Canada

I had imagined that it had to be a specific B vitamin that Health Canada was worried about for an actual reason, but no. Apparently you're just not allowed to add vitamins or minerals to foods in Canada unless they're on a very specific list of exceptions for particular foodstuffs. For instance if you sell dehydrated potatoes the only thing you're allowed to add is vitamin C.

So the question becomes WTF does Canada have against adding vitamins to things in general? How did that regulation come to be? Do other countries do it that way as well? Does Australia specify exactly which vitamins are allowed to be in vegemite when it's sold there? Is there a reason why the Canadians wouldn't simply add vegemite to the list when it's pointed out that they haven't got a category there that covers it? Eh well, whatever.
