vitamin B12

[JackieOnLine]

I was taking a B12 every day and my labs last fall showed a very high level. the doctor said, stop taking it but someone here - I think Liz - said don't stop, cut down. so I did cut down to a 1000 mcg once a week.
just had a lab test for it and mine is

970 pg/mL and standard range is 193 - 986 pg/mL.

haven't heard from the Nurse Practitioner yet, but I'm guessing that's good and I should stick with one a week?

Personally, I’d add back ONE extra a week. Get it over 1000.

Several of us routinely test over 2000, taking none. No issues with that level.

I would guess my new NP will tell me to stop taking it. She didn't like that I'm currently taking 5000 IU of Vit D3 and have been since last winter - she said I should only take 1000-2000 max.

also, when I mentioned the VSG she said vitamin deficiencies were "more from bypass". uh, yes. but.

also? she is incredibly young but I am trying not to hold that against her. more and more people seem that way to me!

She’s not going to follow you around. Just do what you feel is best. They tell me all the time to stop taking B12 even tho it’s in my file that I do not take any B12. Just what is in my multi and my food. I let that one go in one ear and out the other.

At some point you just stop worrying and say, ok, I considered the problem, this is the best I can do...

"970 pg/mL and standard range is 193 - 986 pg/mL."

It's in range... problem solved

5000 IUs of D daily is what is recommended for people with normal guts. I would continue to take that unless they test your levels and you are super high (I doubt it).

Highlights the difference between normal and optimal.

The vitamin B12 standard reference range is 200–700 pg/ml whereas the proposed optimal range is 500–1300 pg/ml [10]. Higher vitamin B12 ranges have been associated with increased cognitive function, and reflexes, decreased brain atrophy, confusion, weakness and depression

And notice, the lab range is since been adjusted upward.
