      What happens when the best minds get together to produce a red grape cell powder?

      KEZORN's combination of Piceid Resveratrol and other polyphenols from the red grape is scientifically proven to have optimal absorption and bioavailability resulting in vasodilatation of blood vessels.

      The Piceid Resveratrol combined with the full bouquet of polyphenols from grape powder, derived through this novel bio-farming process, is far superior to the normal trans-Resveratrol supplements which are solvent-derived from Polygonum. This makes KEZORN simply not comparable to a standard Resveratrol supplement.
