Coca-Cola C2 (also referred to as Coke C2, C2 Cola, or simply C2) was a cola-flavored beverage introduced by The Coca-Cola Company first in Japan, then later on 7 June 2004 in the United States (and shortly thereafter, Canada), in response to the low-carbohydrate diet trend. This Coke product was marketed as having half the carbohydrates, sugars and calories compared to standard Coca-Cola.
