Summary

This study compares two different doses of vitamin D supplements in 108 adults with type 2 diabetes who also have low vitamin D levels. Researchers will measure changes in blood sugar and HbA1c over time to see if higher doses improve diabetes control. Participants must be aged 40-70 and taking only metformin.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Vitamin D
What this could lead to
If it works, this could show that correcting vitamin D deficiency helps control blood sugar in type 2 diabetes.
What could go wrong
This is a small, early-stage trial with no placebo group, so results may not be conclusive. Vitamin D is generally safe, but high doses can cause side effects.
