I'm wondering if her B12 was actually higher than 1200. Not all labs will report b12 levels over a certain amount. So basically, their testing will top out versus reporting the actual b12 amount. So anything over X is just disregarded.
Without more extensive testing (more than the B12 serum and homocysteine), it's difficult to figure what's going on with her B12 status.
I guess I would considered a good B12 complex that has all the bio-active forms and a good trace mineral complex.
