Osteoarthritis :: Chondroitin, Popular Supplement For Joint Pain, Shows No Benefit

Chondroitin, a dietary supplement used to treat osteoarthritis, is ineffective, a new meta-analysis — a study of published research — finds.

The authors selected 20 trials comparing chondroitin to placebo or no treatment and found that chondroitin had little effect on knee or hip pain caused by arthritis.

Although few adverse side effects were reported, the authors conclude that chondroitin use should “be discouraged.”

In an accompanying editorial, a writer notes that the market in the United States for chondroitin and glucosamine (usually sold together in the U.S.) tops $1 billion/year, and writes that despite these findings, “chondroitin sulfate should not be considered dangerous. If patients say that they benefit from chondroitin, I see no harm in encouraging them to continue taking it as long as they perceive a benefit.”
