What is the role of Vitamin K in the body?

Vitamin K plays a crucial role in the body by being essential for blood clotting. This vitamin is necessary for the synthesis of certain proteins known as clotting factors, which are required for the coagulation process. Without adequate Vitamin K, the blood would not clot effectively, leading to increased risk of excessive bleeding during injury or surgery.

While some other options mention important functions related to different vitamins or nutrients, such as calcium absorption and eye health, they do not pertain specifically to the primary function of Vitamin K. The focus of Vitamin K on blood coagulation underscores its importance in maintaining proper vascular health and preventing hemorrhagic conditions. This makes Vitamin K a vital component for normal physiological function, particularly in processes involving the maintenance of hemostasis.
