L-Theanine (Standard)

L-Theanine (Standard) is the analytical standard of L-Theanine. This product is intended for research and analytical applications. L-Theanine (L-Glutamic Acid γ-ethyl amide) is a non-protein amino acid contained in green tea leaves, which blocks the binding of L-glutamic acid to glutamate receptors in the brain, and with neuroprotective, anticancer and anti-oxidative activities. L-Theanine can pass through the blood–brain barrier and is orally active[1][2][3].
