How do antioxidants work?

By Haiyan Lai-Heskin

Small wonder that supplements containing antioxidants to slow, stop or reverse the effects of aging enjoy great success in the marketplace.

Vitamins that have been particularly noted for their antioxidant properties include Vitamins A, C, and E. Aside from the fact that these are a wound to the pocket, antioxidant products offer a delight to those who would like to look young in a flash. But how does this free-radical sponge really work?

Free radicals are produced naturally in your body and are perfectly safe if they stay below a certain level. They are known as "reactive oxygen species", or ROS and first identified by Moses Gomberg in 1900. Free radical creation is part of living and as the cells produce energy (for function and survival), the also create oxygen molecules that are unstable because its electrons are unpaired.

Free radicals are highly reactive as they try to steal electrons from other molecules, including DNA and cellular membranes. Drinking, the radiation coming from TVs and computers, drugs, and cigarette smoking spawn free radicals.

The best recipe for stopping the formation of free radicals and reducing the production of more of them is to have enough sleep(at least seven hours a day) and stay active, exercise and live right.

Free radicals cause damange to healthy cells and are associated with signs of premature aging, they hurt the body by initiating chain reactions of electron scavenging that damage the body's cells. All these damages would mount up and cause our body to accelerate aging.

Free radical are detrimental to our body,as the same logic that oxidation damages metals. Upon breathing, oxygen induces a process called oxidation. And it is in here where free radicals form. This process is likened to the oxidation of metals. Once oxidized, aluminum turns to be white, iron becomes rusty, and copper transforms into green.

Antioxidants help to solve the problems listed above by mopping up the free radicals in the system, and having extra electrons that they are willing to give up to the free radicals, but the antioxidants do not become free radicals themselves in doing so.

Antioxidants work by significantly slowing or preventing the oxidative or damage from oxygen process caused by free radicals that can lead to cell dysfunction and the onset of problems like heart disease and diabetes.

Antioxidants are the knights in shining armour that subjugate the attack of free radicals in the body, the hazardous molecules that damage cells and procure aging and disease. They prevent glaucoma and the age-related degeneration of our macula, and fight the effects of free radical damage by boosting the skins natural protection.

As we get older, Glutathione - is said to be the most powerful antioxidants as are naturally present in our body since we were young is depleted. Supplements like Vitamin A, E, C and selenium, are known to be powerful antioxidants, plays an essential role in the synthesis of collagen.

If antioxidant supplements are not your type, you may take some delectable bite of the super fruits such as blueberry and raspberry which are said to contain the most number of antioxidants.

As you have the current understanding of antioxidants as reducing agents that break oxidative chain reactions, often by scavenging reactive oxygen species before they can cause damage to the cells, no wonder those magic tablets in such high demanding. - 17268
