L-Tryptophan (free-form), USP-Grade

Description

What this is

L-tryptophan is an essential amino acid and a foundational substrate in human metabolism, required for protein synthesis, neurotransmitter balance, and de novo NAD⁺ production under conditions of metabolic demand.

This product provides L-tryptophan in its unmodified, free-form crystalline state, at 100+% purity, meeting the most stringent USP pharmacopeial standards for quality, identity, and contaminant control acceptable for human pharmaceutical use.

The material is sourced and handled with an emphasis on chemical purity, batch traceability, and molecular identity, consistent with laboratory and clinical research standards. The pictured Certificate of Analysis (COA) reflect a commitment to known inputs—not blended, hydrolyzed, or reformulated consumer substitutes.

What this is NOT

This is not a peptide blend, protein hydrolysate, or proprietary amino acid complex. It is pure L-tryptophan, supplied as a powder to allow precise, titratable dosing.

We also offer pure, individual components, Niacin and Folate, both USP-grade as well, and most conveniently, the three precisely compounded by us exactly as should be for InfinaLife
