B-12 deficiency recovery: good enough?
Hi everyone, new here, looks like a great resource.
I learned I was low on B-12 about 2.5 weeks ago (lab serum level was 220). Had a variety of unpleasant neuro symptoms, and crazy energy swings (thought I was hypoglycemic). Came on very suddenly.
Since then I have had 3 shots of cyano B-12, 1000mcg each, 2 in the first 5 days, then 1 yesterday (a week later). I'm feeling good improvement already, but have been having some reactions to the shots - more on that in another post.
My doc now wants me to have shots at 3 wk. intervals for the next couple months, then check my levels again. He thought oral supplements in the meantime were a good idea when I asked, but didn't bring it up himself. He had never heard of sublingual supplements. Didn't ask him about methyl.
He's a good doc in general, listens well. But I don't think he's super clued in on B-12.
My main worry is I don't want to drop back down to the level I was at. Before this last shot I had started to feel super fatigued again, thought maybe my levels have gotten low again? How long would it take to use up the boost given in one of those shots?
So if I get a shot every 3 wks, and take 1000mcg sublingual daily, is that likely to be enough to at least hold me steady, and hopefully build up reserves?
Should I be pressing him to do shots more often? Or test me more often?
I've heard some people get many shots daily, then weekly, until their levels are up.
Also: other than celiac test (negative) he hasn't really seemed too interested in tests to find out why I'm low. Claims that the antibody tests for PA are unreliable. Didn't test me for folic acid, HC, or any of the other related stuff, although plans to do that on my re-test in 2 months.
Should I be pressing to do any of that stuff sooner? Would it affect my supplementation plans over the next 2 months?
Thanks, everyone, for your help!
