ABOUT OUR INGREDIENTS : Perna canaliculus is a green-lipped mussel from an exclusive New Zealand source. Unlike Perna extract-based products and mussel powders, which may lack important fatty acids and other bioactive components (e.g. defatted powders or extracts), the entire organism is utilized in our Perna. Glucosamine has been shown to support the production of glycosaminoglycans (GAGs) within the cartilage matrix and synovial fluid. As your dog ages, there is a decrease in the production of GAGs, which can result in joint stress, thinning of synovial fluid, and the breakdown of connective tissue. Glucosamine also supports bladder and urinary tract health by supporting the integrity of the mucosal lining. Chondroitin Sulfates helps support the proper structure and function of healthy connective tissues and joints. Sulfates in these products are derived from Porcine Cartilage which is a rich source of biologically-active Chondroitin Sulfates. MSM is a source of sulfur. It supports the structure of joints and connective tissue. Increased availability of MSM is linked to comfort and mobility, as well as the support of collagen production. Manganese is an essential mineral for the formation of collagen, GAGs, and proteoglycans, all of which support required cartilage integrity. A lack of manganese can lead to inefficient production of GAGs within the joints. Vitamin C The antioxidants in our formula help support immune system response, proper detoxification function, free radical neutralization, as well as provide support for a healthy inflammatory response.
