For that Buddha-like feeling! 200 mg of Zen offers a unique and natural path to relaxation without sedation.* This formula contains a combination of L-theanine and GABA. L-theanine is found in green tea (Camellia sinensis) and has been shown to support the production of alpha-wave activity in the brain.
L-theanine is one of the few supplements that readily cross the blood-brain barrier. In doing so, it exerts subtle changes in the brain's biochemistry. One of the changes researchers discovered is that L-theanine significantly increased dopamine concentrations in the brain.(1) Dopamine is a neurotransmitter said to affect human emotions.
GABA primarily functions in the body as a powerful inhibitor of neurotransmitters and to help maintain relaxed levels of neuron activity. Over-stimulated or over-active neurons may lead to feelings of restlessness, irritability, and sleeplessness. GABA inhibits nerve cells from over-firing, to promote feelings of calmness, stability and well-being.
