Canine Antioxidant Formulas

Canine antioxidant formulas are beneficial for your pet as antioxidants neutralize free radicals and prevent them from reacting with other cells in your pet’s body. Antioxidants are chemical compounds such as vitamins or enzymes that prevent free radicals from reacting with other cells.

Free Radicals

Free radicals are produced during bodily processes and also due to pollutants such as tobacco smoke, x-rays and food additives or preservatives. They are molecules that have a missing electron and combine with molecules of other cells in a process called oxidation. Free radicals and oxidation can damage cells resulting in disease and aging.

  • Green leafy vegetables
  • Broccoli
  • Beet
  • Peas
  • Beans
  • Carrots 
  • Whole grains

Are Antioxidant Supplements Necessary for Dogs?

Dogs are generally given commercial dog food that contains preservatives and additives. The products have less vegetables and fruits. In addition, they are exposed to a lot of pollutants such as cigarette smoke, pesticides and insecticides. Therefore, all dogs benefit from the administration of antioxidant supplements.

These supplements are essential for dogs suffering from diseases such as:

  • arthritis
  • skin allergies
  • eye problems
  • heart disease
  • cancer
  • asthma
  • autoimmune disorders

Antioxidants are also beneficial to dogs that show signs of nervousness, stress or anxiety.

  • grape seed extract
  • alpha lipoic acid
