Premium L-Theanine 99% Powder
Premium L-Theanine Powder is a high-purity amino acid naturally found in tea leaves (Camellia sinensis), making up 1–2% of their dry weight. It is water-soluble, has a clean, slightly sweet taste, and is an important contributor to the soothing flavor profile of tea. Traditionally enjoyed for centuries in tea, L-theanine has more recently gained popularity as a supplement for promoting relaxation, supporting focus, and encouraging a calm yet alert mental state.
Our L-theanine is produced through enzymatic fermentation for maximum purity. (Enzymatically fermented L-theanine is not currently approved for sale in the EU.)
