B12 is a problem because often our digestion is a problem. Fix the digestion problem, fixes the B12 problem.
Aren't you guys leery of patches and other unnatural methods of "healing". They have a B12 injection also, but you won't see me ever take anything like that. Our nutrition should come from our foods, not injections and patches. If you want to break the laws of nature, you're going to eventually pay the price.
