L-Theanine is a unique amino acid and natural phytochemical with psychoactive properties that is found almost exclusively in the green tea plant (Camellia sinensis) and is a close relative of glutamate. It crosses the blood brain barrier, increases dopamine and GABA (Gamma-Aminobutyric Acid) levels in the brain, and inhibits the stimulatory properties of caffeine. Studies have shown that taking L-Theanine exerts beneficial effects on brain metabolism and results in the emission of brain waves associated with a state of relaxation without causing drowsiness, as measured by increased generation of alpha-waves. It helps promote a restful, relaxed state while maintaining daytime alertness and is also scientifically shown to support healthy blood pressure levels that are already within normal range. It helps support the body's ability to deal with PMS and may improve learning ability and sensations of pleasure by affecting dopamine and serotonin neurotransmitters in the brain. Also, L-Theanine exerts protective effects on the brain by antagonizing glutamate toxicity and may help the body's immune response to infection by boosting the disease-fighting capacity of gamma delta T cells. A combination of L-Theanine with Caffeine (200mg each) is noted to be synergistic in promoting cognition and attention and has been shown to promote faster simple reaction time, faster numeric working memory reaction time, and improved sentence verification accuracy. The two have also been shown to reduce mental and physical stress and improve cognition and mood.
