Arthritis and joint injuries are common in horses as they get older just as in people. There are many treatments available such as Legend, Adequan. Injecting joints, stem cell therapy, IRAP, shock wave therapy and nutritionals. The best treatment choice will depend on the exact severity of the arthritis and what you are going to use the horse for. Here at the Stamina Plus Research Center I have had excellent results with Stamina Plus Flex Plus daily nutritional supplement along with shock wave therapy. Stamina Plus Flex Plus has been researched at the research facility for the past 30 years and continues to offer excellent control of inflammation in Equine Joints. This control of inflammation has also been proven to help in COPD and allergic skin problems.
