Reserveage Resveratrol supplements are created through combining standardized amounts of resveratrol from Japanese knotweed with our polyphenol blend from our patent-pending, proprietary process called Vine to Capsule® technology that preserves the essential phytonutrients found in grape skin, vines and stems. By partnering with a state-of-the art polyphenol manufacturing facility just minutes from the vineyards where we source the ingredients in our premium Pro-Longevity Factors® Blend, we are able to boost its bioavailability, resulting in products dedicated to purity, potency and freshness.
