What is Grape Seed Extract?


Grape seed extract is extracted from natural grape seeds with effective nutrients and active ingredients, refined from nutritious food vitamin E and other main raw materials. A human grape seed extract is a new type of high-efficiency natural antioxidant substance that cannot be synthesized from the grape seed body.


Procyanidins are rich in oligomeric proanthocyanidin complex (OPC), which is a powerful antioxidant. In addition to its super-rich efficacy that is more than 20 times higher than vitamin C, it is also 50 times stronger than vitamin E. It helps to strengthen the immune system, can also delay the aging process, and has a high market value. Proanthocyanidin B2 is the most active compound that neutralizes free radicals that cause aging, and is only available in grape seeds. In Europe, OPC in grape seed proanthocyanidin extract has been adopted and used for decades as a safe and effective compound. It has no records of acute or chronic toxicity, and there are no harmful reactions even at very high doses. For these reasons, grape seed proanthocyanidin extract has become a new star in the food supplement market.
