MiO is a water flavor enhancer. It comes in Berry Pomegranate, Strawberry Watermelon, Fruit Punch, Mango Peach, Sweet Tea and Peach Tea. There are 24 servings in each little bottle with zero calories. They are naturally flavored. Add as little or as much as you like. I'll never buy Vitamin Water or Sobe again. Peach Tea and Mango Peach are my favorites, but I gather that most people like Strawberry Watermelon because that's the one that's always off the shelf!
