Horses\' joints have to cope with extreme forces and it is commonly the cartilage that is the first part to show wear and tear. The key cartilage nutrients, Glucosamine Sulphate, MSM, Chondroitin Sulphate and Hyaluronic acid (HA) are well known for their support for the health of both cartilage, and the thick synovial fluid that oils the joint.Research recommends that feeding a combination of the key nutrients allows them to work together more effectively than any one nutrient alone. Getting the combination right is crucial.Five Star Superflex:Contains the right combination of key nutrients in the optimum ratiosIs developed over 25 years of working with sound horsesNaturally sourced antioxidants to work synergistically with Glucosamine and MSM to support joint healthWeight: 800gHorses & Poniesg per dayscoops per dayLoading rate (3-10 days)266Standard Maintenance133Low Maintenance82CompositionGlucosamine (from crustaceans), Methyl sulphonyl methane, Saxifragales, Wheat protein, Rapeseed oil, Hyaluronic acid, Chondroitin sulphate, Sodium chloride.
