Overview

Vitamin K is a vitamin found in leafy green vegetables, broccoli, and Brussels sprouts. The name vitamin K comes from the German word "Koagulationsvitamin."

Several forms of vitamin K are used around the world as medicine. Vitamin K1 (phytonadione) and vitamin K2 (menaquinone) are available in North America. Vitamin K1 is generally the preferred form of vitamin K because it is less toxic and works faster for certain conditions.

Vitamin K is most commonly used for blood clotting problems or for reversing the blood thinning effects of warfarin. It is also used for many other conditions, but there is no good scientific evidence to support most of these other uses.

How does it work ?

Vitamin K is an essential vitamin that is needed by the body for blood clotting and other important processes.
