Which vitamin is vital for wound healing?

Vitamin C plays a crucial role in wound healing due to its involvement in collagen synthesis, which is fundamental for the structural integrity of healing tissues. Collagen is a protein that provides strength and support to various tissues, including skin and blood vessels. Vitamin C assists in the formation of new connective tissue, facilitates the function of white blood cells in the immune response, and aids in the absorption of iron, which is vital for oxygen transport in the body. These functions collectively enhance the body's ability to repair and regenerate tissues following injury or surgery, making Vitamin C an essential nutrient for effective wound healing.

In contrast, while Vitamin A supports skin health and immune function, and Vitamin D is important for bone health and the immune system, neither plays as direct a role in collagen formation as Vitamin C. Vitamin B12, primarily associated with nerve function and the production of red blood cells, does not have a direct influence on the wound healing process compared to the significant impact that Vitamin C has.
