The final common pathway of kidney damage in chronic renal failure involved inflammation and fibrosis. Many studies support the role of omega 3 DHA to slow the progression of chronic kidney disease in different species. The mode of action of omega-3 is summarized on the figure below:
The most beneficial omega-3 is generally thought to be docosahexaenoic acid (DHA). DHA is principally found in oily fish like salmon or tuna and microalgae from the phytoplankton. Fish obtain DHA from consuming algae. As there is an increasing concern about overfishing and its impact on biodiversity in the oceans, algae-derived DHA is a preferable and sustainable alternative source for our companion animals and their guardians. Depending on the severity of chronic renal failure we recommend a dose of 8 or 20 mg DHA per kg of body weight daily for the life of the cat.
Think your older cat is getting enough Omega-3 from their food? You might want to reconsider. The processing of commercial pet food actually renders DHA and EPA inactive, therefore no matter what you’re feeding your pet, unless you’re supplementing Omega-3 fatty acids daily, your companion probably is not getting the amount needed.
