Yeah. I think it's probably safest to supplement, especially if you don't eat any fortified foods like supermarket bread or cereal, the godlike Ben Goldacre notwithstanding. I never have, and I thought having a bit of marmite would be fine, but I've recently been diagnosed with severe B12 deficiency and have to go for massive injections every other day, which aren't very pleasant. B12's not something you want to be deficient in.
