L-Theanine (PhytoSure™) – 60 capsules

L-Theanine with Phytosure™

L-Theanine is a natural amino acid primarily found in green tea. Unlike many other amino acids, it is not used as a building block for proteins but functions as a signaling amino acid in the body. It is not produced by the human body, making it a unique plant-based compound.

The Phytosure™ Standard

L-Theanine from Health Thru Nutrition is exclusively formulated with Phytosure™ L-Theanine. CAS Biosciences developed PhytoSure™ as a quality benchmark. The PhytoSure certification guarantees 100% assurance that the ingredient exceeds all requirements regarding plant species, plant part, standardization, claims, specifications, and traceability. PhytoSure™ also ensures that every active ingredient is free from carriers, fillers, additives, and contaminants.

Fun Facts About L-Theanine

Did you know that L-theanine is the flavor secret of tea? As a unique amino acid, it gives green, black, and white tea their distinctive umami flavor. The Camellia sinensis plant — the tea plant — exclusively contains high levels of L-theanine. Some mushrooms also contain it, but in much lower concentrations. Thanks to its compact molecular structure, specialized transport system (LAT-1), and unique chemical properties, L-theanine can cross into the brain quite easily.
