SuperBeets Heart Chews combines clinically-researched grape seed extract plus non-GMO beetroot to support blood pressure health, blood flow, and energy the way nature intended - without caffeine or stimulants.* Each serving provides 150mg of clinically-researched grape seed extract derived exclusively from the renowned French Loire Valley region. In a 16-week placebo-controlled study of healthy men & women, the grape seed extract in SuperBeets Chews was clinically shown to be nearly 2 times as effective at promoting normal blood pressure already in the normal range as a healthy lifestyle alone. SuperBeets Chews are naturally flavored and contain no artificial sweeteners or colors.
