Benefits of Cod Liver Oil for Dogs

Is your dog experiencing bouts of pain and inflammation? There is a simple way to help fight against these conditions using a natural, holistic approach - Cod Liver Oil. 

Keep reading to learn more about the many benefits of Cod Liver Oil and the easy ways you can start implementing this fishy supplement into your dog’s daily routine.

What is Cod Liver Oil? 

Cod is a type of fish typically found in the Northern Atlantic Ocean and also in the Pacific Ocean. Not only can Codfish be eaten by dogs and humans (for instance, crunchy, dehydrated dog treats can be made from the skin), but the fish oil extracted from the livers of Codfish is also used as a dietary supplement for dogs and humans alike. Cod liver oil has a high Omega-3 fatty acid content, which includes eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) [2, 3, 10]. 

Atlantic Cod (Gadus morhua), and other species from the Gadidae fish family, are generally the main sources of Cod Liver Oils. Humans have a long history with Codfish, too - in the 18th, 19th, and early 20th centuries, Cod Liver Oil was used to treat rickets, a disease characterized by defective bone growth that is caused by a lack of vitamin D [2, 3, 10].

Why Choose Cod Liver Oil for Your Pup? 

Cod Liver Oil is good for dogs, especially dogs suffering from inflammatory conditions like pancreatitis, IBD, hepatitis, dermatitis, and inflammatory brain disease, or aging dogs who need joint support for arthritis or other joint issues. 

Just one teaspoon of Cod Liver Oil contains: 

- Omega-3 fatty acids: 890 mg
- Vitamin A
- Vitamin D

      Not to mention, 0 mg of Sodium and 0 g of total carbohydrates. 

      Cod Liver Oil has been shown to support doggy cardiovascular and brain health, and even act as an anti-inflammatory for dogs with arthritis [3]. Studies done on the use of fatty acids in fish oil for dogs have included those involving:

      - Inflammatory Skin Disorders
      - Cardiovascular Disorders
      - Renal Disease
      - Osteoarthritis and Joint Health
      - Hyperlipidemia
      - Cognitive Function Disorders
      - Cancer
      - Lipid and Metabolic Disorders

          What else is going on in Cod Liver Oil you ask? Let’s take a look: 

          - Vitamin E: Vitamin E is a group of eight fat-soluble compounds with powerful antioxidant effects, like protection from oxidative damage by neutralizing free radicals, and support for a strong immune system, a healthy gut, and healthy eyes and skin [5, 6].
          - Vitamin A: Vitamin A has been shown to help maintain healthy vision and promote immunity support. Vitamin A contains beneficial compounds like retinol, retinal, and retinoic acid. A dog’s skin, coat, muscles, and nerves all require vitamin A for proper optimal function [7].
          - Vitamin D: Also known as Cholecalciferol, vitamin D3 aids calcium absorption into the blood and has been shown to help maintain healthy bones. For the canine body, vitamin D is an essential key nutrient that helps regulate healthy muscle and nerve functions, plus a healthy skeletal system [8, 9].

              Why Are EPAs and DHAs So Good for Your Pup? 

              These healthy fatty acids are long-chain Omega-3s and are considered the “offspring” of Alpha Lipoic Acid (ALA), which is associated with a wide range of health benefits like decreasing whole-body inflammation, supporting eye and brain development, and promoting healthy digestion, absorption, and the creation of energy [1, 4]. Omega-3 and even vitamins like B12 can be easily found in supplements containing fish oil, such as Cod Liver Oil [2]. 

              How Can I Give My Dog Cod Liver Oil?
