The soft drink 7UP does not contain caffeine. All other products in the 7UP line, including diet 7UP, 7UP Mixed Berry Antioxidant and 7UP Cherry Antioxidant also have caffeine-free formulas.
The main ingredients of the regular 7UP soft drink include filtered carbonated water, high-fructose corn syrup and citric acid. A substance called calcium disodium EDTA is also an important part of the formula, as it protects the flavor.
An 8-ounce serving of 7UP provides 102 calories, 25 grams of sugar and 30 milligrams of sodium and contains no protein or fat. In contrast, the diet version of this soft drink has zero calories. Diet versions are also manufactured for the berry- and cherry-flavored drinks.
