Escape,

Not having a stomach is like having "pernicious anemia." You don't have either the stomach acid or the intrinsic factor.

So the treatment would be the same as for one with pernicious anemia. Standard is 1000 - 2000 mcg oral or shots.

Buttons,

Sorry if you've already answered this, but has the thyroid angle been thoroughly explored?

Your case is certainly complicated. Any one of three or four conditions could cause your problems, and except for the spider bite , they often occur in the same person.

Regardless, what the heck. More methylcobalamin can't hurt. And make sure you are getting the other nutrients. They're all necessary, and some work very closely together.

I wouldn't take anything else with my B12, not food, not supplements, not meds.

A small minority find themselves wired by their B12. Those often decide to take it in the morning.

Regarding the veterinarian angle, when an RN friend and I were doing a huge amount of reading on B12 years ago, it was much easier to find good information regarding livestock than people.

It pays to have livestock healthy.

Fortunately B12 is easy to get, so we don't have to raid the livestock cabinet.
