Resveratrol and Type 2 Diabetes
Effect of Resveratrol on Insulin Sensitivity and Metabolic Profile in Type 2 Diabetics

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.

  • Dietary Supplement: placebo
    A placebo will given for 30 days, twice daily. One pill will be provided with lunch, and the other pill will be provided with dinner.
  • Dietary Supplement: 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, also containing 75 mg will be given with dinner. So in total a dose of 150 mg/day will be given.
