Glucosamine HCL is the key building block for making cartilage. Recent reports in veterinary journals have validated the benefits of glucosamine in maintaining joint health and supporting mobility and activity in dogs of all ages and sizes.

Chondroitin sulfate protects existing cartilage and slows its break down.

Methysulfonylmethane (MSM) is a natural anti-inflammatory agent that provides sulfur essential in the formation of cartilage.

Hyaluronic acid helps maintain the viscosity of joint fluid.

Vitamin C (ascorbic acid) is a potent antioxidant that is also important for the formation of bone and cartilage.

Manganese, copper and zinc are essential in biochemical reactions that help form cartilage.

Best Use - For added joint support in athletic or overweight medium or large dogs of all ages
