Thanks Marlene. Reading this is a relief, i was getting anxious about how it could go so high. Hopefully, the next results will be closer to normal now that she is off the supplement.
As a supplement she was taking Methylcobalamin, which is the bio-available form of B12. In the meanwhile, I have also got her Thorne Resesarch Methyl Guard, which has methylfolate and B6 as well. But she can try only once B12 level returns to a mid-normal level of around 500, as you have suggested.
Incidentally the hematologist says that transfused pRBC contain sufficient B12, and there is no need to supplement with B12, I am just wondering if the high levels could be a combination effect of the transfusions & supplements.
