Grape seed extract consists of a complex mixture of flavonoids, vitamin E, zinc, copper, selenium, linoleic acid and phenolic procyanidins. The active agents of the extract are, for the most part, polyphenols or OPC (oligomeric procyanidins). Proanthocyanins and catechins are potent antioxidants with 20 times more powerful vitamin E and 50 times more potent than vitamin C.

Grape seed extract has an incredible antioxidant power

Grape seed extract has an incredible antioxidant potential due to phytonutrients. These include polyphenols, resveratrol and unique complexes called oligomeric proanthocyanins (OPC). The strongest form is in grape seed extract because it contains 95% OPC, which is higher than any other antioxidant extract.

OPC helps the body produce glutathione, a master antioxidant that protects DNA and strengthens the immune system. It also increases vitamin C intracellularly and capillary consolidation and thus improves blood oxygen circulation throughout the body. These antioxidants also act to protect the collagen of soft tissues in the joints and the skin from free radicals and premature aging.

Strong effects against the free radicals of grape seed extract protect the skin from UV radiation, walls of blood vessels of stress and inflammation, and the brain of a small oxygen status. Due to the benefits of grape seed extract on these systems, it has been observed that these seeds improve blood pressure, reduce skin cancer and protect against dementia.
