Description of intervention(s) / exposure
Two arms:
1)grape skin extract 500 micrograms, three times a day, for 24 weeks; tablet
2)placebo (microcellulose) 500 micrograms, three times a day, for 24 weeks; tablet

Summary
Brief summary
In adults with metabolic syndrome the study will compare the efficacy of a grape skin extract combined with non-pharmacological treatment (diet/exercise orientation) in insulin resistance (measured using the homeostasis model assessment of insulin resistance [HOMA-IR] index), as compared to placebo plus non-pharmacological treatment (diet/exercise orientation). The hypothesis will consider the superiority of the grape skin extract therapy.
