KER-Flex contains high-quality glucosamine HCl and chondroitin sulfate in a palatable powdered formula to provide broad-spectrum support of joint health. Glucosamine HCl and chondroitin sulfate aid in maintenance of joint integrity, reducing cartilage damage and stimulating cartilage repair. KER-Flex is suitable for all classes of horses engaged in various types of exercise, and is recommended for older, arthritic horses to slow progression of arthritis and help promote a more comfortable future. Progressive degeneration of joints is commonplace, especially in hard-working horses, and degenerative joint disease limits the careers of many performance horses. By the time clinical signs of joint disease are evident, damage has already occurred.
