A new open-label trial out of Eastern India suggests vitamin D may be able to help prevent type II diabetes in those with prediabetes.
Type 2 diabetes is a condition where you have a hard time controlling sugar in your body, and you have too much glucose in your blood. Researchers are interested if vitamin D might be able to prevent or slow the onset of type 2 diabetes, because it is involved in glucose regulation a few different ways. Vitamin D might help improve pancreatic beta cell function, and it might improve sensitivity to insulin, which helps you control how much glucose you have in your blood.
However, research to date hasn’t shown a clear role for vitamin D in the prevention or treatment of diabetes.
