Just curious - which kind of k2 do you take? I take MK4 and I LOVE it. MK7 didn't really seem to do much of anything for me, but the MK4 makes it possible for me to take the D3 (in which I was badly deficient) and (weird side effect) it makes my teeth feel clean! And I really think I feel old injuries being repaired. I definitely have less stiffness in my joints, particularly my fingers.
