There is growing evidence of the role that nutrition can play in the management of veterinary patients with osteoarthritis.

Current evidence supports nutritional management of body weight and dietary fortification with the long-chain omega-3 fatty acids eicosapentaenoic acid and docosahexaenoic acid.

Additional studies suggest that supplements and diet additives such as glucosamine, chondroitin sulfate, antioxidants, and green-lipped mussel may also have some benefit in managing osteoarthritis.

Additional research evaluating pets with naturally occurring disease, using validated owner questionnaires and objective measurements, is needed.
