Grape (Vitis vinifera) Seed Extract is a Botanical supplement available in 1 form.

Not all forms of Grape (Vitis vinifera) Seed Extract are equal. The form you choose determines how much Grape (Vitis vinifera) Seed Extract actually reaches your tissues, and the difference between the best and worst forms can be substantial. Grape seed extract standardized for oligomeric proanthocyanidins (OPCs) provides some of the most potent plant-derived antioxidant compounds with high bioavailability and blood-brain barrier permeability. Research supports OPC-standardized grape seed extract for promoting healthy vascular function, collagen integrity, and antioxidant protection.

Grape Seed Extract Preferred (Preferred Form) has a bioavailability rating of good absorption.

Grape seed extract provides concentrated oligomeric proanthocyanidins (OPCs) — among the most potent naturally occurring antioxidants. Research demonstrates support for endothelial function, blood pressure management, and collagen cross-linking protection. OPCs have 20x greater antioxidant capacity than vitamin C and 50x greater than vitamin E in vitro.
