Vitamin K2 plays a crucial role in activating osteocalcin, which helps to bind calcium to bones and reduce arterial calcification. Studies reveal that even a small daily intake of K2 can significantly lower the risks of heart disease and overall mortality, potentially increasing longevity by up to seven years. Despite its importance, K2 is scarce in the Western diet, and the use of statins may further hinder its function, highlighting the need for greater awareness of this vital nutrient.
