Vitamin K is a fat-soluble vitamin stored in the fat tissue and in the liver. The name “K” comes from the German word “Koagulationsvitamin”. This vitamin helps in blood clotting and coagulation of blood.
Vitamin K is of three types – Vitamin K1, Vitamin K2, and Vitamin K3.
It is found mainly in plants, especially in green vegetables,
Vitamin K1 helps in maintaining blood clotting.
Made by bacteria, Vitamin K2 protects the heart by keeping calcium out of artery linings and body tissues. It also prevents osteoporosis.
A synthetic form of the vitamin, Vitamin K3 is not much-needed because it can cause toxicity in infants.
What are the health benefits of vitamin K
• Helps in blood clotting
Glumatic acid, the acid that causes carboxylation, is an important component of Vitamin K. When blood oozes out, carboxylation makes the blood stick to a nearby tissue. This clots the open wound and prevents excess blood from flowing out.
You can recognize if a person is deficient in Vitamin K or not by checking his or her symptoms of menstrual bleeding, nose bleeding, etc.
• Helps in formation of healthy bones
Vitamin K helps in the formation of healthy bones by blocking the over-formation of osteoclasts, which take away minerals from the bones and deliver them to other bodily functions. This process is demineralization. Over the due course, this process can leave bones depleted of minerals and having the disease called osteoporosis.
• Vitamin K has Anti-Inflammatory properties
A normal level of Vitamin K reduces the release of glycoprotein interleukin-6, a component that causes inflammation in the body.

• Prevents Calcification
Calcification is a process that builds up calcium inside tissue within the body, leading to cardiovascular diseases. Vitamin K contributes to the process of carboxylation and thus prevents calcification. GLA Protein (called MGP) is formed in the process helps in the tissue formation of calcium. A person with lack of Vitamin K is at a risk of suffering from stroke, atherosclerosis and other cardiovascular diseases.
