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.*
