NCT ID NCT07541729
First seen Jun 25, 2026 · Last updated Aug 27, 2026 · Updated 3 times
Summary
This early-stage trial is testing whether a rosemary extract supplement can improve markers of oxidative stress and inflammation in people with type 2 diabetes. Forty adults with stable diabetes will take either the extract or a placebo for 12 weeks. The study focuses on blood biomarkers, not direct health outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- rosemary extract
- What this could lead to
- If it works, this could point toward a natural supplement to help manage oxidative stress and inflammation in type 2 diabetes.
- What could go wrong
- This is a very early phase 1 trial with only 40 people, so results may not be conclusive. It's testing biomarkers, not clinical outcomes, so even positive results may not translate to real-world benefits.
