Vitamin D supplements reduced risk factors for type 2 diabetes by improving the function of insulin-producing cells in pre-diabetic volunteers, a new study has found. “The results...suggest that vitamin D supplementation may help to improve the main defect in type 2 diabetes,” co-author Dr. Anastassios Pittas, an endocrinologist at Tufts University Medical Center in Boston, told Reuters Health in an email. Type 2 diabetes, the most common form of the disease, affects millions of Americans. The condition is characterized by high blood-sugar levels resulting from the body’s poor response to insulin, a chemical that removes sugar from the bloodstream and stores it in the liver and muscles. Insulin is made by beta cells in the pancreas.
