However, as researchers look harder, they are discovering many more antioxidants. This may be because they have not been known for so long, or because the FDA has not given them official sanction.
Enzyme antioxidants are the body's first line of defense against free radicals.
Our bodies produce them to combat free radicals. SOD helps prevent damage that is implicated in tissue degeneration associated with aging. Unfortunately, studies show that SOD's natural production tapers off as we age. It all starts with oxygen. These free radicals are of minimum concern if kept at reasonable levels our bodies produce enzymes to combat them, and free radicals are helpful in some body processes.
