An interesting anecdote about B12 is that it's actually coming from bacteria, usually found in the ground. Animals are rich in B12 because they eat grass. Technically if you don't wash your vegetables you would get more B12, but you would also increase your chances of catching a bad bug. B12 isn't synthesised by any animals or plant, we just get it by proxy. (and by the way, industrially raised cattle who don't see the light of day are supplemented in B12 just so you don't have to) So to come back to your original question, I have my B12 mainly from: - Marmite (if you fancy that, but I would understand if you disliked it very much) - Some supplements flakes to put on my salads (byproduct of beer I believe, something like Engevita). It doesn't look like it but I actually enjoy it on my greens (lettuce, cucumber, or any salad) - The very occasional meat/fish. I'm neither vegan nor vegetarian, but I changed my diet to consider these as a treat.
