Theanine is designed to support calmness and relaxation without drowsiness. Theanine is extracted from green tea leaves. L-theanine is a unique free form amino acid found only in the tea plant and in the mushrooms Xerocomus badius and certain species of genus Camellia, C. japonica and C. sasanqua.

L-theanine is a relaxant that increases alpha waves producing mental and physical relaxation decreasing stress and anxiety, without inducing drowsiness. Stress and anxiety are debilitating conditions that can shorten your life span while lessening performance, well-being, and the enjoyment of life. Stress can impair the ability to perform mentally. It may result in reactions to situations that cause enhanced frustration, hostility or even injury. Stress slowly destroys the immune system, lowering resistance to disease and thus allowing degenerative and opportunistic diseases to occur.
