Vitamins Understood: Vitamin D

Posted in February 19, 2011

How do you get your daily dose of vitamin D? Most people primarily get vitamin D from the sun’s ultraviolet light ; however this is not the only way you can gain this essential vitamin. But what is vitamin D, and what does your body use it for?
What is it?
Vitamin D is a fat-soluble vitamin which is important for many of the body’s functions. It contributes to the normal function of the immune system and cell division; however vitamin D is perhaps better known for working with calcium in your body to maintain bone health.
Vitamin D sources
There are a number of different sources for the intake of vitamin D. Some of the dietary sources include:
  • Cod liver oil
  • Fatty fish (salmon, mackerel, tuna, sardines, herring)
  • Nuts (almonds, hazelnuts, walnuts)
  • Milk and cereal (fortified with vitamin D)
  • Eggs
  • Some of the other sources of vitamin D consist of:
  • Ultraviolet rays (sunshine)
  • Multivitamins
  • Vitamin D capsules, tablets, and liquids
What is it used for?
As previously mentioned, vitamin D is used for a number of important functions in the body. In fact, having the proper amount of vitamin D may help to support a number of health conditions:
  • Post-menopausal women who are at a higher risk of osteoporosis can take vitamin D with calcium supplements to help with prevention, as well as helping to reduce the rate of bone loss.
  • Vitamin D may reduce the risk of falling. In seniors, the vitamin may reduce falls by 22%.
  • People with disorders of the parathyroid gland are often treated with vitamin D. The glands produce parathyroid hormone (PTH) which helps the body use and store calcium.
  • Those who have lower levels of vitamin D are more likely to suffer obesity (than those with lower levels of vitamin D); however one study showed that people who were not getting enough calcium to start with saw the most benefit of weight difference.
