Zen Theanine® contains L-theanine, a calming amino acid which is beneficial for those who suffer from stress and anxiety, or those who find it difficult to focus, relax, or fall asleep. L-theanine is a unique amino acid found almost exclusively in green tea. It helps reduce nervousness and restlessness, promoting relaxation but without causing drowsiness. L-theanine takes effect within 30-40 minutes and alters brain wave activity, calming racing thoughts and creating feelings of “zen” while promoting alertness and concentration. It influences the levels of the neurotransmitters dopamine, serotonin and GABA in the brain, balancing mood, sleep and even learning capacity. L-theanine reduces feeling of stress by inhibiting some of the actions of norepinephrine (a stress hormone) in the central nervous system.
