Heart palpitations as a result of vitamin K2 supplementation


Ellie says, “Vitamin K2, MK-4 and MK-7, might
have caused prolonged heart palpitations. Upon stopping it, symptoms mostly resolved
after a week or so. Does that mean that the body is better off
without it? Might increasing calcium intake mitigate this?” And then there’s a link. Okay, I can’t look at the link now because
the number of questions in the Q&A goes up, not down, over time. So, I would say, the calcium is really interesting. I genuinely hadn’t thought of that until you
mentioned it. Even though I’ve heard other people ask this
question, I haven’t had time to look into it, but you raise a good point. So, it is conceivable, for example, that your
bone density has been very low because you have not had the K2 you needed to get the
minerals into the bone. And so when you get the K2, you start loading
the calcium into the bone, but maybe because your whole body is programmed to assume things
were the way they were before you started taking the K2, then it doesn’t adapt fast
enough to normalize your blood calcium, which, by the way, how do you normalize your blood
calcium? You take calcium out of the bone. So, if you have something making calcium go
into the bone—oh, by the way, it’s dependent on the dose, right? So, MK-4 has been studied in high-milligram
doses as an osteoporosis drug because it inhibits bone resorption. If you inhibit bone resorption, you will definitely
interfere with your ability to maintain normal serum calcium levels because bone resorption
is how you do that. So, either you’re giving the nutrients needed
to get the calcium into the bone and the body is just prioritizing that because it’s been
missing them for so long, and your serum calcium drops, or you’re actually creating signaling
stopping bone resorption, and so your blood calcium drops because of that. Either way, taking calcium might impact that,
and I would love to have some anecdotal data on that because there’s no studies on K2and
heart palpitations. There’s just a bunch of anecdotes. So, I would love it if we have some anecdotes
of people saying whether the calcium helps, especially since so much of the K2 stuff is
so skeptical of calcium. Kate Rheaume-Bleue’s book Vitamin K2 and the
Calcium Paradox, I think it’s a great book. Basically, what that book is, is an enormous
elaboration of my 2007 article on Activator X and Weston Price. But if I had written that book, I would have
done things a little bit differently. I think the whole idea of the calcium paradox
that’s in the title is, I think it has merit. There is some data indicating that calcium
supplements might worsen the risk of heart disease, but I think that the conclusions
are a little—I think they’re way too anti-calcium, and I think there’s too many people out there
taking K2 who have it in their heads that calcium supplements are bad, and look, calcium
supplements are bad compared to getting enough calcium from food. A huge portion of those people are not getting
enough calcium from food, and getting calcium is more important than where it comes from. I genuinely believe that.
