Beetroot from high-quality, non-GMO beets.

How to Use

Take one delicious grape cherry-flavored chew any time of day.

For added cardio-powered benefits, use SuperBeets® CardiO2 Energy Chews in combination with SuperBeets® Sport Powder. Take SuperBeets® Sport Powder 20 to 30 minutes before exercising. Then layer in SuperBeets® CardiO2 Energy Chews during your workout when you want to go the extra mile.

The Science

SuperBeets® CardiO2 Energy Chews work through dual mechanisms of action to deliver what your body needs to stay energized and resilient. Unlike conventional beet products that contain just 1% or less of betalains, our clinically developed extraction process yields a highly stable and soluble 25% standardized concentration, which is the highest concentration of betalains. This proprietary method isolates and preserves the most effective compounds to provide powerful 5-in-1 support.

Other Features and Attributes

SuperBeets® CardiO2 Energy Chews are vegan, gluten-free, soy-free, dairy-free, caffeine-free, non-GMO and made without artificial colors or sweeteners. They are third-party tested for purity, potency and safety.
