Glucosamine is extracted from a material (chitin) present in the shells of crabs, oysters, and shrimp. Glucosamine can be applied topically in a cream or salve or taken in tablet or capsule form, usually as glucosamine sulfate, but sometimes as glucosamine hydrochloride. Glucosamine often is taken with chondroitin sulfate.

Evidence is conflicting. Some evidence suggests it has both pain-relieving and disease-modifying effects, whereas other large and well-designed studies show it to be of no benefit. One large study has shown that glucosamine hydrochloride is beneficial when combined with chondroitin sulfate. Evidence supports use of glucosamine sulfate from a specific manufacturer, Rotta Research Laboratorium, for mild to moderate osteoarthritis in the knee when taken for at least 6 months. The benefit of glucosamine for severe osteoarthritis in the knee or osteoarthritis in other locations is less clear.
