That's the thing; potatoes were given daily or even several times daily when they were available, which got really common. Limes/lime juice were rationed more carefully. I can't find the reference now, but there was even a British expedition to the Antarctic relying on limes that got stricken with scurvy, and it could not be explained why at the time.

Fermented cabbage products like sauerkraut were trialed and were successful, but weren't widely adopted, perhaps because of the Brits' tendency to cook it in iron cookware that gave it an unpleasant metallic taste.

Still funner fact: Albert Szent-Györgyi was awarded the Nobel Prize in 1937 for (among other things) discovering Vtiamin C in paprika. This was basically the point at which it finally started to become understood.

Funner fact: the British were dismayed to find out that limes don't actually prevent scurvy; although they taste sour because of citirc acid, they don't actually contain a lot of Vitamin C. It turns out there was some confusion about the translations for words like limón that might might mean limes, lemons or even both. What we know as limes were just easier to come by in a lot of British colonies, so that's what they used, with inconsistent and sometimes disappointing results.

Even funner still fact: scurvy was widespread in winter months in Europe before potatoes were cultivated from the New World in the 17th Century. Potatoes gained popularity because they grew easily on land that might otherwise be unusable for farming, and potatoes could be stored for months with little effort. Through an accident that wasn't understood until the 20th Century, it turned out that potatoes contained just enough Vitamin C to help stave off the worst of scurvy. At about the same time limes were adopted, potatoes became more common for provisioning ships too, and the reduction in scurvy was misattributed to limes.

Edit: forgot supporting link about Vitamin C in potatoes, sry
