I was just wondering if anyone here has ever read the book written by Sally Pacholok, R.N., BSN and Jeffrey J Stuart, D.O. called "Could It Be B12?" They say very often your B12 level simply reflects the amount of B12 you are taking daily. They also say that once you start taking B12, when being tested for B12 levels, it will never be a true test again. Sally posts about B12 in the wrongdiagnosis.com forum.

My B12 level was never tested before I started taking B12. I could not get my doctors to listen to me, as is often the norm, especially with a celiac. So often, we get the run around when trying to get a diagnosis, I was hurting so much and finally I tried whatever I could to stop the hurting. B12 was one of the things I tried. When I finally got a doctor to test my B12 level, I was taking 1200mcg daily of B12 and my level came back at 1237, so my doctor told me my B12 is just fine, not to worry about it. So, now that Mel's came back 2000, and I take 3000mcg daily, I am betting mine would come back high too.

Do you feel there is any truth to their theory?
