What Are OPCs? The Science of the Plant-Based Antioxidants in Folium pX
OPCs, or oligomeric proanthocyanidins, are a class of plant-derived bioflavonoids concentrated most heavily in grape seed and pine bark extracts, which have been studied for decades for their unique protective properties. Their molecular architecture allows them to counteract a broad range of free radicals, which makes them functionally distinct from the single-nutrient antioxidants most people […]
