FAST FUEL FOR RUNNERS, HIKERS, BIKERS, & OTHER ENDURANCE ATHLETES: These chews are the perfect source of energy to power you through to the finish line. Each flavor offers different levels of caffeine & sodium for energy & electrolyte replenishment. PERFORMANCE-ENHANCING CAFFEINE TO AVOID THE BONK: Caffeine is an effective ingredient known to give boosts of energy. Only 3 flavors contain added caffeine: Black Cherry, Orange, & Tropical Punch. CLIF uses green tea extract as the caffeine source. CARBOHYDRATES FOR ON-THE-GO ENERGY: Consuming carbs during activity enhances performance by proving working muscles with a continuous supply of energy. If carbs are consumed during activity, the body can sustain activity for a longer period of time. ELECTROLYTES FOR HYDRATION & REPLENISHMENT: During activity, BLOKS provide concentrated & easy-to-chew energy along with nutrients such as sodium & potassium for electrolyte replacement. Ideal performance requires an adequate supply of electrolytes. ORGANIC INGREDIENTS TO FUEL YOUR BODY NATURALLY: CLIF started their journey to use organic ingredients more than 12 years ago. They are committed to having 80% of all their ingredients be organic & sustainably sourced by the end of 2020.
