There are 86 million Americans with pre-diabetes (1/3 of the adult population) and their chance of developing diabetes is about 10% per year. Lifestyle changes, such as healthy eating and exercising, aiming at weight loss can lower risk of diabetes. However, many people at risk still develop diabetes despite efforts at changing lifestyle.

Know someone, a friend or family member, who may be at risk for developing diabetes and might be interested in joining D2d as a participant and contribute to diabetes research? You can easily share with others by email or on social media.
The D2d study aims to definitively answer that question: "Can vitamin D reduce the risk of developing type 2 diabetes?” says Myrlene Staten, M.D., D2d Project Officer at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), part of NIH. “Vitamin D use has risen sharply in the U.S. in the last 15 years, since it has been suggested as a remedy for a variety of conditions, including prevention of type 2 diabetes. But we need rigorous testing to determine if vitamin D will help prevent diabetes. That’s what D2d will do."
D2d is a large-scale clinical trial to investigate if vitamin D supplementation helps prevent or delay type 2 diabetes in adults who are at high risk for diabetes (pre-diabetes). "Past observational studies have suggested that higher levels of vitamin D may be beneficial in preventing type 2 diabetes, but until the D2d study is complete, we won’t know if taking vitamin D supplements lowers the risk of diabetes,” said Anastassios G. Pittas, M.S., M.D., the study’s principal investigator. The D2d study is funded by the National Institutes of Health and taking place in 22 cities across the United States.
D2d takes place in 22 medical centers across the United States. Approximately 35% of the US population lives within the larger metropolitan areas covered by the D2d sites. In Los Angeles, there is a D2d site at the Keck School of Medicine at the University of Southern California led by Dr. Peters. The LA D2d team looks forward to contributing to the knowledge to help people with pre-diabetes.
Michael Bloukas was diagnosed with pre-diabetes in 2010 and was told by his primary care doctor that he needed to take measures to reduce his risk for type 2 diabetes. He lost a considerable amount of weight, studied up on diabetes, and changed his lifestyle, which improved his elevated blood glucose levels. Bloukas’s doctor took notice of the progress and suggested he join the D2d trial. He didn’t have to think too hard about enrolling. He agrees that the experience has been positive. “I was pleasantly surprised by the research that is done and the people in the program, he says. “So far it has been a very good experience, and I appreciate the people that I deal with.”
