    Theanine is a characteristic amino acid in tea. As the most abundant characteristic non-protein amino acid in tea, theanine is safe and non-toxic with no side effects. It has multiple biological activities such as antioxidation, immune regulation, anti-aging, and antagonizing the cellular excitotoxicity caused by excessive glutamic acid.  At the same time, L-theanine, as an alkylamine, can activate γ-T immune cells to promote cell proliferation and cytokine secretion, enhance the ability to resist tumor cells and reduce the infection of external microorganisms, thereby lowering the chances of the body catching colds and flu.
