B12 blood level

Hello, I need to reduce my B12 by roughly100 pmol/L. Does anyone know how to do this? Strict vegan diet?  How long, on average would it take someone to reduce their B12 levels by 100 pmol/L?

Hey Deindre.

Check your B12 supplements. The following is just one possibility.
If it says, Cyanocobalamin you may react to the Cyanide portion
that binds with your free Potassium in your body, thus making
Potassium Cyanide, an extremely potent toxic chemical, releasing
hydrogen cyanide gas, another highly toxic chemical, messing up
your body's ability to utilize oxygen (it's an asphyxiant).
Not everyone experiences this, but it could simulate a homeopathic
effect on certain, while in most the effects are too sublte & gradual to be able  connect it to the Cyanocobalamin, a cheap form of B12 and unfortunately the most commonly used b/c of the price.
Look into Methylcobalamin, if you ever need B12 in the future.
Cheers!

I was wondering how high is your B12 that you only needed to drop it by 100 pmol/L? Because on my wife's blood test it is measured by pg/mL & the normal range is 211 - 946 & hers is high & needs to drop it by at least 1100 pg/mL

My daughter's b12 level is 1900, she is 6 years old. Her BUN/CR, liver function are all normal. She eats a vegetarian diet, not sure how it is so high. Really scared of possible chronic diagnosis. Worried mom who needs help.

Thank you - I have essentially eaten a vegan diet for two straight weeks. A combination of eliminating the supplements, reducing B12 intake for two weeks and the fact that the body is self-rectifying - should mean, no food issues here on in.

There are mechanisms that control the amount of stored B12  in the liver
and circulating B12 in the blood, unless, as I mentioned earlier, there are issues within the  liver or blood interfering with those mechanisms.

You can look up all this and other relative information (with ref. of studies and research cited) at the" Food and Nutrition Information Centre" of
the USDA's "National Argiculural Library".
It is a fairly credible resource for health professionals and consumers.
It's taxpayers' money at work. lol! You might as well use it

  Cheers!

Sorry, didn't mean to say B12 is fat soluble.  Meant to say that although it's water soluble, it's found generally only in animal food and is stored in the liver as fat soluble vitamins are, making it slower to leave the body than other water soluble vitamins.  Bad choice of words there -- oops.  But it will leave on its own.

I believe B12 is fat soluble.  But even so, it will dissipate on its own as you've discontinued supplementation, so I don't think any action is necessary -- it will self-remedy.  Keep in mind that B12 needs to be in balance with B6 and folic acid, particularly, so if it were me I'd just forgo the B12 supplement and ignore the rest.

Hi Niko,

I was definitely taking Methylcobalamin- so we are OK there. When I went to the ND - I was feeling generally awful and experiencing depression (not something that had just come on btw - many years of this). About seven months ago though - I was finally diagnosed with a food allergy. Since eliminating that food - I am 95% better again (so incredible how many ways a food allergy can affect you).

Re: B12. I've had two blood tests and both indicate different levels - but are consistent in that I'm flagged with high levels of B12.

I'm content though knowing I don't react well to higher levels and have all the tools I need to reduce my levels a bit (thank you again for the info).

Thank you also for the head's up re: liver issues. I'll bring that topic up on my next Dr. visit.

Hi again Deirdre. (I'm sorry I mis-spelled you name earlier)

I was thinking about the reasons why and how  B12, a water soluble vitamin
would accumulate in your body and show high levels in a blood test.
My wife worked as a clinical dietician in the past and I asked her.
She says it may have to do with some liver or blood dysfunction/disorder.
What was your issue when you were seeing the ND, at the time, if you don't mind me asking?

After you rule out th reaction to cynocobalamin , then
there's always a chance the lab results were mixed up or wrong, which happens more often than what one may think.

Take care.
Niko

Hi Niko,

Thank you so much for responding :-) I am neither diabetic, nor overweight - just plain silly really. A naturopath some time back suggested I start taking B12 supplements. I quickly developed insomnia and some mild anxiety and stopped the supplements. Some time later I had some blood work done (tested for B12 among other things). B12 was flagged. I assumed because I was low (I was in fact high), so I started taking supplements again. Again the insomnia and anxiety. This time though - after stoppping the supplements, B12 rich food resulted in the same side effects. My Dr. advised me to stop the supplements and reduce my intake of B12 rich food - but I didn't get a clear understanding of how long I needed to do this. Your response gives me a great timeframe.

Thank you again - I am much relieved!

Hey deejo!
Welcome to the forum.
About a month on a vegetarian and some poultry/turkey diet, with a small glass orange juice when consuming B12 richer foods, to neutralize B12
Or potassium supplements (stay below 5000 mg), as it reduces B12 absorption.

Overweight, or diabetic or what?

Take care!
Niko
