oPCXtra is a super antioxidant drink mix made from a combination of six major sources of bioflavonoids. Four of the sources - Grape Seed Extract, Red Wine Extract, Pine Bark Extract and Green Tea Extract - supply a group of powerful antioxidant bioflavonoids called Oligomeric Proanthocyanidins (OPC).oPCXtra is totally bioavailable, water soluble and delivered in an isotonic solution, the way nature intended it to be. This product is delivered to the small intestines within five minutes, when taken as directed.bioflavonoids are complex organic plant compounds found mostly in fruits and vegetables. They function as a cofactor or helper to the body's immune system to respond to inflammation, allergy and infection.oPC's are known to stabilize and protect collagen (a major protein in the body) from free radical damage and enzymatic digestion.oPCXtra is a super antioxidant drink mix made from a combination of six major sources of bioflavonoids.

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. 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.
