What causes a high serum b12 without drugs or vitamins? a sick liver?
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 and kidney disease, myelproliferative disorders including leukemia and polycythemia vera and 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
