Highly-Trusted & Well-Researched L-Theanine

Made with quality in mind—our L-Theanine softgels are formulated with the patented ingredient, Suntheanine®. A clinically researched brand of L-Theanine, Suntheanine® has been shown to promote an alert state of relaxation and focus without causing drowsiness by supporting an increase in alpha brain waves and decreasing beta brain waves for an amplified mental state. Additional research suggests that Suntheanine® may help in improving sleep quality, heightening mental acuity & reducing negative side effects of caffeine.*
