Hi, Several years ago I had to take coumadin for atrial fib. I was required to get periodic bleeding time tests to get my bleeding time in sync with my diet. My bleeding time was all over the place and I would have to adjust the dosage of coumadin almost every time I was tested. The more vitamin K I had in my diet, the shorter the bleed time and vice versa. Because I am a biochemist with several years experience in blood clotting, I became aware of the existence of K2 and started taking it regularly. My bleeding time did decrease a bit, but never deviated from that point on. .What we found was that instead of avoiding any vitamin K, which was their advice then, K2 supplementation made it unnecessary to have periodic bleeding time tests!

One more thing, a common misconception among doctors even now is that vitamins K1/K2 promote clotting solely. This is because the first proteins that K was known to carboxylate (so that they could bind Calcium), were several of the clotting enzymes, factors II, VII, IX and X. We now know that K1,K2 carboxylates many other proteins including two that actually inhibit clotting!

Thoroughly enjoyed reading this article! Thank you for your in-depth research! I take vitamin K2-m7 daily for bone health. When I clicked on the link you provide to Consumer Report Lab to see their list of top picks of vitamin K2, the CRL article contradicts some of the points you make in your post, which was disheartening. Additionally I could not see the list of top brands unless I agreed to a subscription or joined for free after I gave them my credit card info. I would not recommend CRL for your readers. It was not helpful. Your readers will a clear understanding of vitamin K from your post. Thank you.

This is a really interesting and useful blog, thank you for posting it.I’m trying to improve my bone strength by diet and activity so finding your blogs/youtube videos has been really helpful. I’m a big fan of natto not just for health but because it’s so delicious (I won’t deny it’s a bit weird tasting too, but still really nutty and savoury and yum!). One delicious way to eat it is blitzed in a soup – using onion helps to mitigate the smell and removes much of the stickiness. It’s perfect for this time of year too. There are lots of recipes on youtube for anyone who wants to try it. In fact, talking about it is making me hungry – where’s my saucepan!

Hi Margaret,

Just wanting to know if cheddar, swiss, etc. (other hard cheeses) are the same as Gouda and Edam for their K-2 content? Is there something about the Gouda and Edam process that is different.
Also in the US, what is curd cheese? Cottage cheese, ricotta? We don’t see “curd” cheese specifically in our grocery stores.

Thanks you, as ever!

Margaret, thank you for all the great information. I was recently diagnosed with severe OP and am finding your videos and blogs super helpful. What is your opinion about phytic acid in foods interfering with mineral absorption? I’ve been eating oatmeal for breakfast for many many years and taking my calcium supplements with it. Oh, dear. Just learned that’s probably not a good idea.
