A member asked:

Could taking a b complex vitamin daily scew the results of an mma test to test for b12 deficiency?

A doctor has provided 1 answer

Yes.: Your MMA should be normal if you are taking a B complex vitamin that contains B12 and you do not have pernicious anemia. I can't think of a good reason to check your MMA if your B12 level is normal.
