Glucosamine is a dietary supplement which is made from shellfish or prepared in the laboratory. It comes in two forms, glucosamine sulphate and glucosamine hydrochloride. It’s also known as Glucose-6-phosphate, GS, amino monosaccharide, sulfated monosaccharide, Chitosamine and D-glucosamine.
How does it work?
Glucosamine is found naturally in your body. It plays an important role in making glycosaminoglycans and glycoproteins, which are the building blocks of many structures of your joints, including your ligaments, tendons, cartilage and the synovial fluid. It’s been suggested that the way these joint structures are built and maintained contributes to the development and progression of osteoarthritis. Studies in animals have found that glucosamine can both delay the breakdown of cartilage and repair it when it’s damaged.
How effective is it?
The role of glucosamine in the treatment of osteoarthritis has been studied in at least 21 randomised controlled trials. Despite some mixed results, the majority of trials showed glucosamine sulphate has significant clinical benefits when compared to a placebo or non-steroidal anti-inflammatory drugs (NSAIDs). Evidence from trials on glucosamine hydrochloride is scarce and much less convincing.
