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? |
It would all depend on timing. If you took the SL B12 fairly close to the blood draw, it would falsely elevate the value. I have experienced this with get my niacin levels checked. It is actually short lived in the blood in detectable levels. If I took it the night before it would be below the detectable level. If I supplemented in the AM it would be detected. I usually hold supplementation for a day or two prior to testing to get a more accurate measure of what my true levels are.
