And that link from pabb (sorry friend), has some errors.
Cyanocobalamin is not in food naturally (it may be present in fortified foods and added chemically).
Natural cobalamin is not the cyano version as stated in that website.
If you cannot absorb cobalamin from food, because you cannot break it out of the proteins it is associated with, or you are lacking intrinsic factor, you should still be able to absorb it passively if you take a high dose on an empty stomach.
Your alternative is to use hydroxycobalamin or compounded methycobalamin by injection, or the patch.
I think time has shown that oral sublinqual absorption is not reliable. I tend to think nasal would face the same problems.
