Hi all,I have question regarding B12 levels. I have just been to the doctors and he has told me that my B12 levels are too high. He said the normal range is up to 900 and mine is 1109. He told me to stop taking my b-right capsules as too higher level is not good for you. Should I stop taking the b-right capsules and let my levels drop? What is the danger in having high B12 levels? Thanks for reading.

Obviously your doctor does not know much about B12.

Do you know (and does he know) that the ranges used for testing are based on statistics? That is, people are tested in a group and the ranges are taken from that. (they are considered normal "healthy" people--which they may not be.)
There are no studies showing that higher B12 levels are harmful to anyone. Normal people who do not take supplements are not going to show high levels either.
Many people who see benefits from B12 supplements have readings of 2000 or higher.

There are no studies showing an upper limit of toxicity for B12.

Is this what you are taking?

If so it doesn't have much in it to worry about. The B12 level in it is only 100mcg.

In other countries (Japan for example) anyone lower than 500 is treated with supplements. In fact your levels are rather low considering you are supplementing..

I'd suggest you do some Googling, and print out stuff for your doctor to read. He needs some updating.

Hi MrsD thanks for replying. Yes those are the b complex that I am taking. Why would my levels be so high if I am only taking 100mcg? I was taking 5mg methyl b12 but that was last year and I haven't taken them for months and months.

Well, when I had my B12 done a few years ago, when I was NOT taking supplements it was 849.

Your level doesn't strike me as high. Just above the normal range. You could have been much higher and it has come down some if you were using 5mg/day previously. You may just be on the way down.

The B-right is not alarming at all, and 100mcg is below what is used to treat frank deficiency.

I wouldn't worry about it, and I'd ignore the doctor on this one. If you feel well, then just continue what you are doing.
(as long as you have normal kidney functions).

I really am not a fan of doctors who falsely alarm their patients when they don't know what they are talking about.
Sounds like yours is just blindly used to following lab ranges for other things, and has generalized the mental job to include alarming responses to an unalarming situation.
Most doctors don't have a clue about nutrients and testing.
Sounds like yours is one of those.

Look at this one from Quest---

160 considered normal? Blech!

With many vitamin and mineral (esp magnesium) testing, it is the DEFICIENCY that is the
major target looked at. Interpreting them is not always accurate for others.

My B12 level was 1237, and now I am taking more B12 then when the level was done, and I came back at 1013...none of my doctors have told me it's too high. I wouldn't worry about your B12 level, like MrsD says, lots of people are a lot higher than that!!!

Hi. Mine was 2000 and that was after I stopped b complex before it was 1500. I have no idea I think sometimes blood work can be off. My doc said the same thing as you.

I wish I could borrow a little of your B12...mine is 82 and dropping...

Got a copy of my blood work in the mail today. My B12 level at the time of the test, taken about a month after being stricken with PN was 690. I know that is considered normal by many doctors, but is that really OK?

I can't imagine a doctor telling a person that their B-12 level is too high. That doctor knows absolutely NOTHING about neuropathy and B-12.

I take 5000 of the Methyl B-12 every single morning sub lingually. I've been doing this for about 2 years now (ever since I was diagnosed with diabetic neuropathy). I had the burning, the pins and the buzzing. Drove me crazy. I immediately went on the methy 12. I went from 1000 to 5000 after 1 week. I knew I needed it.

To say it has changed me is putting it mildly. It has rejuvenated me. My last testing level was 2000. My doctor didn't even blink because he knows me and what I am on.

He's a body builder and knows all about vitamins. I ran every thing by him. He's also my husband's doctor. He knows I grow my own sprouts, and I make home-made yogurt and he's completely supportive.

He is also very supportive of the vitamins and supplements that I take. I wanted him to know first hand what I take because I have spoken to other doctors, who, when I told them about B-12, looked at me like I was a lunatic and said the following words (I'll never forget them).

"You take B-12???, WHY I WOULD NEVER PRESCRIBE B-12 FOR ANYONE WHO WASN'T ANEMIC".

I will never forget that doctor if I live to be 100.

I told his partner what he said. His partner said "yeah, he's from the old school".

This guy is NOT my primary care physican.

My primary care physician is the best. He listens and he respects us. We can ask him any question about ANYTHING.

And he even hugged me when I went there to pick up samples of Alan's meds.

I am always surprised at how different physicians can be. It's amazing.

Mel....your PCP is a physician, his partner is only a doctor
