Hope, if you were "normal" you wouldn't be here.

I guess you are not getting my point:
Here is something else to read that is longer and perhaps more
persuasive:

Some doctors call very low B12 levels normal, because they haven't kept up with newer protocols.

Most nutrients when tested for (if at all) do not show accurate
predictive levels. The ranges are arbitrary, and in the very low and very high readings may be helpful. But the readings are not
accurate or useful inbetween, because people vary genetically in how they handle nutrients. Some need more than others.

I would like to point out...that you would not be looking on the net if you were "normal". You are having some kind of problem that the medical arm is not helping you much.

Remember that the 4th leading cause of death in this country is misapplication of prescription drugs. There are always tradeoffs with them, some are hidden and don't appear right away.(B12 is stored in the liver for up to 5 yrs and can take that long to become depleted) The sudden ones are easier to deal with, but still tricky.
