I see that your comment is downvoted a shade, but I'd like to know whether it is true or false. Do you (or anyone else) have a citation?

  You could do a quick search but I think common sense should suffice here. How did all the (meat eating) humans survive before b12 supplements were around? Animals surely do not receive supplements in the wild. In the factories is where they are deprived of their natural diet that would provide the b12.

    I agree, but sometimes I hear other theories. One of the other comments said something about unsanitized water providing b12. In the past I've heard that just eating dirty fruit and vegetables had enough b12.

      I suppose those theories are possible and I should do some research. The "normal" way to receive B12 was from livestock eating grass/vegetation that were covered in dirt. In that case, humans would indeed meet their B12 requirements from eating those livestock.
