vitamin K

Blood coagulation factor

Vitamin K is a fat-soluble vitamin essential for blood clotting and bone metabolism.

The K comes from the German word for coagulation.

Found in leafy greens, it's also produced by gut bacteria.

People on blood thinners like warfarin must monitor their vitamin K intake, as it can interfere with the medication's effects.
