Top 15 Antioxidant-Rich Pet Foods and Supplements

Antioxidants are any substances that impede oxidation in the body. That’s the literal meaning of “antioxidant,” but these molecular compounds are important because they protect cells from damage by “free radicals.” Those are atoms with odd numbers of electrons, formed when certain molecules and oxygen interact. Free radicals form a chain reaction and harm cells, but antioxidants can stop the chain reaction before damage is done. The most common antioxidants include:

  • Vitamins A, C and E
  • Alpha lipoic acid – sources include kidney and liver
  • Co-enzyme Q10 – a compound made in the body
  • Curcumin, or turmeric
  • Grape seed extract
  • Lignan – found in plant material such as flaxseed
  • Lutein – found in plant leaves and egg yolk
  • Lycopene –  a carotenoid found in tomatoes
  • Selenium –  a lack of selenium impairs antioxidant protection, but it is toxic in high doses
  • Silymarin – the active ingredient in milk thistle.

While any pet benefits from antioxidant-rich pet foods or supplements, animals suffering from chronic inflammation are in greatest need. That includes dogs or cats exhibiting arthritis symptoms, combating skin ailments, or fighting immune disorders. Quality foods filled with antioxidants can help delay age-related cognitive impairment in canines and felines and improve eyesight.

Always consult your animal care provider before giving your pet supplements. Even though antioxidants are generally safe, there is always a possibility of over-supplementation and possible toxicity, depending on the animal’s diet or overall health. Pregnant or lactating animals should not receive certain supplements, nor should pets undergoing chemotherapy or other cancer treatments. Always tell your animal care provider if your pet experiences any side effects from a supplement, and discontinue the supplementation until the animal has an examination.
