Hi jackD. I checked my calcium, Vitamin D and K supplement pill and it is vitamin K1 that I have in this pill, 40 micrograms, and I take 3 a day at each meal.

The daily suggested amount of Vitamin K is 120mcg. So that level is okay for me.

I was wondering about K2 and I found out from this article that we make in our large intestines. I knew we made it, I just didn't know whidh form. It also talks about calcification of the artieries as you mentioned, b/c of a lack of vitamin K.

This form of vitamin k is also available in some foods.

I am going to have to take some notes about the other things you cite and look into them, too.
