The combination of fast and medium-burning carbohydrates in Clif’s Energy Gels provides you with a steady stream of usable fuel during workouts and races. Electrolytes help balance your fluid levels, while caffeine in three of the flavors gives a boost to your central nervous system and releases free fatty acids into your bloodstream, which can help spare your body’s limited glycogen stores. Clif uses 90% organic ingredients and a thin consistency that goes down easy in both hot and cold weather. Even the packaging has a special touch—the opening is narrow and has a litter-resistant leash, the corners are rounded for jersey pocket comfort, and each packet has a reduced carbon footprint.
