L-theanine is an amino acid found in green tea that exerts a profoundly relaxing, yet non-drowsy effect.
It helps with stress, improves learning and concentration and may even reduce the jitters brought on by too much caffeine in coffee or cola.
This is the Ëfeel-good' amino acid found in green tea. Studies show that L-Theanine produces tranquilizing effects in the brain without drowsiness. It calms by helping to increase alpha-brain waves, the electrical brain activity commonly present when you are very relaxed.
By diminishing the feeling of stress, worry and anxiety, L-Theanine may actually help with focus, learning and concentration.
Single dosages of 200 mg of L-Theanine have been shown effective in studies.
