Zenex Organic Green Tea Extract L-Theanine Powder Pack of 100 Gram

Green Tea Extract L-Theanine powder is the main amino acid found in camellia, the source of green tea. It is an analogue of excitatory neurotransmitter glutamate and therefore binds to glutamate receptors. Theonine (L-theanine) can antagonize various glutamate receptor subtypes and inhibit glutamine and glutamate transporters, which has been proven to have neuroprotective effects in animal models of focal cerebral ischemia. In addition, Theanine (L-theanine) can increase levels of dopamine, serotonin, GABA, nerve growth factor, and brain-derived neurotrophic factor in the brain.
