Brief Summary

The purpose of this study is to investigate the effects of the antioxidant "resveratrol" on liver fat content, body-composition and insulin sensitivity

Resveratrol is found in grape skin, wine, peanuts, and mulberries and is thought to have health benefits such as improving fat metabolism, insulin action, and possibly extending lifespan. resVida™ is the name for the dietary supplement containing the natural antioxidant "resveratrol". resVida™ will be supplied by DSM Nutritional Products, Ltd.
