L-Theanine — Supplement Grade
Allzone Trading supplies L-Theanine as a white crystalline powder to manufacturers and formulators in Canada and international B2B markets. Also referenced as Theanine, gamma-glutamylethylamide. L-Theanine is a non-protein amino acid found naturally in tea leaves and produced commercially by fermentation or chemical synthesis. It is highly water-soluble, stable across normal beverage processing temperatures and carries a mild umami note that formulators account for in flavour design.

Technical & procurement detail
What L-Theanine is and what it does+
L-Theanine is a non-protein amino acid found naturally in tea leaves and produced commercially by fermentation or chemical synthesis. It is highly water-soluble, stable across normal beverage processing temperatures and carries a mild umami note that formulators account for in flavour design.
Fermentation-derived and synthetic material behave differently on the label+
Both routes deliver the same molecule, but only fermentation-derived material supports a naturally-sourced declaration, and optical purity claims differ between routes. State whether your label position requires a fermentation route so the matching supplier grade and its documentation are requested.
Documentation and specification+
Assay, particle size, solvent residue, microbiological limits and heavy-metal limits differ between producers and grades. Allzone confirms the applicable specification with the supplier before quoting and shares the technical data sheet, safety data sheet and certificate of analysis for the exact material offered, so the values you evaluate are the values you receive.
