Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Glucosamine is commonly used as a dietary supplement to support joint health, particularly in the management of osteoarthritis. Scientific evidence supporting its use is mixed but generally suggests some benefit, especially for mild to moderate osteoarthritis of the knee. Several randomized controlled trials and meta-analyses have evaluated glucosamine's effectiveness. Some studies indicate that glucosamine sulfate, in particular, may reduce pain and improve joint function compared to placebo, though the effect size is often modest. The most robust evidence comes from European studies using prescription-grade glucosamine sulfate. However, other studies, including large trials conducted in the United States, have found little to no significant difference compared to placebo. The variability in study outcomes may be partly due to differences in glucosamine formulations (sulfate vs. hydrochloride), dosages, and study duration.

Glucosamine is a natural compound found in cartilage, and the rationale for its use is based on its role as a building block for glycosaminoglycans, which are components of joint cartilage. While it is generally considered safe, with minimal side effects, authoritative guidelines (such as those from the American College of Rheumatology) remain cautious, recommending glucosamine only as an option for patients who wish to try it and experience benefit, while noting the overall modest and inconsistent clinical effects. In summary, there is scientific evidence to justify the use of glucosamine for joint support, but the strength and consistency of the evidence are moderate at best.
