Proanidin is a potent combination of two powerful bioflavonoids, Pycnogenol, extracted from Atlantic pine bark, and Proanthodyn, extracted from grape seeds. Both compounds are rich in proanthocyanidins, a special class of antioxidants that have been proven in in vitro studies to effectively scavenge both water- and lipid-soluble free radicals. In vitro studies have also demonstrated proanthocyanidins' ability to support the integrity of elastin and collagen, important constituents of connective tissue.
Pycnogenol® and Grape Seed Extract is a potent combination of two powerful bioflavonoids, Pycnogenol®, extracted from French maritime pine bark (Pinus maritimus), and Proanthodyn™, extracted from grape seeds (Vitis vinifera). Both compounds are rich in proanthocyanidins, a special class of water-soluble bioflavonoids which are excellent free-radical scavengers. Proanthocyanidins are believed to play a role in maintaining good health.
