How does vitamin K1 work?

Several parts of your blood clotting system require vitamin K1 to work properly. The process by which your blood clots requires several proteins called clotting factors. Each clotting factor speeds up a single chemical reaction in the multi-step clotting process. Without vitamin K, some of these factors do not carry out their particular chemical reaction and your blood does not clot. Some people do not get enough vitamin K1 because they either don't get enough in their diet or their intestines do not absorb it from their food. These people have difficulties with blood clotting. Vitamin K1, also called phytonadione, by mouth or injection provides the necessary ingredient to help blood clot.
