Numerous studies investigated the efficacy of glucosamine sulfate supplements in people suffering from osteoarthritis. Many of these studies showed promising results - subjects reported decrease joint pain, improved mobility and decreased use of non-steroidal anti-inflammatory drugs. A reader wrote to us and asked if he can use glucosamine sulfate supplements to repair sports injury and enhance athletic performance.
Editor's Note - Glucosamine: No adverse effects
Most of the published studies investigate glucosamine use in older adults as well as post-menopausal women. It is rather difficult to extrapolate these results to young and active athletes. However, since no adverse effects were reported in the past, it does not hurt to try either. Most studies reported positive results in subjects taking 1500mg - 2000 mg of glucosamine sulfate supplements for at least 6 - 8 weeks for joint pain. If you do not see improvement after 8 weeks, it is probably not working for you.
