Theanine CAS:3081-61-6 Manufacturer Supplier

L-Theanine is the major amino acid found in Camellia sinensis, the source of green tea. It is an analog of the excitatory neurotransmitter, glutamate, and thusly, binds to glutamate receptors. L-Theanine can antagonize various glutamate receptor subtypes as well as inhibit glutamine and glutamate transporters, which has been shown to be neuroprotective in animal models of focal cerebral ischemia. Further, L-theanine is reported to increase brain levels of dopamine, serotonin, GABA, nerve growth factor, and brain-derived neurotrophic factor.

Application and Effect

Theanine is a safe and non-toxic photogenic food supplement.It has been studied as a food additive and functional food in relation to human nutrition.It has noticeable bioactivities including anti-cerebral ischemia-reperfusion injury, stress-reducing, antitumor, anti-aging, and anti-anxiety activities.A non-protein amino acid mainly found naturally in the green tea plant. It may have activity in modulating the metabolism of cancer chemotherapeutics agents.In addition, theanine is reported to promote the release of the inhibitory neurotransmitter γ-aminobutyric acid [GABA], which in turn regulates dopamine and serotonin levels in the brain. Thus, theanine consumption has been closely associated with relaxation and improved learning ability.
