L-Theanine Used to Reduce Anxiety

Doctors in this study measured anxiety levels in 18 university students who then took 200 mg of L-theanine or a placebo. While there was no change for placebo or for students with minimal anxiety, highly anxious students who took L-theanine had slower heart rate, better visual attention, and faster reaction times. Researchers said that, unlike conventional anti-anxiety treatments, L-theanine did not increase drowsiness, slow reflexes, or impair concentration. L-theanine also increased alpha brainwave activity, the type that emerges when eyes close and the body and mind relax.
