I think the only possible danger come when take vitamin K together with coagulation (clotting) drugs, but only together. i think it has been debunked that vitamin K would be risky on generally in people with blood coagulation issues, many says still it as risky
Vit K1 is specifically for blood clotting. When I had to stop taking all supplements because of strange and deeply unpleasant reactions, I accidentally cut into the upper part of one of my fingers while slicing up my daily ration of cheese for protein (wasn’t tolerating meat at that time, either), and it bled alarmingly, and for a very long time. It was like I’d cut an artery ….. great gushers of blood that just wouldn’t stop. It went on for almost 2 hours. It looked like I'd slaughtered farm animals in my kitchen and bathroom, based on the great wads of gauze, kleenex, Telfa pads, toilet paper etc in the trash bins.
I realized that I somehow had to add at least
some K1 back into my laughable and very restricted diet, and I found some liquid drops online that have worked like a charm, and haven’t caused any negative response.
I haven’t cut myself since, but I have no doubt that it wouldn’t be a repeat of the hemophliac-like response
All those 3 different forms do different things i think, so all important to take and not just MK-7 for example.
As far as I can tell, the two most critical forms of K2 are the subsets of Vit K2, MK-4 and MK-7. MK-4 has been dismissed by online health bloggers and researchers for years in favor of MK7, which was regarded as the gold standard for transporting calcium to bones and teeth as opposed to arteries and other soft tissues, as well as promoting the regrowth. rebuilding, and healing of bones.
As it turns out (and I’m sure
that wheel will turn, yet again), MK4 is actually far more potent in terms of calcium transport and proper utilization than MK7, and has even been found to be effective long terms in dissolving aortic calcium deposits. It has a short half-life, about 4 hours I think, as opposed to MK7 which has a half-life exceeding a full day.
So it seems that to be safe, we should be taking all three of those primary forms. The K vits, as another poster here has noted (forgive me, too fatigued today to go back thru posts and give full credit, but as they say at awards shows, “You know who you are”), are not dangerous if taken in high quantities, and are measured in micrograms. I take about 4000 mcgs of MK4 and 100 mcgs of MK7, largely because it’s more expensive and it takes a
loootttt of drops to get to 100 mcgs. I try for 2x a day, but usually just manage 1x a day.
I also take liquid Vit D3, which I’ve managed to edge up considerably from my starting dose. I’m at 9000 mcgs now.
Both the K vits and D3 are best taken with some form of animal fat for max absorption. I use olive oil or sometimes butter.
Hope this helps. It's
so confusing to plod thru the battles of the bloggers and research papers and sites that are selling one or the other......
EDIT: I forgot to add that Vit D3 should not be taken at the same time as the K7 and K4. I generally separate them by about 12 or more hours, if possible. All of them are potentiated and better absorbed with a little fat.
There. Definitely done.
