  • Suntheanine

    Suntheanine is Taiyo’s pure form of L-theanine, produced via a patented fermentation process that mimics the natural process in green tea leaves. It promotes relaxation without causing drowsiness, positive mood, mental clarity, focus, reduces nervous tension, and helps prevent the negative side-effects of caffeine.
