Vitamin K is the name given to a group of fat-soluble vitamins that are primarily responsible for aiding blood clot formation in our bodies. In fact, the reason why vitamin K was never named vitamin F (the next logical step after vitamin E) was to emphasize its central role in blood health: the “K” actually stands for “koagulation,” the German word for “clotting.”
In healthier times, deficiencies in vitamin K were rare since traditional diets incorporated a lot of leafy green vegetables – the world’s greatest sources of the vitamin. As processed food began to dominate our dinner tables in the twentieth century, however, deficiencies in this important nutrient, which can lead to easy bruising, nose and gum bleeding, and weakening of the bones, started to emerge. Fortunately, preventing or correcting a vitamin K deficiency is simply a case of eating more whole foods that are rich in it.
