Clopidrogel and vitamins

[Holiday12345]

Is it safe to take vitamin k2 with Clopidrogel? Does Vit k2 affect clotting like Vit K1 does? I know you have to be careful with Vit k with warfin.

I take k2 with my Vit D3 & magnesium ... I thought Vit k2 was essential for getting calcium into the bones. But don’t want to take it if it is going to interfere with my blood thinner.

Also niacin (Vitamin b3) is this ok with Clopidrogel? (I think it can thin your blood and possibly cause bleeding?)
