L-Theanine (Standard) is the analytical standard of L-Theanine, primarily used for research and analytical applications. L-Theanine (L-Glutamic Acid γ-ethyl amide) is a non-protein amino acid found in green tea leaves. It competitively blocks the binding of glutamate to glutamate receptors (such as NMDA, AMPA, and Kainate receptors) in the brain, exerting neuroprotective, anticancer, and antioxidant activities. L-Theanine can effectively cross the blood-brain barrier and exhibits high oral bioavailability.
