What is Vitamin D?

Vitamin D, also known as the sunshine vitamin, is a fat-soluble vitamin that helps the body absorb calcium and maintain healthy bones. Vitamin D is produced by the body when the skin is exposed to sunlight.

It can also be obtained through dietary sources such as fatty fish, fortified foods, and supplements.

Increased risk of diabetes mellitus

How much Vitamin D do you Need?

The recommended intake of vitamin D varies by age and gender. The Institute of Medicine recommends an intake of 600-800 International Units (IU) per day, depending on age. People over the age of 70 require higher intakes of 800-1000 IU per day.
