The B12 in off the shelf beef , chicken is from it being injected by farmers (along with all manner of other stuff such as antibiotics).
The truth is that every living being is low on B12 due to soil erosion / over farming. So in a way a meat eater is supplementing B12 by proxy of an animal, where as a vegan is buying a pot off amazon (and in turn able to get a much more specific dose).
