L-Theanine from Green Tea is a food-grade unique non-protein amino acid delivering calm-focus, stress-relief, sleep-support and attention-enhancement benefits via GABA, dopamine and alpha-brainwave modulation, used in nootropic and relaxation supplements.We supply bulk Green Tea L-Theanine sourced from leading China manufacturers, available in powder form for food and beverage manufacturers worldwide. Our Green Tea L-Theanine is widely used in focus supplements, calm formulas, relaxation products, attention supplements and energy drinks.
L-Theanine is produced by water extraction of Camellia sinensis leaves or by enzymatic/microbial synthesis.
This yields a white crystalline powder at ≥98% purity. It is the signature amino acid of green tea responsible for its calming effect without drowsiness, modulating GABA, serotonin, dopamine and increasing alpha brainwaves, widely used in focus, stress and sleep supplements (often paired with caffeine).
