Pure Energy 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, Pure Energy also features a caffeine pterostilbene cocrystal. Initial reports suggest this cocrystal'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 5 g of carbohydrates per serving and zero sugars, Pure Energy simply gives your body what it needs to produce energy.*
