Vitamin K2 helps regulate calcium in tissues so that it strengthens bone calcification while preventing its accumulation in blood vessels and kidneys, as calcium accumulation in the arteries poses a great danger for heart patients, which may cause a heart attack. The role of vitamin K2 is to direct calcium to where the body needs it (withdrawing it from the arteries and depositing it in the bones by activating two types of important proteins such as Osteocalcin and GLA). This vitamin helps to improve the health of bones and teeth, reduce the risk of osteoporosis and fractures, in addition to reducing the risk of heart attacks. It is also considered a good fighter against cancer, especially liver and prostate cancer.
