When It Comes to Good Health, Vitamin D Delivers

Ignored for years, today vitamin D is a superstar. Here`s what you need to know about this vitally important nutrient, including how to make certain you`re getting enough vitamin D to protect your health.

According to conventional wisdom, we should be wary of anything that sounds too good to be true. But vitamin D is shaping up as an exception to that rule. Although it was discovered nearly 100 years ago, vitamin D was long believed to have only one important role, maintaining healthy bones. As a result, it was added to milk in the 1930s, as a way to combat the high incidence of rickets in children and then pretty much forgotten.

How things change! During the past decade, a steady stream of news from researchers all over the world is proving that vitamin D helps protect us against such serious health concerns as cardiovascular disease, autoimmune disorders, several types of cancer (including breast, colon and prostate), diabetes, emotional difficulties, such as depression and bipolar disorder, muscle function and gum health.
Vitamin D supports better brain function in older individuals, according to the findings of a recent clinical trial. Researchers at Tufts University found the best cognitive test scores among subjects with high blood levels of the nutrient. Those with high levels of vitamin D were better at "executive functions," such as organizing, planning and thinking in the abstract.
