Bone Health and Vitamin K
Studies have shown that vitamin K may activate the protein needed for the development and growth of bones. There is a link between low vitamin K1 and K2 levels and a high risk of bone fractures. Taking vitamin K supplements, therefore, can help prevent bone loss and fractures. Overall, the nutrient plays a role in the maintenance of bone health. But more controlled studies should be done to verify the link. [3]
Blood Clotting and Vitamin K
Some proteins involved in the process of blood clotting require vitamin K. Without this nutrient, the body may bleed excessively when you have an injury. People with blood clotting conditions who are taking warfarin to prevent blood clotting should ensure a consistent intake of vitamin K. In general, the blood clotting effect mainly comes from vitamin K1, but it is also necessary to monitor your intake of vitamin K2. [4]
Heart Health and Vitamin K
In addition to bone health and blood clotting, vitamin K also plays a key part in improving heart health and preventing heart conditions. This nutrient activates the protein needed for preventing calcium deposits in arteries. Otherwise, these deposits would cause plaque to build up and increase the risk of heart disease. Some studies have shown that vitamin K2 is more effective than vitamin K1 at reducing the risk of heart disease and preventing calcium deposits. [5]
