Wondering whether B vitamins are for a hangover? It's a common question and one that doesn't have a straightforward answer.

If you’re reading this article, the chances are that you’ve already tried many different supposed hangover cures in your time. Drinking water and taking painkillers help, but nothing quite does the trick.
