Glucosamine and chondroitin for dogs and cats

Glucosamine belongs to the group of amino sugars and is a natural component of joint cartilage and synovial fluid. Glucosamine has a significant influence on normal joint function. It is important for the formation and supply of connective tissue, tendons, cartilage, joint capsules and synovial fluid.

Healthy cartilage allows the joint surfaces to slide on each other without pain during movement and supports the damping of hard impacts. However, joint changes with loss of glucosamine can occur during growth and in genetically predisposed, active and older animals.

Chondroitin (chondroitin sulphate), like glucosamine, is an endogenous component of joint cartilage. It serves the elasticity and has shock-absorbing properties, and also increases the nutrient permeability for optimal joint supply.

The combination of glucosamine and chondroitin has proven to be particularly effective in supporting the musculoskeletal system and joint metabolism. Supplementing the diet with these substances has been shown to produce positive results in some scientific studies.*
