Vitamin K Deficiency Linked to Increased Risk of CVD in New Study
Arteriosclerosis, Thrombosis, and Vascular Biology, the journal for the American Heart Association, just published an 11-year study that draws a clear line between vitamin K deficiency and an increased risk of coronary heart disease.To date, 19 Vitamin K–dependent proteins (VKDPs) have been described, with important roles in coagulation, platelet function, and vascular biology. Produced in an inactive form, all VKDPs obtain biological activity through the conversion of a glutamic acid residue into glutamate, a complex process requiring vitamin K. “Western populations are not afflicted
