Vitamin D & Type 2 Diabetes: D2d Study

Irwin Brodsky, MD Maine Medical CenterUnder the direction of Dr. Irwin Brodsky, site Principal Investigator, MMC has joined a group of twenty sites around the country in this large multi-center clinical trial.  This trial aims to determine whether vitamin D supplementation is safe and effective in delaying the onset of type 2 diabetes in people at risk for the disease and to gain a better understanding of how vitamin D affects glucose metabolism.

The D2d study will enroll approximately 2,400 participants nationwide who are at risk of developing type 2 diabetes; the enrollment goal at Maine Medical Center is 125 participants. Participants are randomly assigned to receive either vitamin D or placebo and be followed for up to 4 years for development of diabetes. The study is expected to define the role of vitamin D supplementation in modifying diabetes risk in people at risk for the disease.
