So, what is Diet Mountain Dew? This soda is a variant of the popular Mountain Dew brand, which is owned by PepsiCo. Diet Mountain Dew differs from regular Mountain Dew in that it is sweetened with aspartame, an artificial sweetener, instead of high-fructose corn syrup. This change means that Diet Mountain Dew has fewer calories and less sugar than regular Mountain Dew.

However, both varieties of Mountain Dew contain caffeine. Diet Mountain Dew’s caffeine content can vary slightly depending on where and how it is produced, but a typical 12-ounce can contains 54 milligrams of caffeine.
