GU Chomps offer a fresh change of pace from gels and an answer to that moment in your run, ride, ski, swim, hike when you just gotta have something to chomp on. Chomps contain a balance of complex and simple carbs for fast and usable energy. They also offer amino acids, which provide extra energy during exercise as well as the antioxidants vitamins C and E that combat tissue breakdown. And to help you stay hydrated and firing on all cylinders, they also have meaningful levels of electrolytes (sodium and potassium). Plus, two of the flavors include caffeine, which stimulates the central nervous system, increases the release of adrenaline and helps the body metabolize fat as fuel.
