The National Institutes of Health is funding a huge, multi-site, multi-year double-blind, placebo-controlled clinical trial to determine if vitamin D supplements may help definitively prevent or delay onset of diabetes type II in approximately 2,500 adults who are at high risk of developing the disease. The researchers’ mission is to discover if vitamin D3 (also known as cholecalciferol) is capable of preventing or delaying the development of diabetes type II in pre-diabetic adults — those with higher than normal blood glucose levels — over 30 years old. The study, dubbed “D2d” will use a dose of 4,000 IU, and the investigators are hopeful for a solid outcome, based on earlier studies investigating the role of vitamin D and diabetes risk reduction.
Currently, approximately 80 million Americans are living with higher than normal blood glucose levels, and about 26 million have diabetes. Depending upon the outcome of this significant study, vitamin D may have a grand new role to play.
