Chondroitin sulphate is a naturally occurring molecule which is well known for easing the symptoms of osteoarthritis and other joint conditions. It acts as a natural anti-inflammatory and also blocks the enzymes that attack the joints during osteoarthritis.
Chondroitin is a component of animal cartilage and meat and is therefore present in small amounts in virtually all dog foods. Many dog foods, especially those designed for older dogs or large breed dogs, have added chondroitin to provide additional joint support. Supplemented chondroitin sulphate is manufactured from animal sources, such as cow cartilage.
