O2 Grapefruit Ginger – 12 Pack

To re-invent energy drinks for the better, the makers of O2 didn’t go back to the lab. They went back to basics. While some new-age energy drinks keep adding loads of artificial ingredients and sugar, O2 is simply infused with oxygen, electrolytes, and the same amount of caffeine you’d get in a cup of coffee. Add the refreshing natural flavors of grapefruit and ginger, and you have a sports drink that delivers all the recovery benefits an athlete needs with zero artificial ingredients and just 15 calories.
