Vitamin K, a fat-soluble vitamin, plays a crucial role in the process of blood clotting. It activates proteins required for blood to clot, a vital process that prevents excessive bleeding after an injury.
In addition, it contributes to bone health and regulates blood calcium levels. Vitamin K can be found in green leafy vegetables, broccoli, and Brussels sprouts. Adults generally need between 90-120 micrograms of vitamin K per day.
