How does vit k work to unclog arteries? & how much would you take daily, 500mg, 1000mg? how much d3 w/it? can't take crestor, or lipitor.

Nothing specific: Vitamin K is one of the co-factors in the function of a protein that helps reduce calcium buildup in arteries. Some studies in patients with K deficiencies note that normal K levels help avoid the buildup. It does not "unclog" anything but may help avoid the problem in deficiencies. Normal dietary K levels are protective. Supplements are not considered appropriate unless a deficiency is found.
