What is one function of Vitamin K in the body?

Vitamin K plays a crucial role in the body, particularly in blood coagulation, which is the process that helps prevent excessive bleeding when injuries occur. This vitamin is essential for the synthesis of certain proteins known as clotting factors that facilitate the clotting process. Without adequate levels of Vitamin K, the body may struggle to form clots, leading to increased risks of uncontrolled bleeding or bruising.

In contrast, the other options address functions that are not related to Vitamin K. For instance, enhancing iron absorption is primarily linked to Vitamin C and certain B vitamins, while promoting vision health is predominantly associated with Vitamin A and related compounds. Additionally, while several B vitamins and other nutrients play roles in energy production, Vitamin K is not involved in that process. Thus, understanding the specific functions of vitamins helps clarify their importance in maintaining various physiological processes within the body.
