Product Description

    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. Therefore, L-Tryptophan is classified as a nutraceutical, a micronutrient, and an anti-depressant agent.
