Grape seed extract is made up of grape seed extract polyphenols, main ingredients are Oligomeric Proantho Cyanidin(OPC), it is extracted from grape seeds of a human body cannot synthesize a new type of high efficient natural antioxidant, which has been found that the plant source of one of the most effective antioxidant in vivo and in vitro experiments show that the antioxidant effect of grape seed extract, 50 times stronger than vitamin E, 20 times stronger than vitamin C, it is effective at scavenge excess free radicals in the body.
Used in food supplements, health food and cosmetics. It has super effects of delaying aging and strengthening immunity. The main known effects include anti-inflammation, anti-histamine, anti-allergy, anti-allergens, anti-oxidation, anti-fatigue, strengthening physique, improving sub-health state, delaying aging, improving irritability, dizziness, fatigue, memory loss symptoms, beauty, promoting blood circulation, etc.
