ATP Energy/ Electrolyte Drink transforms water into a great-tasting, revitalizing energy drink. Each stick provides a combination of B vitamins, electrolytes, trace minerals, amino acids, herbs, and antioxidants to fuel your body’s energy production. Building on these important nutrients, ATP Energy/ Electrolyte Drink also features PurenergyTM, a technology-driven, patent-protected ingredient that combines caffeine and pTeroPure® pterostilbene. Initial reports suggest that Purenergy’s caffeine may be absorbed more slowly and stay in your system longer than regular caffeine, which may help your energy last longer. With just 5g of carbohydrate per serving and zero sugars, ATP Energy/ Electrolyte Drink simply gives your body what it needs to produce energy.
