Anthogenol is a naturally derived health supplement based on the proprietary isolation of OPCs (oligomeric proanthocyanidins). It has a powerful antioxidant effect (15 times greater than Vitamin C and 50 times greater than Vitamin E). Working at a cellular level, it provides protection from ravaging free radicals. The suggested dose of one capsule per day, taken before a meal, has shown benefits after three months (although you may feel benefits sooner). In some cases, such as improved endurance and varicose veins, you may need to take one capsule, two or three times daily.
