How can I be low on B12?
I've been primal for almost three years. I had been taking B vitamins for a while, but since my diet has been really great and I've added in weekly liver consumption, I stopped.
My doctor just let me know that my labs came back and my B12 levels had dropped more than half since my last test and I was now slightly deficient again. He advised adding the B supplement back in.
HOW can this be?!?! I eat meat every day and make a chicken liver pate that I eat regularly.
If your stomach is compromised in any way, it can interfere with the production/absorption of it.

I have an absorption problem... I use injections
Another vote for absorption issue, which I have as well. I take a sublingual supp...my first experience with a B12 injection was not so pleasant, not something I'll do again.
Thanks everyone. I don't have classic pernicious anemia - or at least I didn't about 6 years ago when I was tested.
I do have a crappy stomach - so maybe I just don't absorb well. Begs the question, what else don't I absorb?
If our guts are so darn leaky, why doesn't the B12 leak through, too? Just sayin'.
If not straight out problems with intrinsic factor, you could be low on some of the co-factors.
This is lengthy, so maybe skip to the later bits where they talk about the co-factors.

Check to make sure you don't have Hashi's! B12 deficiency can be one of the symptoms, as B12 absorption is one of the many things that can go wrong in this illness.
A common culprit are acid reducers people take for heartburn. The acid reducers can effect what our small intestines are able to absorb. Some medical conditions can cause it like Crohn's or Celiac (both small intestinal diseases) and autoimmune diseases like Lupus or Grave's Disease.
If a deficiency of B-12 deficiency goes on long enough, it can cause a neurological condition called peripheral neuropathy, so make sure you do your best to figure out why it is you are low!

If I recall correctly, my doc checked for all the autoantibodies last time he checked thyroid stuff - all came back negative. Thanks though!
