Does anyone know if a celiac/gluten sensitive can have high B12? I know we are meant to have low B12 but what if it is abnormally high – is this another form of malabsorption of it, do you think? Any idea what we do about it? Thanks for any help.
If you are referring to high levels in the serum, remember that serum levels fluctuate greatly from day to day and with supplementation. Sometimes serum levels show up high with supplementation. This does not mean a toxicity. B-12 levels are best measured in the cell itself. Not to say that it isn’t possible, but I have not seen a single case of high B-12 levels in 12 years of practice.
Thanks, I wonder why I keep finding high B12 results here in the UK then with my patients?! Admittedly serum as we can’t get Spectracell here yet – prohibitively expensive but I’m working on it. They are not on supplements. Odd.
