Glucosamine for Joint Health: A Systematic Evidence Review

Glucosamine may help some people with osteoarthritis feel a little less pain or stiffness, but the benefit is usually modest and it does not reliably improve how well the joint works. The stronger claims, like protecting cartilage or slowing joint damage, are not well supported here. If you try it, treat it as a symptom experiment, not a joint-rebuilding therapy: use it for a defined period, and if your pain and mobility do not clearly improve, move on.
