Do you have an opinion about whether Vitamin K2 should be used along with Vitamin D3 supplementation?

What's the best quantity/form to supplement it in? (In your opinion.) Some guy on Amazon compared a bunch of K2 supplements and recommended this one, but it has worrisome negative reviews.

Can you save me the time of having to form my own opinion by giving me yours? :P

I've been eagerly waiting for the analysis and conclusion to your Magnesium experiment #2 When will that be out?

Whenever it's done; I'm probably going to run out of placebos within a month or so, and while I still have a ton of magnesium powder (not sure how I wound up buying so much), I don't think I want to make additional batches of placebo, since it's already run long enough.
