Vitamin D is a fat-soluble steroid vitamin that helps the body absorb calcium and phosphorus. It is important for maintaining strong bones and may reduce the risk of certain cancers and autoimmune diseases. The recommended daily intake of vitamin D varies with age but is generally between 200-600 IU. Sources include sunlight, supplements, and fortified foods. A deficiency can lead to bone and muscle pain, fatigue, and increase cancer and heart disease risk. Treatment options include sunlight, supplements, or UV light therapy. Too much vitamin D can cause calcium buildup in the blood.
