Free Radicals, Antioxidants and What to Do About Them

Every second, tens of thousands of free radicals are formed in the body. They are a natural byproduct of the processes of your cells, but they are also caused by environmental factors such as tobacco smoke and radiation.

What Are Free Radicals and What do They Do?

Free radicals are both friends and enemies of your health. Some are helpful because they kill foreign invaders and potential infections. However, this activity (phagocytosis) creates chain reactions of even more free radicals (hydrogen peroxide and hydroxyl radicals) that may cause severe tissue damage throughout the body. The reason is that they are unstable, highly reactive atoms with an unpaired (i.e. odd) number of electrons, so they are looking to steal electrons from other molecules in the body. Thus they attack cell walls, cells, artery walls and genetic material. The resulting loss of electrons from these structures is closely associated with oxidation damage (comparable to rusting). This so weakens the body's biological structures that they become unable to function properly.

Free-Radical Theory

In the 1950s, Denham Harman was first to propose the free-radical theory of aging (FRTA). Part of this theory considered the involvement of free radicals in disease. Since then, researchers have advanced more free radical theories, experiments and models. Many researchers believe that free radicals contribute to all degenerative conditions associated with aging as well as to over 60 ailments and diseases. Some hypothesize that aging itself is a free radical process. Others hold that the degenerative diseases associated with aging are a free radical process that causes aging. Regardless, it has been shown that the oxidative stress caused by free radicals can be arrested by antioxidants.

Antioxidants: The Free Radical Scavengers

Antioxidants are nutrients in foods, and enzymes in the body. They're called free radical scavengers because they can stop the damaging free radical chain reaction. But they must be replaced constantly because they become oxidants after finishing the job. So now the proper antioxidant dosage is in question. Since researchers don't know, it's very important that you don't overdose. Avoid synthetic vitamins and synthetic antioxidant formulas. Get your antioxidants from foods and from whole food (not synthetic!) supplements. This is because the body knows how to regulate antioxidant activity when the source is natural.

Krill Oil: A Powerful Whole Food Free Radical Fighter1

Krill oil is a whole food nutrient extracted from tiny shrimp-like crustaceans that are rich in astaxanthin, a super-antioxidant found in algae. Krill eat only algae, so that means the astaxanthin is esterified. This renders it 7.5 times more potent than ordinary astaxanthin, and most importantly, 100% bioavailable to your cells. No other animal gives you this form of astaxanthin.

Neptune Krill Oil (always look for the NKO trademark on any label) has an ORAC antioxidant value that's 48 times greater than fish oil and 302 times greater than Vitamins A and E. Antioxidant effectiveness against free radicals is just one of the many unique health benefits of krill oil supplements, so explore this site for the rest of the story. Then put the natural goodness of pure Antarctic krill oil to work on your health starting now!
