  1. Hi. That last info graphic is showing a gallbladder as part of the efficient B12 reabsorption process. I no longer have a gallbladder… am I more at risk for deficiency? Thanks.

  2. you should not take cyanocoablamin, it is synthetic B12. Methylcobalamin is better to take as supplement, liquid sublingual work best I think in my opinion and tablet sublingual also work great. Cyanocobalamin contains small amounts of cyanide. No one needs that either.

  3. It's not about the cheapest, but most effective and efficient. If it is true that cyanocobalamin must be converted by our body into methylcobalamin, surely it is wiser to use methylcobalamin. The side benefit is no cyanide.

    This is always the problem where money is involved. Chemically these 2 types are identical apart from the obvious. So why is Dr. Greger in favour of cyanocobalamin?
