(Newser) – 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.

But researchers aren’t convinced the supplements are useless and say the study could be refined. “I'm most worried about throwing out something that may possibly be a benefit,” says the lead investigator.
