Understanding Diet Pepsi’s Composition
Unlike regular Pepsi, which is sweetened with high-fructose corn syrup or sugar, Diet Pepsi relies on artificial sweeteners to provide the familiar cola taste without adding calories. The 2025 version of Diet Pepsi has seen some tweaks in its formula due to changing health regulations and consumer demands for better alternatives.

6. Citric Acid

10. Sucralose (Possible Future Addition)
