Coca-Cola Zero or Coke Zero is a product of the Coca-Cola Company. It is a sugar-free variation of Coca-Cola. In the United States, where the drink was first introduced, Coke Zero is marketed as having zero calories (hence the Zero in the product's name), but in other countries it is marketed as having zero sugar. Coca-Cola Zero in fact has a negligible caloric value. Depending on the country in which it is made, it has about 0.8 to 2.1 KJ (0.2 to 0.5 Kcal) per 100 mL (3.4 US fl. oz.).
