WebThere are indications that high serum folate levels might not only mask vitamin B12 deficiency, but could also exacerbate the anemia and worsen the cognitive symptoms These potential negative health consequences are not well understood and warrant further research [1,9]. [. In a significant number of people high levels of B12 can cause a functional B12 deficiency (your body reacts to the high levels of B12 making the mechanism that allows B12 to get into your cells much less efficient so you are deficient at the cellular level though the levels in your blood are high. In addition, most trials have included other B-vitamins (frequently at doses well above RDA levels) and sometimes other nutrients, making it difficult to disentangle the effects, if any, of folic acid alone. Both results give the same interpretation (internal Mayo study), therefore, RBC folate quantitation is not recommended. The usual reference range of serum folate is 2.5-20 ng/mL.
