Poll - B12
I take one 5000mcg sublingual once a week.
My B12 was "high" the last time according to the lab sheet and my surgeon's PA (but I am ignoring them)... I don't remember the exact number, and am too lazy to go dig out the lab sheet, but it was around 1250 or so (but under 1300). Will have full set of labs drawn again later this month (4 years, baby!!)

You don't drown by falling in the water. You drown by staying there.
I know that seems like a simple question, but the answer depends on who you ask.
Most labs list the normal range for B12 as something like 211-911. I cannot for the life of me understand why.
When B12 drops below about 550, people tend to get tired and depressed. They may have trouble concentrating and have problems with short term memory.
When it drops below about 400, people start to get numbness and tingling in their hands and feet. That is due to nerve damage. That nerve damage may be permanent.
My experience (and the experience of some other people I know) is that B12 can increase or decrease a lot in a pretty short period of time. I like mine around 1000, higher is OK.

I take sublingual 2,500 each day. I did take smaller doses, 500 if I remember correctly, in the past, but last labs showed low levels.
I dont have the last reading, as I'm away from home, but I think it was in the 300 range.
I'm due for new labs soon and expect it to show improvement.

I did not have mine checked before surgery, but it's interesting that yours was low. I've read a bunch of stuff that says B12 deficiency is rare in the "general population" but I've always wondered if that was true. Since most people never get their B12 checked, how would we know if it's rare or not?

I agree. I think it's much more likely that the "general population" doesn't get tested even semi-regularly and I think they should. Prior to surgery, my vitamin D was undetectable and I'd been working for ages to get that up in the normal range. I've gone from less than 4 to 40 in the last year. I couldn't tolerate large doses of vitamin D (they triggered my epilepsy) but have managed to work my dose up to a fairly substantial dose just lately and hope that trended upward as well. At least with vitamin D, doctors are starting to test more and more people to "just see where they stand" which is uncovering quite a lot of people who need treatment.
