Can Vitamin D Prevent Diabetes?

If you’re an adult with prediabetes, you could be part of a major national clinical trial at UT Southwestern that is investigating whether vitamin D helps prevent or delay development of type 2 diabetes. People with prediabetes have blood glucose levels that are higher than normal and are thus at high risk for developing type 2 diabetes. The American Diabetes Association estimates 79-million Americans have prediabetes.

"There is some evidence that treatment with vitamin D can prevent development of type 2 diabetes" says Phillip Raskin, M.D., Professor of Internal Medicine, who is leading the UT Southwestern investigation. “If that proves true, it could save people a lot of anguish and diabetes medication cost."

The Vitamin D and Type 2 Diabetes (D2d) study will examine if a daily dose of 4,000 International Units (IUs) of vitamin D in the form of D3 prevents development of diabetes. Funded by the National Institutes of Health, the multi-year D2d study is taking place at 20 sites nationwide.
