What's L-Theanine?

L-Theanine is a characteristic amino acid in tea, synthesized by glutamic acid and ethylamine in the roots of tea tree under the action of Theanine synthase, which is an important substance to form the taste of tea, mainly expressed as fresh and sweet, and is the main component of tea to produce sweetness.

Naturally occurring Theanine are L-type, pure product is white needle crystal, melting point 217℃～218℃, specific rotation degree [α]D20=0.7°, extremely soluble in water, insoluble in organic solvents such as ethanol and ether, aqueous solution is slightly acidic, caramel aroma and MSG-like fresh taste, taste threshold is 0.06%.

As the characteristic non-protein amino acid with the highest content in tea, Theanine is safe and non-toxic, and has a variety of biological activities such as antioxidant, immune modulation, delaying aging, and antagonizing cell excitotoxicity due to glutamate overload. Meanwhile, 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, reducing the chance of colds and flu in the body.

Function Of L-Theanine

L-Theanine crosses the blood-brain barrier and affects brain activity by promoting increased alpha, a pattern of brain activity associated with a more relaxed state. l-Theanine's tendency to increase alpha waves may explain its role in reducing stress and anxiety In animal studies, l-Theanine has been shown to affect neurotransmitter signals in the brain, but these effects have been less studied in humans.

It is used to help prevent and treat diseases including:Anxiety, depression and other mood-related disordersInsomnia and sleep problemsCognitive loss, dementia and Alzheimer's diseaseStrokeHigh blood pressure and other cardiovascular diseasesPost-traumatic stress disorder (PTSD)SchizophreniaShort attention span Drug dependence.L-Theanine may help improve the effectiveness of drugs used to treat cancer.

Both promote overall mental health and energy levels, but theanine works better as a natural stress reliever. Glutamine is one of the 20 naturally occurring amino acids in dietary protein and is the most abundant amino acid in the blood, accounting for 30 to 35 percent of the amino acid nitrogen in the blood.
