I found out back in February, by accident that my B12 level has been 212 (180-1000) for the last four years. As part of my plan to get that, Vit D, Ferritin etc all in normal or better range, I started on supplements.
I had a B12 check on 26-6 at the doctors but heard nothing so went in and got a copy of the results. My B12 results are now 1409 (180-1000) so well over. The notes underneath say, over replaced, pt taking supplements does not wish to stop. That is not at all true, I just wanted to get to the higher end of the range and no-one has asked me if I wanted to stop or cut down.
Anyway aside from the lie, I have stopped taking B12 but want to know what a good maintenance dose would be. I have a bottle of 5000mg tabs left so can cut them up but don't know what to take.
