Grape seed extract packs a concentrated dose of oligomeric proanthocyanidins, or OPCs, strong antioxidants drawn from grape seeds. Manufacturers standardize the extract to guarantee a set level of OPCs, giving it a sharper profile than grape juice or wine alone.
People reach for it to help keep blood pressure and circulation on track. Others use it to support skin firmness and easy movement in the joints. The extract's antioxidant and soothing properties also make it a go to for post-exercise recovery.
Take it as a capsule or tablet with a meal so your body absorbs it well. Daily doses usually fall between 100 and 300 mg of a standardized extract, depending on the product's strength.
