According to the Center for Science in the Public Interest, both regular Coca-Cola and Coca-Cola Zero Sugar contain approximately 34mg of caffeine per 12-ounce can. This fact is surprising to many, who assume the sugar-free version would have a different caffeine profile than the original.

A standard 12-ounce can of Diet Coke contains approximately 46 milligrams of caffeine, roughly 30% more than the 34 milligrams found in a regular Coke. This might come as a surprise, but this difference is a deliberate formulation choice made by The Coca-Cola Company to perfect the flavor profile and is the primary reason why does Diet Coke have more caffeine than regular Coke.
