Natural Factors L-Theanine is the ‘feel-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.
