Vitamin K plays an important role in blood clotting and bone metabolism in the body. People using blood thinners, such as warfarin or Coumadin should not start consuming vitamin K supplements without first consulting their doctor.1. What is Vitamin K?
Vitamin K is a vitamin found in green leafy vegetables, broccoli and Brussels sprouts. The name vitamin K comes from the German word "Koagulation Vitamin."Several forms of vitamin K are used around the world as medicine. Vitamin K1 is generally the preferred form of vitamin K because it is less toxic and works faster for some conditions.
Vitamin K is most commonly used for blood clotting problems or to reverse the blood-thinning effects of warfarin. It is also used for many other conditions, but there is no good scientific evidence to support most of these other uses.
2. Function of vitamin K
Vitamin K functions as a coenzyme for vitamin K-dependent carboxylase, an enzyme required for the synthesis of proteins involved in hemostasis (coagulation) and bone metabolism, and multiple physiological functions. another form. Prothrombin (clotting factor II) is a plasma vitamin K-dependent protein directly involved in blood clotting. For this reason, people who are taking these anticoagulants need to maintain a consistent intake of vitamin K.
Like dietary lipids and other fat-soluble vitamins, ingested vitamin K is incorporated into mixed micelles through the action of pancreatic and bile enzymes and it is absorbed by cells intestine of the small intestine. From there, vitamin K is combined with chylomicrons, secreted into the lymphatic capillaries, transported to the liver, and repackaged into very low-density lipoproteins. Vitamin K is found in the liver and other body tissues, including the brain, heart, pancreas, and bones.
In the circulation, vitamin K is transported mainly in lipoproteins. Vitamin K is metabolized and eliminated rapidly.

5. Risks after taking vitamin K
Blood thinners, such as warfarin are used to prevent harmful blood clots that can interfere with blood flow to the brain or heart. A sudden increase or a sudden decrease in vitamin K levels can directly affect how this medicine works.
Cholesterol-lowering drugs interfere with fat absorption. Dietary fat is needed to absorb vitamin K, so people who are taking this medicine may be at higher risk of deficiency.
A best method is that our body must always be full of nutrients to be balanced by adding fruits and vegetables. Supplements should be taken with caution when there is a deficiency, and consult a medical professional for supervision.
