Usana was a product of a research to answer our continually eroding health. Myron Wentz, Ph.D., the company founder, and other scientists found one of the most significant research findings has been the value of antioxidants in countering the negative effect of what we call “free radicals” in the human body. Dr. Wentz felt that disease prevention was an important as detection.

What are free radicals?

Why are they damaging the human body?

Free radicals are organic molecules responsible for aging, tissue damage, and possibly some diseases. These molecules are very unstable, therefore they look to bond with other molecules, destroying their vigor and perpetuating the detrimental process.

Antioxidants, present in many foods, are molecules that prevent free radicals from harming healthy tissue. (source: wisegeek.com)

How Antioxidants May Prevent Against Free Radical Damage?

The vitamins C and E, are thought to protect the body against the destructive effects of free radicals. Antioxidants neutralize free radicals by donating one of their own electrons, ending the electron-"stealing" reaction. The antioxidant nutrients themselves don?t become free radicals by donating an electron because they are stable in either form They act as scavengers, helping to prevent cell and tissue damage that could lead to cellular damage and disease.(source:healthchecksystems.com)
