MTHFR

Hi Sheila,

Please see my page on MCV Blood Test to see why high MCV is related to Vitamin B12 deficiency EVEN IF you have high levels.


It sounds like you might have the MTHR Genetic Mutation that does not allow you to absorb Vitamin B12 and folic acid normally. You should be tested for this genetic mutation. It's quite common and the treatment is to avoid all vitamin B12 and folic acid that are not in the methyl forms. I carry Beyond B12 which is a formulation that is safe for those with the MTHFR mutation for just that reason. You can have high blood levels and not be absorbing the vitamin B12 when you have the genetic mutation.
