Born in yoga studios and long consumed by the health conscious, ZICO coconut water has been discovered by athletes worldwide. Tennis players including John Isner, Bethanie Mattek-Sands  and Magdalena Rybarikova drink the stuff.

According to the company Isner requested the beverage during his U.S. Open 5th set vs. Andy Roddick to help with cramping. He went on to win the match in a tie-breaker.

They call it nature's sports drink. If you've ever had coconut milk out of a fresh coconut, that's the taste, a bit watery with light coconut flavor, exactly what the natural ZICO tastes like.

Coconut milk is in fact packed with potassium, low in acidity and helps to rebuild blood volume.* One 11 oz. all-natural ZICO offers more potassium than a banana, zero fat, zero sugar and four essential electrolytes (plus the potassium). Drink it before, during and after your workout as a good-for-you sports drink alternative, just 60 calories.
