Which vitamin is crucial for normal blood clotting and injury response?

Vitamin K plays a vital role in the process of blood clotting and is essential for proper injury response in the body. It is involved in the synthesis of proteins that mediate blood coagulation, which is necessary to prevent excessive bleeding when injuries occur. Without adequate Vitamin K, the body cannot effectively produce these clotting factors, leading to an increased risk of uncontrolled bleeding.

In contrast, while Vitamin A is important for vision and immune function, Vitamin C is primarily known for its role in collagen synthesis and immune support. Vitamin D is crucial for calcium regulation and bone health, but it does not have a direct role in blood clotting. Thus, Vitamin K stands out as the only vitamin directly associated with the blood coagulation process.
