Vitamin D is an essential nutrient for the human body. This fat soluble vitamin is one of the most unique vitamins that are used by the body because the skin actually produces it through sunlight.
It is the only vitamin that helps the body absorb calcium and phosphorus which are vital for bone health. Apart from this, vitamin D controls cancer growth, controls infection and reduces inflammation.
The recommended dietary allowance of vitamin D for adults is 15 mcg daily for both men and women. The dietary requirement for those above 70 years of age is 20 mcg daily.
