Not all supplements are equal. Here's what the active ingredients actually do — and what the research says.
Contains a unique combination of omega-3 fatty acids and glycosaminoglycans not found elsewhere. A 2013 study found increased plasma omega-3 levels and improved peak vertical force in dogs. One of the more consistently evidenced ingredients.
The most common joint supplement ingredients. Evidence is mixed — some trials show improvement in pain scores by day 70, while a 2024 review found insufficient evidence for OA treatment. Individual responses vary. Works best alongside other treatments.
The best-evidenced supplement for dogs overall. EPA and DHA directly target inflammation via the COX and LOX pathways. Recommended as a first-tier option by the American Animal Hospital Association (AAHA) for joint support.
Supplements are not treatments. If your dog has a diagnosed condition or is on medication, talk to your vet before starting. Over-supplementation can cause real harm, especially with fat-soluble vitamins.
