What are free radicals?
All living matter is composed entirely of molecules, which are made up of atoms and electrons. Ordinarily, electrons occur in balanced pairs and keep atoms and molecules stable. Sometimes, however, a molecule loses one of its electrons and therefore becomes unbalanced and highly reactive. The unstable molecule is known as a "Free Radical". Free radicals damage healthy cells and in turn impair the body's normal functions.

Free radicals are produced from:
Normal respiration and metabolism
Exposure to air pollutants
Sun
Radiation from X-rays
Drugs
Viruses
Bacteria
Parasites
Dietary fats
Stress
Injury

How do free radicals affect the body?
Free radicals are known today to be one of the most destructive forces in the body of an aging animal. This is especially true when talking about your pet's joints and other tissues. Free radicals cause a loss of cellular flexibility and strength, and can cause joints and cartilage to become stiff, cloud vision, cause arteries to lose their elasticity, inflammation, and gastrointestinal and liver disorders.

Research has shown that free radicals are involved in many age-related conditions such as:
Arthritis
Cancer
Kidney and liver disorders
Vascular disorders
Weakened immune system
