Rating (out of 5): 4

Fish oil supplements are widely used in veterinary medicine, particularly for dogs and cats, based on substantial scientific evidence supporting their benefits. The primary active components in fish oil are omega-3 fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Numerous studies have shown that these fatty acids have anti-inflammatory properties, which can be beneficial in managing chronic inflammatory conditions such as osteoarthritis, atopic dermatitis, and kidney disease in pets. For example, randomized controlled trials have demonstrated that dogs with osteoarthritis who received fish oil supplements showed improved mobility and reduced pain. Similarly, research in cats suggests that omega-3 supplementation can help manage chronic kidney disease by reducing inflammation and proteinuria.

In addition to their anti-inflammatory effects, fish oil supplements may support skin and coat health, reduce itching and flakiness, and promote a glossy coat. There is also evidence that omega-3 fatty acids may benefit heart health in pets with cardiovascular conditions, and emerging research points to potential neuroprotective effects, particularly in aging animals.

While most evidence is positive, dosing and purity are important considerations, as some fish oil supplements may contain contaminants or inappropriate concentrations. Overall, the use of fish oil in pets is supported by a solid body of scientific literature, especially for inflammatory, dermatologic, and renal conditions.
