(HealthDayNews) -- Some people with mild to moderate osteoarthritis who take glucosamine or chondroitin sulfate get the same pain relief as people taking anti-inflammatory drugs such as aspirin and ibuprofen, according to the Arthritis Foundation.

But because dietary supplements are unregulated, the quality and content can vary. If you decide to take these supplements after making sure osteoarthritis is the cause of your pain and consulting a doctor, choose products sold by well-established companies and read the labels carefully to make sure the ingredient list makes sense to you.

Recommended doses cost about $1 to $3 per day. Such therapies aren't covered by most insurance companies.
