What essential vitamin is important for immune function and skin health?

Vitamin C is crucial for immune function and skin health due to its role as a powerful antioxidant. It helps protect cells from damage caused by free radicals and supports the immune system by enhancing the production and function of white blood cells, which are vital for combating infections.

Additionally, Vitamin C is important in the synthesis of collagen, a protein essential for maintaining healthy skin, blood vessels, and connective tissues. Collagen gives skin its structure and elasticity, contributing to the healing of wounds and overall skin integrity. Thus, adequate levels of Vitamin C can lead to improved skin health and a stronger immune response, making it an essential nutrient for these functions.
