A member asked:
Is it bad if my b12 level is above what it's supposed to be?
A doctor has provided 1 answer
It depends : B12 is not toxic so if B12 is high due to taking it, it is not bad. If someone has high B12 without taking it then it may be a sign of serious problems including myeloproliferative disorders or liver or kidney disease. High B12 does not cause these but is caused by them. Further tests are needed to find the underlying cause. See http://bit.Ly/1hvpcy7 and http://mayocl.In/1cmsaf0.
