Popular nutritional supplements glucosamine and chondroitin sulfate don’t slow the progression of arthritis, a 2-year study finds. Though a combination of the two is the nation's sixth-highest-selling dietary supplement, they didn’t cut cartilage loss any better than sugar pills in osteoarthritis patients, reports USA Today, confirming the findings of earlier research.
