Theanine is a unique amino acid found almost exclusively in green tea that exerts beneficial effects on brain metabolism.* Theanine induces relaxation without causing drowsiness, as measured by increased generation of alpha-waves.* Theanine may improve learning ability and sensations of pleasure by affecting dopamine and serotonin neurotransmitters in the brain.* Also, theanine exerts protective effects on the brain by mitigating glutamate toxicity.*
