What is 7up flavor?

7up is a lemon-lime flavored soda that was first introduced in the United States in 1929. It contains carbonated water, high fructose corn syrup, citric acid, natural and artificial flavors, potassium benzoate, and is caffeine-free. The original formula of 7up contained lithiated lemon soda, which was marketed as a cure for hangovers and other ailments. However, this ingredient was removed in the 1950s due to concerns about the safety of lithium. Over the years, 7up has introduced several different flavors, including Cherry 7up, Diet 7up, 7up Plus, and several limited-time offerings. Today, 7up remains one of the most popular carbonated soft drinks in the world.
