  Introduction:

• Proanthocyanidins (Oligomeric PCs): Condensed tannins with 20x the antioxidant power of vitamin E

• Malvidin-3-Glucoside: The primary anthocyanin in red grapes

• Pterostilbene: A resveratrol analog with superior bioavailability

Clinically-Demonstrated Benefits:

Reduces oxidized LDL by 40% in human trials
Extends cellular lifespan in yeast and mammalian models
