Summary

This study looks at whether adding a dietary supplement to an exercise program can reduce pain and improve movement in people with knee osteoarthritis. About 93 adults with mild to moderate knee arthritis will be split into three groups: supplement alone, supplement plus exercise, or placebo plus exercise. Researchers will compare the groups to see if the combination works better than either alone.
