Vitamin D supplements may reduce risk of type 2 diabetes, researchers say

BOSTON - Vitamin D supplements may reduce the risk of type 2 diabetes in some people.

Researchers at Tufts Medical Center reviewed three previous studies and found that among adults with prediabetes, or slightly elevated blood sugar, those taking vitamin D supplements reduced their risk of progressing to type 2 diabetes by 15-percent. 

It is still not clear what dose or formulation of vitamin D provides the most benefit which needs to be studied. 

And if you wonder whether you should be taking vitamin D supplements, consult your primary care provider.
