A member asked:
Blood work shows excessive amount of b12 >1999. its been 3 weeks since b12 supplements were stopped. how long does it take b12 levels to go down?
A doctor has provided 1 answer
It may not: I'd stop worrying. Some folks have high levels of the protein that carries B12 around in your bloodstream. This may be genetic and in any case, nobody understands it. It doesn't seem to be a problem, especially if you're well otherwise.
