Summary
This completed study tested whether resveratrol, a natural compound found in grapes and berries, can improve blood vessel health and blood sugar control in people with type 2 diabetes. 48 adults took either a resveratrol pill or a placebo daily for 12 weeks. Researchers measured changes in artery function and blood sugar levels.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Resveratrol (a natural compound found in grapes and berries)
- What this could lead to
- If it works, this could point toward a simple, natural supplement to help manage diabetes and reduce heart disease risk.
- What could go wrong
- This is a small, early-stage trial with only 48 people. The results may not apply to everyone, and resveratrol is not a replacement for standard diabetes medications.
