Life Extension Theanine is the predominant amino acid of tea that produces calming effects in the brain by increasing levels of serotonin and dopamine, and blocking the binding of L-glutamic acid to glutamate receptors. Life Extension members can enjoy the benefits of this unique ingredient in a 100 mg supplement. This feel good supplement causes no adverse reactions. In fact, in Japan, theanine is added to soft drinks and chewing gum for the purpose of inducing relaxation.
The calming, mood-enhancing effect is achieved by helping to increase alpha-brain waves, electrical brain activity commonly present when you are very relaxed, literally putting you in a better mood.
Just as meditation, massage or aromatherapy quiets the mind and body, theanine plays a role in inducing the same calm and feeling of well-being without drowsiness. It is a non-toxic, highly desirable mood modulator.
