Here is my Q&A with Davis at the TYP site on K-2.
Another question that came up in my reading here is the value of adding K-2 as a supplement. Dr Davis has not said anything about it here or in the blog other than the posted article that I can find. I find the article a bit confusing. It starts off by mentioning that "K" was found to be a coagulant, which I certainly don't want since I am thinning by blood with an 81mg Aspirin daily. I assume that K-2 is safe to use but I find if I can't explain this to someone else logically I am not comfortable with using it.
So where are we on "K-2?" Should we, as a matter of course, add it to our daily supplements, and why?

Lindy--
The reason I've not gone on further about vitamin K2 is because the science nor our experience have not taught us any new lessons.
I continue to believe that K2 supplementation has potential value, but the science sure could use some development. Unlike vitamin D, which you KNOW works when your blood glucose drops, blood pressure drops, HDL skyrockets, mood increases, mentation gets clearer, etc., vitamin K2 supplementation yields no such perceptible benefits. So we need to rely on any data we can obtain or observations we generate in many participants.
Also see a Heart Scan Blog post, Food sources of vitamin K2.
Taking any form of vitamin K does not force blood to coagulate. A deficiency prevents blood from coagulating, but the reverse is not true, any more than filling your gas tank up higher makes your car go faster.
In short, the argument in favor of vitamin K2 remains unclear. I personally take it. I don't believe it is money wasted, given its bone health benefits. And my prediction is that it will prove to be a beneficial agent. But I can't tell you that for a fact. |
