Summary

This study looks at whether adding regular exercise (treadmill walking) to vitamin D supplements can improve erectile function in men with type 2 diabetes who also have low vitamin D. Forty men will take vitamin D every two weeks for 12 weeks; half will also walk three times a week. The main goal is to see if the combination works better than vitamin D alone.

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 (cholecalciferol) and treadmill walking
What this could lead to: If it works, this could point toward a simple lifestyle-plus-supplement approach to help diabetic men with erectile dysfunction and low vitamin D.
What could go wrong: This is a small, early-phase trial with only 40 participants, so results may not apply to everyone. The study also does not control for other factors that affect erectile function.
