Enzogenol is a natural plant extract from the bark of Pinus radiata trees consisting of polyphenols with a minimum of 80% proanthocyanidins. The Radiata pines are grown sustainably in the clean environment of New Zealand's central North Island. Only water and bark are used in the extraction of the polyphenols. There are no organic solvents or any chemicals used in the process. Enzogenol's exceptional antioxidant activity and health promoting effects have been reported in several published research studies.
