Kellogg's™ Special K2O™ Protein Water
From Wikipedia, the free encyclopedia
On November 16, 2006 Kellogg Company introduced a new beverage called K2O available in Strawberry Kiwi, Lemon Twist and Tropical Blend flavors. Marketed as low-calorie alternative protein drink, a 16-ounce bottle of K2O contains 5 grams of protein and 50 calories.
As potassium oxide is highly corrosive to human tissue, it may be considered somewhat ironic for a health drink to bear this name K2O.
