Function：Tryptophan is the precursor of the human body’s important neurotransmitter 5-hydroxytryptamine and one of the essential amino acids; used in nutritional supplements for pregnant women and special milk powder for infants; used in the treatment of niacin deficiency (pellagra) Medicine; as a tranquilizer, regulate mental rhythm and improve sleep. Other functions include
Promote the synthesis of hemoglobin
Prevention and treatment of mangy
Promote growth and increase appetite
