Quantum Energy Squares deliver Organic caffeine (other bar brands don't) while also providing the protein and additional macronutrients that Energy Drinks can't! By combining the "energy from Energy Drinks" with the "nutrition from Nutrition Bars" our unique and innovative offering expands the reach of traditional energy bars well beyond the bar set. Rise to any occasion with natural caffeine. No jitters, no crash, just smooth steady energy in a tasty square of fruits, nuts & seeds. How does it work? When caffeine is combined with real whole foods, it's more evenly absorbed by the body, creating smooth steady energy.
