7UP started life in 1929 containing an actual mood-stabilising drug in the recipe, and depending which country you buy it in today, you're technically buying a product from one of two entirely separate companies.
The lithium years
7UP launched in St Louis in 1929 under the name "Bib-Label Lithiated Lemon-Lime Soda", and the lithiated part wasn't just branding — it contained lithium citrate, a compound now used medically as a mood stabiliser. The drink was renamed 7UP in 1936, and the lithium citrate stayed in the formula until 1948, when it was removed following tightening restrictions on lithium in food and drink.
Built on being caffeine-free
7UP has been caffeine-free since the original formula, and its marketing has directly leaned on that point for decades as a point of difference from cola, most memorably with a campaign built around the line that it never had caffeine and never would.
Two companies, one name
Since 1986, 7UP has effectively been two separate businesses under one trademark: Keurig Dr Pepper owns and sells 7UP in the US, while PepsiCo holds the rights to the brand everywhere else in the world, including the UK, where it's produced under licence. It's a genuine oddity in soft drinks — the same name, the same logo, but two unrelated companies depending which side of the Atlantic you're standing on.
Why UK 7UP doesn't taste identical to US 7UP
Formulation differs slightly between the two. The UK version is sweetened with sugar, while the US version uses high-fructose corn syrup, which gives the two a noticeably different sweetness and mouthfeel side by side, the same kind of gap that shows up between UK and US versions of several other soft drinks.
Frequently asked questions
Did 7UP really contain lithium?
Yes. It launched in 1929 as 'Bib-Label Lithiated Lemon-Lime Soda' and contained lithium citrate, a mood-stabilising compound. It was renamed 7UP in 1936, and the lithium citrate was removed from the formula in 1948.
Is 7UP caffeine-free?
Yes, 7UP has always been caffeine-free, and its advertising has leaned on that point directly for decades, contrasting it with caffeinated colas.
Is UK 7UP the same as US 7UP?
Not quite. The two versions are owned by different companies (Keurig Dr Pepper in the US, PepsiCo internationally) and the UK version is sweetened with sugar rather than the high-fructose corn syrup used in the US formula, giving it a slightly different taste.
