B12 levels too high?
I was diagnosed with B12 deficiency about 2 years ago. I was very ill by the time they figured out what it was and it appears to have left me with a bit of nerve damage and I have had all kinds of health problems since!
Anyway I started B12 injections straight away, I have them every 12 weeks. I recently had my levels checked and I've been told they are abnormally high.
What's confusing me is, the nurse who gave me the blood test said she didn't think it was necessary to check my levels, as if I was having too much B12 it wouldn't cause me any harm as the body just gets rid of it. HOWEVER when I went to see a doctor a few weeks later he said I should have my B12 injections less often (every 4 months, or maybe less), and that I need another blood test in a few months to check they have gone down as too much B12 can be harmful.
From everything I have read about B12 I have never heard that too much is harmful, I thought that your body just got rid of it. So why on earth do I have an absurd amount of the stuff in my system, to the point where it could be dangerous? my blood test to check my levels was just before I had my injection too, so that would be at its lowest!!!!!
I am due to have my B12 injection next week and I am not sure what to do. Who is right... the nurse, or the doctor? anybody know?
