I have had high Vit B12 levels for a couple of yeas. 1900 usually. My cholesterol, triglycerides, sugar are all in line. I take blood pressure meds to keep a 118/58/54 (a normal range of pressure). I take CoQ10, niacin, lovaza, 20 mg of simvastatin, 100mcg of Levothyroxin and 600 mg of alpha lipoic acid and Metganx(both for idiopathic neuropathy, plus an aspirin a day. Any thing you see that would cause me to have that high b12?
