oPC 3 contains a combination of oligomeric proanthocyanidins (OPC's) from sources that include grape seed, red wine and pine bark† extracts. The grape seed extract is the superior source of OPCs, containing 92% of active ingredients over pine bark's 84% of active OPC ingredients.The red wine extract contains flavonoids called leucocyanidins from the skin of red grapes. Leucocyanidins are bioflavonoids with powerful antioxidant properties crucial to their role in supporting the circulatory system OPC 3 also contains bilberry and citrus extracts, which are known to have effects of vision and histamine release, respectively.this powerful formula will be delivered to your system the way nature intended it to be - in an isotonic solution that maximizes absorption. OPC 3 has a pleasant natural grape flavor, is a vegetarian product, and mixes instantly when added to water. This product should be taken on an empty stomach for the fastest, most effective delivery of the active ingredient.oPC 3 contains a combination of oligomeric proanthocyanidins (OPC's) from sources that include grape seed, red wine and pine bark† extracts.

our bodies are made up of billions of molecules held together by electromagnetic forces. These chemical bonds are created with paired electrons. Free radicals are unstable molecules that have lost an electron and are unbalanced. Free radicals seek to replace the lost electron by randomly attacking nearby molecules and extracting desired electrons. One free radical can damage a million or more molecules in a chain reaction referred to as radical propagation, which leads to oxidative stress. Uncontrolled oxidation is very destructive.oPC, as it's commonly called in scientific circles, is expert at treating vascular diseases because it actually increases the structural strength of weakened blood vessels. It also has other biological activity. OPC is one of the most potent antioxidants known -- fifty times as powerful as vitamin E, according to some tests. OPC's can help neutralize the underlying chemical cause (free radicals) that promotes most diseases.when we eat food, drink a beverage, or ingest most nutritional supplements, the stomach must secrete diluting juices, enzymes, hydrochloric acid, and at least one vitamin-binding protein to begin the process of digestion. This process requires energy and time — about 40 minutes or more, depending on the size of the meal. Isotonix products are great-tasting powders that are mixed with water. They are then delivered into the small intestine nutritionally concentrated, maximizing the opportunity for absorption of nutrients across cell membranes.one can see the effects of oxidation in the rusting of metal, the rotting of meat, the browning of apples, the fading of paint, or the hardening of old rubber. Oxidation in our body by free radicals is thought to be responsible for premature aging, wrinkling of skin, hardening of arteries, stiffening of joints, formation of cataracts, and much more. We are constantly exposed to free radicals via such processes as anti-microbial activity by white blood cells, the absorption of chemical additives in our foods, and even excessive sunlight.our bodies are made up of billions of molecules held together by electromagnetic forces.
