Amino acid analog of glutamine, uniquely found in green tea. Increases brain serotonin, dopamine and GABA levels and binds to AMPA, kainate and NMDA receptors. Has been shown to exert neuroprotective effects in animal models possibly through its antagonistic effects on group 1 metabotrophic glutamate receptors. Behavioural studies with rats suggest L-Theanine to positiveley affect learning and memory processes. Promotes self-renewal of human embryonic stem cells.
