Calcium Causes Heart Attacks Without Vitamin K2

Well, here we are again...just over a year later, and another study on calcium supplements suggests it raises the risk of heart attacks. If you're wondering if this is even true, in my opinion, yes it is. However, you shouldn't worry too much about this as long as you're taking vitamin K2.

Instead of repeating myself, please read my response to a similar study last year. The title of the post was Do Calcium Supplements Cause Heart Attacks? and I hope this gives a clear explanation that the evil in this story is not the calcium supplement, but the fact that most people don't get enough vitamin K.

Why? Vitamin K is required by your body to understand where to put all that wonderful calcium. Without it, it'll get deposited into soft tissues (where it doesn't belong) and this becomes a problem when it gets deposited into the arteries (significantly increasing the risk of a heart attack and stroke).

This was totally coincidental, but just yesterday I covered a human study that showed* vitamin K2 in the form of MK-7 at just 180 mcg/day was able to reverse the negative cardiovascular effects of calcium.
(*more like implied, since the researchers didn't measure arterial calcium directly, but measured things affected by arterial calcium like elasticity)

What's particularly bizarre with this study on calcium was that the researchers actually investigated whether a higher intake of calcium might favourably modify cardiovascular risk factors. Am I out to lunch here? While some studies suggest calcium may help with blood pressure and cholesterol levels, calcium has never been used in a clinical setting to reduce cardiovascular risk factors (at least to my knowledge). In fact, I've known for many, many years, it's the opposite, just as the study's conclusion suggests. This gives me the itching desire to put on my conspiracy hat and say this could have been a witch hunt right from the beginning...but I won't go that far in this post.

For anyone taking calcium--and I've said this 1000s of times over the last 5 years or so--taking supplemental vitamin K2 is mandatory! Please peruse the links below and get the full story that mass media chooses to leave out.

If you subscribe to Know Guff, you'd already know this. If you don't, what's your excuse?!

  1. What a waste of time and money. i bet these are the same type of researchers who will publish another study showing smoking causes lung cancer! old news. let's move on.

    1. I see your point. A little extreme, but yes, I can't disagree (I love double negatives).

      What I find even more interesting is that given that vitamin K2's roll in calcium metabolism is nothing new, it blows my mind that these researchers (who apparently consider themselves educated on the matter) didn't even consider measuring vitamin K status.

      This is the problem with researchers who think along the lines of conventional medicine, they look at things in isolation, just as drugs.

      The fact is that calcium is great at improving bone health. From a conventional medical point-of-view, this makes sense--you treat one condition, and accept the fact that there will be side-effects you have to deal with.

      However, prevention of a disease is FAR different from treating a disease. If you take treatment (in this case calcium as a mono-therapy) and apply it as prevention, it just doesn't add up. Preventing osteoporosis is multi-factorial, and if you take an essential nutrient like calcium and use it as a drug (i.e. treatment), you SHOULD expect side effects (e.g. increased risk of heart attacks). However, if you truly want prevention, you've got to take a holistic approach and consider the full picture.

      Anyway, thanks for your comment. I realized that it gave me the opportunity to share a lot more of my thoughts on this hot topic.

  2. Based on the research showing K2's importance in calcium metabolism, i can't believe research continues to be conducted on calcium and cardiovascular disease and vitamin K status isn't even considered! it's actually mind boggling. Thanks for covering this, Lee. I only hope the folks at CBC or CTV subscribe to this blog and get your input next time.

  3. As long as endocrinology and specifics from that discipline are ignorant amongst doctors, few can seek ailment. Doctors aren't alchemists, Latin for 'teacher'... and corporate interests are their knowledge, pretty straight forward. Lest we forget those diluted 'doctors' saying smoking is a beneficiary and lets ignore aids for a few decades...

    Control your pH level
    Look after the mucus membrane
    Raw Vegan Diet
    Understand psychosomatic influence

    DONE. Forget this calcium jargon... Nothing causes a heart attack, except your own miss guided ability to remain calm. The sudden 'hand-to-chest' affray and panicked reaction IS the heart attack, that extra kick of adrenaline, adrenochrome etc IS THE HEART ATTACK, Pill dispensaries, oh sorry, doctors, are only introduced to psychosomatic dis-eases such as Takotsubo cardiomyopathy.

    Studies are limited beyond reasonable repute, a famous real doctor from Harvard did state over 90% of medical studies are full-of-S***, I'm just surprised he was kind enough to leave that possible 10%...
