In the past, the requirements for vitamin K only considered its classical function in coagulation; an RDA was given for vitamin K in the United States (54, 58) and a safe and adequate intake level was given in the United Kingdom (65).

Vitamin K increases the chemical reactions in your body needed for your blood to clot. The more Vitamin K you take, the more chemical reactions your body makes for your blood to clot.
