No effect of resveratrol supplementation after 6 months on insulin sensitivity in overweight adults: a randomized trial.

Background: Effects of resveratrol on metabolic health have been studied in several short-term human clinical trials, with conflicting results. Next to dose, the duration of the clinical trials may explain the lack of effect in some studies, but long-term studies are still limited.

Objectives: The objective of this study was to investigate the effects of 6-mo resveratrol supplementation on metabolic health outcome parameters.
