dr wants to start 1000mcg of b12

[Mccrae]

b12 deficiency in United States

My results 206 range (211-911)

I am also hypothyroid and going through perimenapause.

Any suggestions on types of b12

How far to take apart from synthroid?

The dr mentioned a side effect of jitters. Definitely don’t want that due to anxiety anyway

Any advice

At that level, it would be expected to start a course of B12 injections.

And to test for Pernicious Anaemia.

The effects of insufficient B12 are far worse than some jitters. (Maybe I've been lucky, but I've never felt in the least jittery from B12.) And several of those effects are result in permanent damage.

Probably the most common form for personal supplementation is methylcobalamin. But don't get hung up on this issue. Get tested and treated adequately.

Is there any other reason for low B12 such as being a vegan?

Suggest you have a look at the Pernicious Anaemia Society forum:

(Even though it is based in Wales, UK, there are members from round the world.)

no explanation. I have literally been tested for everything. Dr won’t do injections just over the counter

If you have Pernicious Anaemia, that will likely not be sufficient.

Have you had an Intrinsic Factor antibody test?

[Mccrae in reply to helvella]

no but wil ask dr

[Mccrae in reply to helvella]

do you mind me asking what symptoms you had with low b12 physical and neurological so I don’t feel crazy

I'm atypical. I was getting some severe pain and just grabbed at B12 without testing.

After a while, I *think* it helped.
