While a can of 7UP has the same amount of calories as a can of Sprite and boasts the same all-natural, lemon-lime flavor, they're quite distinct from each other in a number of ways, starting with their histories. Let’s find out the ways the two soft drinks differ from one another.

7UP was created back in 1929 by Charles Leiper Grigg, and the soda was marketed as Bib-Label Lithiated Lemon-Lime Soda. The original formula included the mood-stabilizing drug lithium citrate in its formula. Some even believe the "7" in 7UP refers to the atomic mass of lithium, although it could be in reference to the drink's original seven ingredients.

Sprite, however, never included a mood stabilizing drug in its formula, and wasn't even invented until 1959. It also had a much longer and clunkier name to begin with: Clear Lemon Fanta, and was introduced to the U.S. market to compete directly with 7UP, just two years after its formulation in West Germany.

While Sprite is owned by the Coca-Cola company, 7UP is owned by Keurig Dr Pepper in the United States, and PepsiCo in the rest of the world. Additionally, Sprite uses sodium citrate in its formula, while 7UP uses potassium citrate.
