[|Human|] I m on 5mg of Coumadin for DVT. I recently had an Echo and it showed slight calcification of aortic valve, so should I be on Vitamin K2 and if so how much and I have read it should be MK4 not MK7? Is this true, K1 thins the blood and should not be used with Coumadin, but MK4 has nothing to do with blood thinning, but only with calcium regulation?
[|AI|]  No form for vitamin should be taken while you are on Coumadin analogue.  Also, the calcification on aortic valve is age related degeneration and no studies throughout Europe, America or Asia, have found it to reverse with vitamin K analogue, it's a fad and not backed by scientific data, so as a cardiologist I would ask you to refrain from it, as there is no evident benefit, and in your case it can harm.
