Glucosamine supplementation repairs joint cartilage
The claim that glucosamine supplementation repairs or preserves joint cartilage is contested in the literature. While several meta-analyses and systematic reviews suggest that glucosamine sulfate can slow joint space narrowing over long-term use, other prominent clinical trials and discussions highlight conflicting results and trial discrepancies regarding its structural and symptomatic efficacy.
The evidence regarding glucosamine and its effect on joint structure (such as joint space narrowing) is mixed. Multiple meta-analyses (e.g., [1], [2], [4], [7]) find positive associations between long-term glucosamine sulfate use and reduced joint space narrowing, supporting structural modification or preservation. However, other trials and large studies (such as the GAIT trial discussed in [6], alongside the methodological debates in [0]) report a lack of efficacy or highlight inconsistencies and high risk of bias across trials. Therefore, the claim is CONTESTED rather than fully supported or refuted.

Long-term meta-analysis results indicate that glucosamine sulfate has a small to moderate protective effect on minimum joint space narrowing after multi-year treatment.

Large trials like GAIT found that glucosamine hydrochloride did not effectively reduce pain or significantly outperform placebo in the overall patient cohort.
