Summary

High blood sugar (glucose) levels are associated with diabetes and prediabetes. Prediabetes is when blood sugar is high, but not high enough to be classified as diabetes. This study, conducted by two Indian research departments, evaluated the effect of 12 months of vitamin D supplementation on glucose levels and the progression of prediabetes to diabetes. 137 subjects received either additional vitamin D (69 subjects) or no vitamin D (68 subjects). Fasting glucose levels, glucose levels 2 hours after consumption of glucose (2-h glucose levels), and long-term glucose levels were estimated in blood at the beginning of the study and after 6 and 12 months. The results showed significantly lower fasting glucose levels, 2-h glucose levels, and long-term glucose levels in the vitamin D group compared with the group that did not receive vitamin D. This means that vitamin D supplementation significantly lowered glucose parameters in people with prediabetes. Further details can be found in the study.
