Supplementation with omega 3 fatty acids has been shown to reduce joint and systemic inflammation. The study Omega-3s Significantly Improved Canine Arthritis in Double-blind Clinical Trial found that this healthy fat could reduce lameness, joint grinding and pain, decrease swelling and improve puppies lives.
Vitamin E is also a key nutrient for canine relief from arthritic pain and joint damage. A study in the Canadian Journal of Veterinary Research found a marked reduction in in-flammatory joint markers and damage and a trend toward reduced pain.
