Resveratrol and Type 2 Diabetes
- Conditions
- Type 2 Diabetes
- Interventions
- Dietary Supplement: placeboDietary Supplement: resveratrol
- Registration Number
- NCT01638780
- Lead Sponsor
- Maastricht University Medical Center
- Brief Summary
The main objective of the study is to investigate if resveratrol supplementation can improve overall and muscle-specific insulin sensitivity in type 2 diabetic patients.
As a secondary objective the investigators want to investigate whether the improved insulin sensitivity can be attributed to improved muscle mitochondrial oxidative capacity and a reduced intrahepatic and cardiac lipid content.

- Arm && Interventions
Group Intervention Description placebo placebo A placebo will be given for 30 days, twice daily. One pill will be provided with lunch and the other pill will be provided with dinner. resveratrol resveratrol resveratrol will be given for 30 days, twice daily. One pill, which contains 75 mg of resveratrol, will be provided with lunch, and the other pill of 75 mg will be provided with dinner. So in total 150 mg/day of resveratrol will be given.
