Stress Solution contains patented Suntheanine (L-theanine), which helps promote a relaxed, calm feeling without causing drowsiness. A human study has shown that 200 mg of Suntheanine helps increase alpha wave activity in the brain, resulting in an alert state of relaxation without causing sleepiness. Stress Solution also contains CalmaBlend, a mix of Passion Flower, Lemon Balm and Asian Ginseng, to help ease occasional nervous tension and promote a relaxed, calm feeling.
