Superflex is the perfect combination: a scientifically balanced blend of easily absorbed glucosamine and chondroitin, the highest quality MSM, plus the added benefits of a powerful antioxidant formula. Horse joints are subjected to extreme forces, and it is often the cartilage that first shows signs of wear. With thinner synovial fluid and a disruption in the protective cartilage layer, the process of breakdown begins. The initial signs are often difficult to recognize, but gradually, wear and tear builds to the point that the horse can no longer work effectively. The key nutrients support healthy and flexible joints. Research shows that combining key nutrients is more effective than using any single nutrient alone. Five Star Superflex contains the right combination of key nutrients in optimal ratios, developed over more than twenty-five years of working with healthy horses.
