In one study done on glucosamine and chondroitin, patients with osteoarthritis experienced the same effects after taking either glucosamine alone, glucosamine with chondroitin or a placebo, notes Dr. Canale. Some studies do show that there is improvement in some patients, but the results are inconclusive. There is no risk in trying the supplement, and results are different for each individual. Even though most supplements contain glucosamine chloride, studies show glucosamine sulfate to be more effective than glucosamine chloride as far as lowering pain scores.

The best glucosamine and chondroitin should also contain at least 90 percent glucosamine and chondroitin, pass a dissolution test used by the U.S. Pharmacopeia, and fall within acceptable limits for heavy metal contaminants, explains Consumer Reports. The company tested 16 products and found that all contained the labeled amount of glucosamine and fell within the acceptable limits of heavy metals. It found that nine products met all the criteria, with the cheapest supplement containing glucosamine sulfate being Now Extra Strength.
