I have never read about B12 causing blood clots. Could you share the article or link to where this information is?

Wow, that sure is an 'interesting' article.

"Excess vitamin B-12 may cause the heart to stop pumping properly, leading to symptoms of heart failure, according to Drugs.com. "

The only reference they give for this piece of fiction is saying that it is mentioned somewhere on Drugs.com. When I looked up cyanocobalamin on that website, they list a plethora of potential side effects (most of which are actually symptoms of deficiency rather than side effects of vitamin B12) and the entire list is prefaced with the words "Incidence not known" which means there is not any scientific data backing up the list.

"Vitamin B-12 injections are more likely to cause immediate problems to the heart because the vitamins are administered directly into the bloodstream."

B12 injections are given into a muscle. They don't go directly into the bloodstream. The reason they aren't generally given directly into the bloodstream is because the body can't retain as much if given that way, not due to any particular risk of side effects.

"Excess vitamin B-12 can damage liver and kidney cells, leading to symptoms of liver and kidney failure, according to Drugs.com."

Again it's another nebulous Drugs.com reference and this statement is only true if the person has pre-existing liver or kidney problems. If you have those pre-existing problems, you have much more than a simple vitamin deficiency to deal with and would really need to be under a doctor's expert care for treatment.

"Excess vitamin B-12 can lead to formation of blood clots in major blood vessels."

There's not even ANY reference given for this statement. No clue where they got it, but it's clear that whoever wrote it is completely unfamiliar with the subject to begin with.

My recommendation is to keep reading about B12. You will invariably run across additional articles with false or misleading statements, but as you read more about the subject you will be able to figure out what is a load of hooey and what is accurate.

The good news is that I have never seen any *scholarly* articles written about B12 that mention any increased risk of blood clots or stroke.

B12 is generally recognized as safe and actually has no upper intake limit. It is a water-soluble vitamin which, if taken in excess, is simply excreted through the urine.

I have never heard of this . What I do notice is that no scientific research or evidence is referred to at all .

It's a load of FUD, scare-mongering woo-woo, fruitloopery of the first degree.

This is a fine example of a clickbait site that relies on spreading fear, uncertainty and doubt.

The way it works is that unsuspecting people, trying to find out about a condition they've been newly diagnosed with, or suspect they may have, will find their site during a Google search. On the site they will find something that scares them.

Justifiably worried, they will turn to other web sites or social media - either to ask if the scary thing is true, or to warn others. That means more people will visit the clickbait site - which is their main objective.

Because everybody that visits the site will give them a small amount of money from the adverts on that page. Indeed, it will be a tiny bit of money, but it soon builds up if thousands of people visit.

The scumbags that run such sites use scaremongering - because that's much more efficient at gaining visitors than posting anything remotely useful or interesting.

They are leeches, who feed on the fears and social consciences of people who stumble upon their garbage.

Come on, why not say what you mean? :-)

Completely agree. I detest the site. Despite some articles actually being OK.

as Galixie says there is no real evidence for the statements being made just vague references to drugs.com.

This is a page from labtests on line

labtestsonline.org/understa... which lists possible causes of blood clots - it lists vitamin B12 deficiency but definitely doesn't list excess B12.

I had to smile :) when it said B12 could have a "detrimental interaction with folic acid" - well fancy that....

Nobody told me 45 years ago that B12 was likely to cause me all those problems and I'm the biggest clot around here.

I've just looked at a site called Lab Tests Online 'Excessive Clotting Disorders'. According to that, LOW B12 is more likely to lead to blood clots due to high levels of homocysteine. Not a medic so can't confirm. Other sites, like Mayo Clinic, don't think there's enough evidence that high homocysteine leads to CVD. (There's a lot about B12 on the Mayo Clinic site, some of it contradicts what I've read elsewhere.)

Were you on a hormonal contraceptive?

Or any other medication, certain meds are known to cause blood clots. But that's weird that you had too much B12 b/c it's a water soluble vitamin so normally you would just pee or sweat it out.
