Which vitamin is primarily involved in blood clotting?

  1. Vitamin A

  2. Vitamin D

  3. Vitamin K

  4. Vitamin E

The correct answer is: Vitamin A

Vitamin K plays a crucial role in the process of blood clotting. It is essential for the synthesis of certain proteins known as clotting factors, which are necessary for the blood coagulation process. Without sufficient vitamin K, the body cannot produce these proteins effectively, leading to an increased risk of excessive bleeding. Other vitamins, such as Vitamin A, Vitamin D, and Vitamin E, serve important functions in the body, like supporting vision, enhancing calcium absorption, and acting as antioxidants, respectively. However, they do not directly influence blood clotting in the same way that vitamin K does.
