Vitamin K: The Clotting & Bone Director

Why Vitamin K is the Master of Calcium and Clots

The "K" in Vitamin K actually stands for *Koagulation* (the German word for blood clotting), which hints at its most famous, life-saving job. Whenever you get a papercut or scrape your knee, Vitamin K rushes to the scene to activate the proteins necessary to form a clot. Without it, even a minor cut could cause you to bleed to death. But beyond stopping bleeding, Vitamin K has a lesser-known, equally critical function: it acts as a traffic director for Calcium. While Vitamin D helps your body absorb calcium, Vitamin K ensures that calcium goes specifically into your bones and teeth, rather than hardening and clogging up your arteries. As a fat-soluble vitamin, you must consume it alongside dietary fats (like cooking your greens in a little oil) for it to be absorbed efficiently.
