Which vitamin is important for tissue building and healing?

Vitamin C plays a critical role in tissue building and healing due to its essential function in collagen synthesis. Collagen is a key protein that provides structure and strength to various tissues, including skin, tendons, ligaments, and blood vessels. It is also involved in the repair and regeneration of tissues following injury. Furthermore, vitamin C acts as an antioxidant, helping to protect the body from oxidative stress, which can interfere with the healing process.

Additionally, vitamin C supports the immune system, enabling the body to respond more effectively to injuries and infections, which is vital during the healing phase. The presence of vitamin C is necessary for the functionality of enzymes involved in the formation of collagen and other vital compounds needed for repair. This is why it is particularly highlighted in the context of tissue building and healing, making it the correct answer in this scenario.
