Description
Its sometimes called the sunshine vitamin because it is produced in your skin in response to sunlight. Vitamin D is a fat-soluble vitamin in a family of compounds that include vitamins D-1, D-2, and D-3. It can affect as many as 2,000 genes in your body. Your body produces vitamin D naturally when its directly exposed to sunlight. Besides getting vitamin D through sunlight, you can also get it through certain foods and supplements to ensure adequate levels of the vitamin in your blood. Vitamin D has several important functions. Perhaps the most vital are regulating the absorption of calcium and phosphorous, and facilitating normal immune system function. Getting a sufficient amount of vitamin D is important for normal growth and development of bones and teeth, as well as improved resistance against certain diseases. If your body doesnt get enough vitamin D, youre at risk of developing bone abnormalities such as soft bones (osteomalacia) or fragile bones (osteoporosis).
