Tryptophan, also known as β-indolylalanine, is one of the essential amino acids of the human body. Tryptophan is an important precursor substance for auxin biosynthesis in plants. Its structure is similar to IAA, and it is ubiquitous in higher plants.
L-Tryptophan is a very effective agent for positive mood and relaxation. It is widely used in dietary supplement production as it improves neurotransmitter balance and optimizes brain function. The compound is also claimed to help prevent and treat various mood-associated health conditions.
L-Tryptophan is the L-enantiomer of the naturally occurring compound Tryptophan. It is an essential amino acid that serves a vital role in the human body as a precursor to the production of the neurotransmitter serotonin. As an essential amino acid, L-Tryptophan is not produced in the body and must be supplemented through food and other dietary sources.

Human Nutrition: Nutritional supplement and antioxidant. Tryptophan is an important neurotransmitter (5-hydroxy tryptamine precursor). It is an essential amino acid used in pregnant women's supplements, preschool milk powder, and treatments for nicotinic acid deficiency (pellagra). It acts as a sedative to regulate spirit rhythm and improve sleep.
Animal Nutrition: Promotes feed efficiency, weakens stress reactions, and improves sleep. It increases antibodies in fetuses and cubs and improves dairy cattle lactation. It helps reduce high-quality protein dosage in rations, saving feed costs and formula space.
