I have another quick question:

I do not know if I have pernicious anemia. That is, I do not know if I lack Intrinsic Factor. Do you know how much of B12 gets absorbed if a person does NOT lack Intrinsic Factor? For example, if a person who does not lack Intrinsic Factor took a 1000mcg methylcobalamin sublingual pill (but swallowed the pill and didn't absorb it under the tongue), do you know if that person would absorb MORE than the 10mcg (or 1%)?

I hope my question makes sense.
