Essential Fatty Acids for Animals

Essential fatty acids (EFA’s) play a vital role in both cell and immune function.  EFA’s are divided into two forms, omega 3 and omega 6.  Omega 3 fatty acids found in fish and other marine life decrease inflammation.  In veterinary medicine, EFA’s are often prescribed for the following animal diseases:
1) Canine cognitive dysfunction
2) Allergic dermatitis
3) Osteoarthritis
4) Chronic kidney disease
5) Heart disease to decrease weight loss
6) Cancer treatment to decrease the side effects of chemotherapy and radiation. EFA’s might also decrease tumor recurrence.

Unfortunately, essential fatty acids have unwanted side effects.  Here are a few of those side effects:
1) Has been found to inhibit insulin release in humans with type II diabetes.  Therefore, as a precaution, it should likely be used with caution in any diabetic patient including animals.
2) High doses may cause bleeding problems due to interference with platelets.  This is especially true in cats.
3) High doses of omega 6 promote inflammation and thus are not used as often in therapy.
4) Can cause vitamin E deficiency which is why patients on chronic EFA therapy should also receive vitamin E supplementation.
5) May cause recurrence of pancreatitis or diarrhea in patients with a history of these problems.
