It does mention, when taking a vitamin D supplement, that you must take 200mcg of vitamin K2 to prevent a build up of calcium in the blood which could cause arthritis. If possible, getting a blood test to determine your D levels is likely a good idea. The levels that you should have are mentioned. 5000 IU each day is also mentioned as a reasonable amount of vitamin D to take. I take D3 which I think is the one usually recommended.
It looks like a very interesting article - i’ll have to print it out to read it fully. I also take D3 but it’s the first time I’ve read of the need for K2. Perhaps because the amount recommended is fairly high?
Thank you for posting this.
Thank you for this very interesting information. I’ve been doing some research into Vitamin D and this article is up there with the best. I’ve been adding K2 to my vitamin D supplements for the last week and feel much safer for it. According to everything I’ve read, it’s perfectly safe to take K2 with DOACs, though not with Warfarin.
Thank you to you, Auriculaire and others on here for enlightening me. My o.h. and I have been tested and discovered to be deficient and insufficient - who would’ve guessed that something as simple and inexpensive as a couple of vitamins could likely make all the difference?
I've been taking 1000-2000 dosage of D3 for several years now for AF reasons.
I take vitamin D3 alongside vitamin C. I was getting colds and flu every year, but have been clear for the last two years since supplementing with these.

Thanks very much for the link. We've both been taking vitamin D for a few weeks now having read similar evidence; we'll now consider adding vitamin K2 (although I need to check this as I'd also read that this shouldn't be taken when on warfarin, so I need to be sure it's okay for when taking other oral anticoagulants, as I am, such as rivaroxaban).
Out of interest, there are some who question the need for extra vitamin D and call it "a pseudo vitamin for a pseudo disease". There is a definitive study being published later in the year, I gather:

Health line Vit k - also gives a very comprehensive article on the pro and cons of Vit k. Reading it I'm goosed, the pun is real. A major source is Goose Liver and other Offal. Eating a mostly plant based diet I do get K 1 which is converted by stomach bacteria into more useful K2. But it is an inefficient process. Fermented foods are another source but i find the downside is the quantity of salt.
As all these articles always say- more research needed.
Good excuse to have fois gras next time I eat out! I am always conflicted about this because there is no doubt gavage is cruel. Usually I resist the temptation.
Thanks for the info.
Thanks Engmac, your contribution is valued as usual!
I’ve said before in posts about taking separate vitamins, it not in usual for one to need another to assimilate into the body. I saw a post on Facebook page, someone taking a high dose vitamin D gave them self an irregular heartbeat from it! We need our blood levels tested to make sure we get the right dose for each one. Mean while a good multivitamin and mineral supplement!
Vit D is not actually a vitamin. It is a secosteroid hormone. One of the reasons for vit D deficiency being so widespread is sun avoidance and the use of sunscreen when in the sun. People are not building up any reserve in summer in countries where vit D manufacture by the skin is impossible for much of the year. Nor are good sources of vit D such as herring consumed widely anymore outside of Scandinavia. Farmed salmon is apparently lower in vit D content than wild fish. The article linked to today is very important as it reports on many studies related to covid but also points out what a "natural" level of vit D is by reference to tribal communities in east Africa. Given the refusal to do wide scale testing and supplementing by the NHS it makes it difficult for people to self treat but it is far more likely that most people are under supplementing rather than over supplementing.
What concerns me is high levels of calcium floating round!
It's wrong to say you can't take Vit K2 with warfarin. I believe it's essential with warfarin as it helps stabilise your INR. INR variability is caused mainly by variation of Vit K in the diet. If that can be stabilised, then INR is stabilised as well. Taking Vit K, or preferably K2, every day as a tablet helps even out any variation in Vit K in the diet.
I take a 90mcg K2 tablet every day with warfarin. My INR is in range 2-3 97% of the time (I had a wobble early in lockdown!).
I agree that Vit K generally and K2 specifically are essential for health and the prevention of atherosclerosis. Too many people on warfarin are advised to avoid food rich in Vit K which is exactly the wrong thing to do.
I am confused Vitamin K makes the blood clot more easily, is that a good thing if you are on anticoagulants? I take vitamin D for my bones
My brother in law is on warfarin and thinking of changing to apixaban and he has been told not to take any K supplements as it makes the blood too thin and therefore dangerous. He has been eating a lot of lettuce lately and he was told by the hospital that this contains K and his INR was far too low.
This confuses me as I thought if someone has a bleed they give vit K to help clot the blood
Vit K on warfarin does not make blood "thinner", it makes it "thicker" by reducing the effect of warfarin. In other words, INR will drop.
I think the advice your brother has got is very poor. You must have Vit K in your diet for the reasons set out above. He can eat as much lettuce as he likes as long as it's a consistent amount. The warfarin can be adjusted to account for this.

Vitamin D and K2 - is it ok to supplement with K2 when on anti-coagulants?
