B12 Too High


dube

Recommended Posts

dube Contributor

Bloodwork came back today with my b12 at 1933 and it should be under 928. I have been taking b12 sublingual 2500 mcg for over a year, daily. Sometimes missing a day...does this mean I'm taking too much?

Someone told me supplements cannot increase the counts...which does not make any sence to me, than why take them right?

Yes you should stop taking it. Then have your doctor recheck your levels periodically. Your body may be processing it from your food again and you may not need to take the sublinguals any longer but if your levels drop to a low level like 500 or so then start the supplements again.

The reason why you take sublingual is to make the counts go up in your blood correct?

Jestgar Rising Star

yes, taking any vitamin should make the levels increase in your blood.

Wait so B12 is a vitamin you can overdose on...??

I'm kinda jealous......my b12 count was 125 which they called "freakishly low" at the dr. I started taking the shots :(

b12 is not toxic (that I could find when I googled). Since it's water soluble it clears out of your system pretty quickly when there's too much.

Not according to the NIH. However if your levels are very high you are wasting your money.

Health Risks from Excessive Vitamin B12

The IOM did not establish a UL for vitamin B12 because of its low potential for toxicity. In Dietary Reference Intakes: Thiamin, Riboflavin, Niacin, Vitamin B6, Folate, Vitamin B12, Pantothenic Acid, Biotin, and Choline, the IOM states that "no adverse effects have been associated with excess vitamin B12 intake from food and supplements in healthy individuals" [5].

Findings from intervention trials support these conclusions. In the NORVIT and HOPE 2 trials, vitamin B12 supplementation (in combination with folic acid and vitamin B6) did not cause any serious adverse events when administered at doses of 0.4 mg for 40 months (NORVIT trial) and 1.0 mg for 5 years (HOPE 2 trial) [62,63].

Thanks everyone! I just went off the 2500 B12. I think I was just overdoing it...

were you taking METHYLcobalamin?

I would think stopping for a little while, and then maybe once a week.

There really is NO upper, unsafe limit.

good luck

No I was taking cyanocobalamin 2500 mcg's subligual. My vitamin specialist said I should take methylcombalamin instead if I choose to go back and continue taking them.

      Looking for help sourcing gluten-free products that do not contain potato or corn derived ingredients. I have other autoimmune conditions (Psoriatic Arthritis and Sjogrens) so I’m looking for prepared foods as I have fatigue and cannot devote a lot of time to baking my own treats.

      I am so sorry you're going through this. It's completely understandable to feel frustrated, stressed, and disregarded after such a long and difficult health journey. It's exhausting to constantly advocate for yourself, especially when you're dealing with so many symptoms and positive diagnoses like SIBO, while still feeling unwell. The fact that you have been diligently following the diet without relief is a clear sign that something else is going on, and your doctors should be investigating other causes or complications, not dismissing your very real suffering.

      It is just so sad that health care in the United States has come to this.  Health insurance should be available to everyone, not just the healthy or the rich.  My heart goes out to you.  I would not hesitate to have the test and pay for it myself.  My big concern would be how you could keep the results truly private.  I am sure that ultimately, you could not.  A.I. is getting more and more pervasive, and all data is available somewhere.  I don't know if you could give a fake name, or pay for your test with cash.  I certainly would not disclose any positive results on a private insurance application.  As I understand it, for an official diagnosis, an MD needs to review your labs and make the call.  If you end up in the ER, or some other situation, just request a gluten free diet, and say it is because you feel better when you don't eat gluten.      Hang in there, though.  Medicare is not that far away for you, and it will remove a lot of stress from your health care concerns.  You will even be able to "come out of the closet" about being Celiac!

      Yes, I've posted a few times about two companies: Request a Test and Ulta Labs. Also, pretty much we can all request any test we want (with the possible exception of the N protein Covid test and I'm sure a couple of others) with Lab Corp (or Pixel by Lab Corp) and Quest. I much prefer Lab Corp for their professionalism, ease of service and having it together administratively, at least in DC. And just so you know, Request a Test uses Lab Corp and Quest anyway, while Ulta Labs uses only Quest. Ulta Labs is cheaper than Request a Test, but I am tired of dealing with Quest, so I don't use them so much.

      PS - I think you meant this site, but I don't believe it has been updated in years: http://glutenfreedrugs.com/ so it is best to use: You can search this site for prescriptions medications, but will need to know the manufacturer/maker if there is more than one, especially if you use a generic version of the medication: To see the ingredients you will need to click on the correct version of the medication and maker in the results, then scroll down to "Ingredients and Appearance" and click it, and then look at "Inactive Ingredients," as any gluten ingredients would likely appear there, rather than in the Active Ingredients area. https://dailymed.nlm.nih.gov/dailymed/
