Our fast acting Active-Advanced supplement targets, protects and supports the natural development and maintenance of joints and cartilage in active working dogs. Scientifically crafted in Britain to prevent as well as treat stiff joints, Active-Advanced contains concentrated Green Lipped Mussel to soothe and help lubricate joints. We combine this with high strength Glucosamine and natural Chondroitin to deliver advanced protection against joint wear and tear associated with active working dogs, whilst our carefully selected Manganese supports the active formation and renewal of collagen in your dogs cartilage, tendons and ligaments. In addition, we’ve added Hyaluronic Acid to this supplement, a key component of overall joint health that is naturally found in the synovial fluid surrounding your dogs joints. Hyaluronic Acid binds with water molecules and forms a stiff viscous, which delivers exceptional lubrication of joints as well as aiding shock absorption.
