Vitamin D is essential for calcium absorption and bone health; it helps regulate immune function, among other roles. Vitamin D is naturally produced in the skin when you are outside exposed to ultraviolet light from the sun.
Foods that naturally contain vitamin D include fish (particularly salmon and tuna) shrimp, and eggs. Many foods are now fortified with vitamin D, including milk and other dairy products, to boost overall vitamin D intake. Taking a dietary supplement containing vitamin D is also a common way to maintain sufficient vitamin D levels.
