Iron deficiency does not produce megaloblastic anemia. If it produces anemia, it produces small cells.

However, whether anemia is present or not, in small or large cell form, some level of iron malabsorption often accompanies B12 malabsorption because insufficient stomach acid contributes to both, and that is a common cause.

Also, it is not uncommon for those tests to be normal when low iron and low B12 occur together. Many doctors do not know that those tests can be very misleading.

I hope you will begin taking daily methylcobalamin. You may have difficulty converting other forms or getting usable B12 to your tissues. It must get there for use and for storage, and getting daily dosing of readily usable methylcobalamin would likely help.

Also, it would be good to continue to read on this forum for other nutrient ideas. And how is your liver?
