Phosphoric acid: Enhances flavor and acts as a preservative. Aspartame: Artificial sweetener that provides sweetness without calories.

Acesulfame potassium (Ace-K): Another artificial sweetener used in combination with aspartame. Potassium citrate: Regulates acidity and adds flavor.

Natural flavors: Blend of ingredients to mimic the taste of regular Coca-Cola.
