Resveratrol is a polyphenol with powerful antioxidant properties found in the highest concentrations in red wine. Resveratrol has been studied for it's ability to activate the "longevity gene" or "SIRT1" which plays a role in aging-related biological processes such as how cells react to stressors. We metabolize Resveratrol quickly which results in very low bioavailability, however Nature's Essentials uses advanced Cyclosome Liposomal technology, liposomes (good fat) to protect the Resveratrol, plus cyclodextrin, (a natural starch) to increase bioavailability so you can ABSORB MORE!
