Question
In adults with prediabetes, can vitamin D supplementation decrease their likelihood of developing type 2 diabetes over several years?
Conclusion
Vitamin D supplementation, over a median of 3 years, slightly reduces the diagnoses of diabetes in older people at risk of developing type 2 diabetes (NNT = 18 – 115). The benefit is greater in patients who achieve higher serum levels of vitamin D.
