How Does Vitamin K Work?
Vitamin K aids in the production of several proteins that are required for blood clotting and bone formation, among other things. Prothrombin (clotting factor II) is a vitamin K-dependent protein that plays a direct role in blood clotting. Meanwhile, osteocalcin is another protein that needs vitamin K to grow new and healthy bone tissue.
It is present in many parts of the body, such as the liver, brain, heart, pancreas, and bone. It degrades quickly and is expelled from the body through urine or stool. As a result, even at high doses, it rarely exceeds toxic levels in the body, as can happen with some other fat-soluble vitamins.
Some people refer to it as the “clotting vitamin” that is naturally found in certain foods rich in vitamin K and other dietary supplements.
People who take the blood thinner warfarin are advised to maintain a consistent dietary intake of vitamin K. Otherwise, their medication may become less effective.
