What is vitamin D and why is it needed?

Vitamin D is one of many nutrients our bodies need to stay healthy. Among the vitamin’s main functions, it helps the body:

  • Absorb calcium. Vitamin D, along with calcium, helps build bones and keep bones strong and healthy.
  • Block the release of parathyroid hormone. This hormone reabsorbs bone tissue, which makes bones thin and brittle.

Vitamin D may also play a role in muscle function and the immune system. The immune system is your body’s defense system. It helps protect it against infections and other illnesses. Taking vitamin D every day has been shown to reduce the risk of falling in older individuals.

Other ways vitamin D is thought to help us, and how much we would need to take, is an area of active research (and controversy). There have been studies to suggest that it might help prevent colon, prostate, and breast cancers. There is also some research that it might help prevent and treat diabetes, heart disease, high blood pressure, and multiple sclerosis. However, the results of many of these studies are either preliminary or under debate. Without other long-term research, even many of the researchers who conducted these initial studies are cautious about recommending vitamin D for the prevention of these diseases.
