Hey guys, ive been reading these posts and since everyone here seems so knowledgable about B12 i was hoping you might be able to answer a question I had blood work done that showed that i was low RBC count and high MCV and MCH which my dr. thought i could be B12 deficient but it just so happened i started taking a high sublingual B12 suppliment the day that i took the blood test which made my b12 levels over 1400H! So my question is, is it possible that (if i was B12 deficient) that the levels could move up that high after just a few doses of a b12 suppliment?
