Vitamin K2 helps regulate blood clotting, bone metabolism, and blood calcium levels.  It helps strengthen bones and teeth and improves heart health by preventing calcification of  arteries.  Recent studies have shown patients with the highest levels of vitamin K2 were 52% less likely to develop artery calcification, showed reduced risk of developing peripheral arterial disease (PAD), and had a 57% lower risk of dying from heart disease.  Vitamin K2 has antioxidant properties that may help protect against cancer and suppress genetic processes that lead to tumor growth.
