I had b12 tested once along with homocysteine and methymalonic acid? Anyway the b12 was out of range high (1100) and the other values were good. I notice an increase in energy from b12 sometimes, sometimes not. My symptoms like orthostatic hypotension seem to resemble b12 deficiency but I don’t think I have anemia. My methionine on a nutri Eval was just at the top of the reference range like maybe it wasn’t concerting. Can anyone tell me what cobalamin mutation I might have?
