Side Effects Of Fish Oil Supplements For Pets

  • The anti-inflammatory effect of EPA and DHA increases the production of certain chemicals that alter platelet function. Platelets or thrombocytes are cells produced in the bone marrow that aid in the formation of blood clots. This is an important first line of defense to prevent blood loss from trauma or other events or conditions causing hemorrhage. The chemicals produced by EPA and DHA decrease platelet activity and aggregation to form clots. Animals fed excessive amounts of fish oil would have a tendency to suffer higher blood loss when injured or afflicted by conditions that cause bleeding. This would also be an important consideration for pets needing surgery, especially procedures on body organs or parts of the body with heavy blood flow.
  • The anti-inflammatory properties of EPA and DHA also interfere with wound healing. Inflammation at the site of a wound promotes the migration of white blood cells to the site to begin early wound healing processes. EPA and DHA decreases this necessary wound healing step and slows the bodys ability to repair the skin and promote new skin production. This is especially pronounced in the first five days of the wound healing process. Such an effect could be serious for an animal undergoing an extensive surgical procedure that was also fed high levels of dietary fish oil.

    Comparison Of Fish Oil With Flaxseed Oil

    Can Fish Oil Cause Diarrhea?

    Fish oils and fatty fish such as salmon, tuna and sardines are excellent food sources of omega-3 fats essential to brain and eye health.

    Fish fat contains the “long chain” omega-3s , which are the omega-3 fats the body needs for vital functions, including eyesight.

    In contrast, the “short chain” ALA omega-3 fat found in plant foods such as flaxseeds must be converted to EPA and DHA in the body for beneficial eye effects. When you eat plant foods, your body converts only about 5 percent of dietary ALA into essential EPA and DHA.

    Also, most Americans’ diets are too high in omega-6 fatty acids an imbalance that further reduces the amount of ALA from plant foods that gets converted to EPA and DHA. This imbalance also blunts the benefits of EPA and DHA omega-3s obtained directly from fish and fish oil.

    Omega-6 fats are found in vegetable oils used in most snacks and prepared foods whether packaged, frozen, restaurant or take-out.

    Researchers agree that most people need to reduce their consumption of these otherwise healthful omega-6 fats, which block omega-3 absorption and promote inflammation when eaten in excess.

    Fish oils, like flaxseed oil, are available in capsule and liquid forms. Some contain lemon flavoring or are processed in other ways to reduce any “fishy” taste. Cod liver oil is another good source of EPA and DHA omega-3 fatty acids.

    Popular eye supplements that contain fish oil or cod liver oil include: TheraTears Nutrition , BioTears and HydroEye .
