A member asked:
I have to be concerned because my b12 level are high, and i don't take any vitamin or b12 suplements ?
A doctor has provided 1 answer
Might be serious: I am sorry to tell you that high B12 levels can be a sign of serious health problems including liver ; kidney disease, myelproliferative disorders including leukemia ; polycythemia vera ; hypereosinophilic syndrome. High intake of B12 does not cause these. It is important for you to be evaluated to find the underlying cause. See http://healthyeating.Sfgate.Com/high-vitamin-b12-mean-9057.Html.
