Definitely take the K2 (or get it via diet) if you’re taking D3.
Organ meats, egg yolks and some hard cheeses have K2. You know, all those things we’re told not to eat or we’ll have a heart attack? Turns out that advice may have been misleading.
I take Thorne’s drops for K2 (MK4). And something from Jarrow whose name escapes me right now that’s a bone building supplement that has MK7 and a bunch of minerals besides.

Yes, I have tried it and it seems to work.
IIRC, John Cannell MD hawks his D3 with K2, Boron and magnesium.
There was an article in Family Practice News a few years ago. It mentioned blacks taking D3 supplements getting a lot of calcified arteries in larger vessels, e.g. aorta and carotids.
