Diet Pepsi is a diet cola produced by PepsiCo. It is a sugar-free, low-calorie alternative to regular Pepsi, with a lighter, crisper taste. It is made with artificial sweeteners like sucralose and acesulfame potassium, Carbonated water, Caramel Color, Phosphoric acid, Artificial and natural flavors, Caffeine, Sodium benzoate, and Sodium citrate among other ingredients.
It is available in cans, bottles, and vending machines and has been marketed with slogans such as “You’ve got the right one, baby” and “Light, crisp, refreshing.” Diet Pepsi also has a caffeine-free version. It competes with other diet colas such as Coca-Cola’s Diet Coke and Dr. Pepper’s Diet Dr. Pepper in the marketplace.
Diet Pepsi contains about 35 milligrams of caffeine per 12-ounce (355-milliliter) serving, which is similar to the amount of caffeine found in other cola beverages. The caffeine content may vary slightly depending on the country and specific production run.
For comparison, a 12-ounce serving of Coca-Cola Classic contains about 34 milligrams of caffeine, while a 12-ounce serving of Mountain Dew contains about 54 milligrams of caffeine. It’s worth noting that some people are more sensitive to caffeine than others, so the effects of caffeine can vary from person to person. If you’re sensitive to caffeine, it’s best to consume it in moderation or avoid it altogether.
