Green Tea Extract L‑Theanine Powder | Natural L‑Theanine from Camellia Sinensis Leaf Bulk Supplier

We supply natural L‑Theanine powder extracted directly from green tea leaves (Camellia sinensis). A lot of buyers reach out specifically asking for tea-extracted material, rather than fermented L-theanine. We use water-based extraction, keeping the botanical origin intact.

We offer multiple HPLC assay grades. Every single batch comes with its own COA, HPLC chromatogram and full contaminant test reports. If you’re making nutraceuticals, functional food or beverage products globally, we can provide trial samples and support third-party lab testing as required.
