6 stress-relief supplements and herbs
L-theanine
Found in teas—high-quality green and black varieties—L-theanine increases the brain’s alpha-wave activity, leading to less anxiety and a feeling of calm. Higher alpha waves are also associated with greater mental sharpness. One study found that L-theanine reduced negative responses to stress. And in other research, it increased feelings of relaxation by 40 percent among people with serious behavioral disorders. Bonus: L-theanine doesn’t cause drowsiness.
Dose: 200 mg one to three times daily
