Vitamin K is primarily used to support blood clotting processes in the body. It plays a crucial role in the production of proteins required for blood coagulation, helping to prevent excessive bleeding. This makes it essential in treating conditions like vitamin K deficiency, which can lead to bleeding disorders. It is also administered to newborns to prevent hemorrhagic disease, a rare but serious condition. Additionally, Vitamin K is important for bone health, as it aids in the regulation of calcium, contributing to bone mineralization and reducing the risk of fractures. It is sometimes used in conjunction with other treatments for osteoporosis. Some studies suggest it may help reduce the risk of cardiovascular diseases by preventing calcium buildup in blood vessels. In some cases, it is applied topically to reduce bruising and skin discoloration.
