Livstrong Shark Cartilage powder is a natural source of glucosamine and chondroitin providing a natural support for your pet's joints and inflammation. The ingredient is pure shark cartilage powder and each teaspoon contains approximately 2,000 mg of shark cartilage. Results are normally seen in 2-3 weeks so at the 4th week we suggest that you slowly reduce the amount to the maintenance level for the continued well-being of your pet. Livstrong Shark Cartilage powder is veterinarian recommended and is sourced ethically and sustainably in Australia.
