Which vitamin is linked to immune system and healthy skin?

• A. Vitamin A
• B. Vitamin D
• C. Vitamin C
• D. Vitamin E

Answer: (D)

Understanding how vitamins support both immunity and skin health helps here. Vitamin E is a fat-soluble antioxidant that protects cell membranes, including skin cells, from oxidative damage. This helps maintain a healthy skin barrier and resilience against irritation or injury. It also supports the immune system by keeping immune cell membranes stable and modulating inflammatory responses, which can enhance how well the body responds to pathogens. While other vitamins contribute to immunity or skin health in their own ways, Vitamin E’s antioxidant protection of skin cells and its role in supporting immune cell function make it the one linked to both immune health and healthy skin.
