Horses' joints have to cope with extreme forces and very commonly the cartilage is the first part to show wear and tear. The key cartilage nutrients, Glucosamine Sulphate, MSM, Chondroitin Sulphate and Hyaluronic acid (HA) are renowned for their support for the health of both cartilage and the thick synovial fluid that oils the joint. Research suggests that feeding a combination of the key nutrients allows them to work together more effectively than any one nutrient alone however getting the combination right is crucial. Five Star Superflex contains just the right combination of key nutrients in the optimum ratios, developed over twenty five years of working with sound horses.
