Resveratrol, a phytonutrient found in grapes and red wine, has tremendous potential to support a healthy lifespan.* However, since resveratrol has a short half-life, so it doesn’t stay in the bloodstream long — making it hard to reap its full potential. Resveratrol-SR™ features MicroActive® Resveratrol Complex, which releases resveratrol over 12 hours and has 2.5x better bioavailability than regular resveratrol.
