improve sleeping.
Animal: it's used to improve animal food ingestion, weaken stress reaction, improve animal sleeping, increase antibody of fetus and young animal and improve milk secretion of milk yielding animals; it's also can be used to reduce high quality protein dosage in daily ration, reduce feed cost, protein feed consumption of daily ration and save formula space.
