What is Doctor’s Best L-Theanine with Suntheanine?
Doctor’s Best L-Theanine with Suntheanine is a patented form of the amino acid L-theanine. L-theanine is an amino acid found in green tea that is responsible for the relaxation-inducing effect of tea consumption. L-Theanine with Suntheanine has been shown to promote an alert state of relaxation. This is characterized by an increase in alpha brain waves (signifying a relaxed, alert state) and a decrease in beta brain waves (signifying an awake, excited state of mind). L-Theanine with Suntheanine may improve sleep quality, enhance mental acuity and soothe away tension and nervousness.

Why should I take Doctor’s Best L-Theanine with Suntheanine?
Doctor’s Best L-Theanine with Suntheanine contains 100% Suntheanine and is best known for its unique ability to promote relaxation without causing drowsiness. L-theanine is one of green tea’s natural health-promoting compounds. It is the ingredient that is responsible for both the taste and the relaxing effects of green tea. Research shows that supplemental L-theanine crosses the blood-brain barrier within 30 minutes of intake and thus is able to exert its effects directly on the brain.
