Vitamin D is often called the “sunshine” vitamin and is produced by the interaction of sunlight on the skin. Vitamin D is a fat-soluble vitamin and not only supports immune system health but is also needed for healthy bones and teeth. When sun exposure is limited, vitamin D levels may not be adequate. Zinc supports several aspects of immune health. It ensures the normal development and function of immune cells and by supporting the skin barrier. The skin protects against foreign invaders entering the body.
