Relaxation without drowsiness. Reduces stress and tension. Suntheanine® is the premier, patented form of the amino acid L-theanine.

Suntheanine® is the purest form of the L-theanine on the market today, containing 100% Suntheanine. L-theanine is an amino acid derived from green tea (produced in Japan) that is responsible for the relaxation-inducing effect of tea consumption.

L-theanine is synthesized in the roots of tea plants and transported to the leaves, comprising about 2% of the total dry weight of green tea leaves. It is the ingredient that is responsible for both the taste and the relaxing effects of green tea.

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). Suntheanine® may also improve sleep quality, enhance mental acuity and soothe away tension and nervousness.

Research shows that supplemental L-theanine crosses the blood-brain barrier within 30 minutes of intake and this is able to exert its effects directly on the brain.


Suntheanine® L-theanine is best known for its unique ability to promote relaxation without causing drowsiness.
