Update on glucosamine

Osteoarthritis is the most common form of arthritis. Recent evidence suggests that glucosamine sulfate and chondroitin sulfate may each have a disease-modifying effect in this condition, delaying the loss of articular cartilage. There is much information (of variable quality) about such products on the internet, in the lay press and in health food shops, which has fostered widespread public awareness and led to prescribers being asked frequently to advise on their use. This article will assist those who prescribe treatment for osteoarthritis.
