With that level of malabsorption, those could actually prevent deficiency.
But, for those who are not familiar with this information, that type of malabsorption progresses in some to severe malabsorption due to loss of intrinsic factor. When that is present, B12 from foods or even most vitamin supplements will not help at all. A much larger dose is necessary.

Yes, I could see that as an explanation. (that low stomach acid was a problem keeping me from getting enough B12 or iron from food.)
But if that were it... then why would B12 shots get rid of my low iron?
The shots wouldn't change my stomach acid level, would they?
(I have actually wondered sometimes whether in fact they do... whether once our bodies have a lot more B12 they are again able to do some things they had previously lost the ability to do.)
