Description

Read more about this product

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 customers 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. It is a non-toxic, highly desirable mood modulator.

Beware of Imitations: The L-theanine used in this product is Suntheanine, the only pure form of L-theanine protected by 40 U.S. and international patents and scientifically proven in clinical studies to be safe and efficacious. Independent laboratory analysis has verified that certain other products on the market claiming to contain “L-theanine” are only half L-theanine, the other half being a different form of theanine known as “D-theanine” which has not been scientifically evaluated in published studies.
