Vitamin supplements offer antioxidants such as vitamin E, vitamin C, and vitamin A. These antioxidants combat reactive oxygen intermediates (free radicals). In order for us to understand why it is important to take a vitamin supplement rich in antioxidants, we need to understand free radicals.

A free radical is simply a molecule that is missing an electron. As soon as a molecule loses one of its attached electrons, it becomes unstable and seeks to re-stabilize itself by stealing an electron from the nearest molecule. This causes the attacked molecule to then become a free radical, and starts a chain reaction. Ultimately as the process continues this can lead to cell damage.

In light of the role free radicals play in the onset of aging and disease, it is important to ensure our diets include a rich and diverse supply of antioxidants to improve the health of our cells throughout our bodies and to protect our cells from the ravages of oxidation.

The cells of our bodies are now increasingly subject to damage from free radicals due to the high levels of environmental toxins in our diet and the reduced levels of antioxidants in our food to combat free radical damage. Most companies which make skin care related products tout the goodness of antioxidants and natural products that contain antioxidants.

We are exposed to huge amounts of free radicals from pollution, and pesticides. Every time you breathe, you take in millions of free radical molecules created by cigarette smoke, radiation, and automobile emissions. Every time you eat, you consume free radicals in the form of pesticides and preservatives.

An antioxidant is a chemical that reduces the amount of oxidation in your body. They are also the cells that are stored in your muscles to help contain the damage that can occur with oxidation. Oxidative stress is being shown to be at the root of disease and aging.

As we age, free radical levels rise and yet the body falls short in producing necessary amounts of antioxidants to meet this challenge. Today, a great deal of experimental evidence supports the premise that length of life is determined by the crucial balance of antioxidants with free radicals in the body. If you find it difficult to consume an abundance of antioxidants from the recommended food groups, then taking daily supplements should solve the problem.

Pollution, alcohol, drugs, radiation from television, computers and hand phones, chemicals, cigarette smoke and stress generate free radicals in our bodies. Unstable and highly reactive, these free radicals attack your cell membranes. They then stimulate biological reactions that have been connected to accelerated cellular aging. Free radicals are highly unstable molecules that are naturally formed inside our bodies by the process of oxidation. They are normal by products of everyday functions like digestion and physical activity.

The production of free radicals is a normal bodily process, and it is part of the process of breathing and living. Free radicals are normally neutralized by the body's natural defense system, rendering them harmless. However, anything that weakens the body's natural defenses weakens its ability to fight off these free radicals. Those weakening agents include environmental pollution, excess UV radiation and even excessive consumption of alcohol.
