Taking vitamin D supplements could drag 17million Americans and Brits back from brink of diabetes - Daily Mail

In a meta-analysis of 17 studies, Tufts University researchers found that pre-diabetics could reduce their likelihood of developing the potentially-crippling condition by 15 percent.

'Vitamin D in people with prediabetes was beneficial in decreasing risk for diabetes and increasing the likelihood of regression to normal glucose regulation, with no offsetting safety signals,' researchers wrote.

In an analysis published Monday in the American College of Physicians Journal, researchers from the Boston-area school found vitamin D supplements could help stave off diabetes.

Each of them also included information on patients' blood sugar as ancillary data, and the Tufts team gathered it for their major study.

Vitamin D deficiency is primarily known to be a problem during winter, when people spend even more time indoors and bundle up heavily when trekking outside.

Taking too much vitamin D can lead to calcium deposits forming in the body, harming the function of organs like the heart and kidneys.
