A new study published in the journal Arthritis & Rheumatism found chondroitin sulfate successful at reducing pain as well as reducing cartilage loss in the knee for subjects suffering from knee arthritis. Of the 622 subjects aged 45 to 80 years, the average subject was suffering from moderate knee pain due to arthritis. For a period of 2 years, subjects received either prescription-grade chondroitin sulfate or a placebo. Those receiving the chondroitin sulfate as compared with the placebo experienced notable pain relief as well as a 33 percent reduction in the likelihood of experiencing joint narrowing in the knee. While these findings are extremely promising for those suffering from arthritis of the knee and perhaps with arthritis of other joints, it should be noted that subjects were taking prescription-grade chondroitin sulfate and thus, results cannot necessarily be generalized to those chondroitin sulfate products currently being sold as dietary supplements. However, it does appear that the correct chondroitin sulfate can have beneficial effects in those suffering from various forms of arthritis.
