Arterial Calcification Reduced with Vitamin K2 Intake

A new study published in the journal Atherosclerosis demonstrated the association of high dietary vitamin K2 consumption with reduction of coronary calcification in humans.

Researchers at University Medical Center Utrecht, Wageningen University and Erasmus Medical Center Rotterdam investigated whether daily consumption of natural phylloquinone (K1) and menaquinones (K2) might be related to the extent of calcification within the vasculature of 564 healthy post-menopausal women.

This study was undertaken to examine the hypothesis that natural vitamin K plays a crucial role in the prevention of heart disease. Results indicated that high consumption of natural vitamin K2, about 45 mcg daily, was associated with 20% decreased coronary calcification as compared with low consumption of K2, of about 18 mcg daily. For vitamin K1 no such correlation was found.
