Dietary Supplements for Osteoarthritis
Osteoarthritis, which affects an estimated 27 million Americans, is a leading cause of disability in older adults. Because the general population is aging and obesity, a major risk factor, is increasing in prevalence, the occurrence of osteoarthritis is on the rise. Clinical practice guidelines issued by the American College of Rheumatology recommend aerobic exercise and/or strength training, weight loss (if overweight), and a number of pharmacological and non-pharmacological modalities for treating OA of the knee, hip, or hand.
Many people with OA report trying various dietary supplements in an effort to relieve pain and improve function. However, there is no convincing evidence that any dietary supplement helps with OA symptoms or the underlying course of the disease. This issue of the digest summarizes current scientific evidence about several dietary supplements most often used by people with OA, including glucosamine and chondroitin sulfate, Dimethyl Sulfoxide (DMSO) and Methylsulfonylmethane (MSM), S-Adenosyl-L-methionine (SAMe), and herbal remedies.
