With USANA’s unique formulation, Proflavanol C100 bioflavonoid supplement combines the highest quality grape-seed extract with the free-radical quenching power of vitamin C, giving you an important tool in the quest for lifelong good health. Laboratory studies done at USANA confirm that, when used together, these ingredients provide significantly better protection against the oxidative modification of low density lipoproteins (LDL) than would be predicted from the sum of their individual effects.
