I think everybody - vegans or not - should take a B12 test, because B12 is so important and so many (both vegans, lacto-vegetarians and meat-eaters) have low levels.
This poll won't tell anything about the B12 levels in vegans who don't take supplements, because many of the people who reply may take eg. multivitamins. Maybe we'll have another poll about vegans who don't take supplements later. But after some months, we'll get an impression about how many of our members who've actually had B12 deficiency, including serious cases of irreversible B12 deficiency.
