Vitamin K is a fat-soluble vitamin that is essential for many functions in the body. It plays a critical role in the blood clotting process and is necessary for the synthesis of proteins involved in bone metabolism. Vitamin K is also important for maintaining the health of the heart and the arteries. Vitamin K is found in a variety of foods, including leafy green vegetables, liver, and eggs. It is also produced by bacteria in the gut, and some people may get a significant amount of their vitamin K from this source. Deficiencies of vitamin K are rare, but they can lead to bleeding and other health problems. Vitamin K supplements are sometimes used to treat deficiencies and to prevent or treat conditions related to low levels of vitamin K. However, more research is needed to determine the effectiveness of vitamin K supplements for these uses.
