Description of L-Theanine Powder

L-Theanine, a natural component found in green tea, can also be synthesized by subjecting L-glutamic acid to high-pressure heating to form pyrrolidone carboxylic acid, then adding anhydrous monoisopropanolamine and subjecting it to high-pressure heating. L-Theanine, a unique free amino acid present in tea leaves, is the γ-ethylamide of glutamic acid and has a sweet taste. The content of L-theanine varies depending on the variety and part of the tea plant. It typically accounts for 1%-2% of the dry weight of tea leaves.
