Vitamin d pills tested to fight diabetes inflammation
NCT ID NCT06993064
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether taking 4000 IU of vitamin D daily for six months can reduce inflammation in Mexican adults with type 2 diabetes. Researchers will measure blood markers like glucose, insulin, and C-reactive protein in 40 participants. The goal is to see if vitamin D can help control the chronic inflammation linked to diabetes complications.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Vitamin D3 (4000 IU daily)
- What this could lead to
- If it works, this could show that vitamin D helps reduce inflammation in people with type 2 diabetes, potentially improving disease control.
- What could go wrong
- This is a small, early-stage study with only 40 participants, so results may not apply broadly. It also cannot prove that vitamin D directly improves diabetes outcomes.
