Benefits of Vitamin D
Research shows that many types of cancer cells have places on them for the active form of vitamin D to bind. When vitamin D binds there, replication of the cancer cells slows down. But because excess vitamin D is very toxic, it's difficult to use vitamin D therapeutically to treat cancer, except in research settings.
However, having some sun exposure daily to keep vitamin D levels up has been shown to reduce the risk for colon cancer. Just don't overdo the tanning -- skin cancer is strongly associated with sunburn!

Vitamin D regulates whether minerals are deposited into bones or withdrawn
from them, preventing soft or weak bones.
Vitamin D may also play a role in protecting people from multiple sclerosis. This disease is so much more common in northern climates that researchers are studying whether vitamin D deficiency increases the risk for developing this disease.
Topically applied, vitamin D may be helpful for psoriasis by limiting the growth of abnormal skin cells. Topical vitamin D for psoriasis is available only by prescription and can be quite expensive.
Other uses for vitamin D include reducing the symptoms of some forms of arthritis and maybe even helping to reduce the risk for insulin-dependent diabetes in young children.
If you're not getting enough vitamin D daily, you can increase your intake through taking supplements. In the next section, we'll discuss what types of supplements exist and how to know if you need to up your vitamin D dosage.
While sunlight is one way to obtain vitamin D, it's not the only way. Many foods contain vitamin D -- some, such as milk, have even been fortified with it. In the next section, we'll learn which foods are the best sources of vitamin D.
