OPC-3™ is thought to be a free radical neutralizer or antioxidant. It is also thought to support the circulatory system and strengthen capillaries.



Antioxidants are a chemical compound or substance that are thought to prevent cellular damage. Organic substances such as vitamin E, vitamin C, or beta carotene, for example, are thought to protect cells from damage caused by unstable molecules known as free radicals.

Free radicals can form when oxygen interacts with certain molecules. Free radicals can be beneficial in neutralizing bacteria and viruses. But in excess, they produce harmful oxidation that can damage cells.

Antioxidants are molecules which can safely interact with free radicals to stop any damage to vital molecules.

Oxidation in our body through free radicals is said to be responsible for premature aging, skin wrinkles, hardening of arteries, stiff joints, cataracts, cancer and more. Due to diet, most bodies can't fight the free radicals as their is a low amount of antioxidants in the food intake.

Antioxidant supplements can be useful to counter the effect from free radicals. OPCs have been found to be non-toxic, non-antigenic, non-teratogenic, non-mutagenic, non-carcinogenic and have been used in Europe under medical supervision for over 30 years with no reports of adverse effects.

Antioxidants, such as OPC-3™, are believed to be effective in helping to prevent cancer, heart disease, and stroke. They are also thought to play a role in slowing the aging process.

Fruits and vegetables are rich in antioxidants and their are health supplements on the market such as Isotonix OPC-3™ that are marketed as antioxidants.

There are conflicting reports on the benefits of antioxidants and how much to take. So in short, supplements should not be taken to replace, a healthy, well balanced diet. It should be taken to supplement it.
