What Is Vitamin K?
Vitamin K is a family of fat-soluble vitamins, called K vitamers, that exists in three forms:
- K1 is a natural form found in plants (phylloquinone);
- K2, found in some animal foods, is synthesized in the intestine (menaquinone); and
- K3, is a synthetic form that must be activated in the liver (menadione).
Vitamin K is essential for the formation of clotting factors in blood and bone proteins and serves as a cofactor in the production of proteins that regulate blood clotting.
Q: What are the clotting factors that require vitamin K in the regulation of blood clotting?
A: The clotting factors that require vitamin K in the regulation of blood clotting are factors II, VII, IX, and X. Low coagulation factors on blood assay indicate an altered secondary coagulation disorder that is characterized by impaired clot formation.
Each coagulation factor must be present in sufficient quantity in order for normal clotting to occur.
