 L- theanine(CAS No.:3081-61-6) is produced through fermentation. Fermentation production is an efficient and controllable biosynthetic method, mainly achieved through microbial engineering and enzyme catalytic technology.L-theanine is a unique non-protein amino acid found in tea，it can be used for sedative effects when added to food. 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. Also, it can soothe the nerves, enhance immunity, lower blood pressure, improve the brain, promote the brain's learning and memory functions, and effectively enhance the liver's detoxification function.
