Large-scale, methodologically sound trials indicate that the symptomatic benefit of chondroitin is minimal or nonexistent.
The Safety and Efficacy of Glucosamine and/or Chondroitin in Humans: A Systematic Review
Nutrients (2025) · Systematic review · n=146
Of the 2013 articles screened, 146 studies were included in our review, with nearly 60% being randomized controlled trials and most conducted in Europe, Asia, or the U.S.
Systematic review and network meta-analysis on the efficacy and safety of parmacotherapy for hand osteoarthritis
PloS one (2024) · Meta analysis · n=3965
GCSB-5, a specific herbal complex that mainly regulate pain in hand osteoarthritis, showed the greatest reduction in pain [WMD = -13.00, 95% CI (-26.69, 0.69)].
S-Adenosylmethionine for osteoarthritis of the knee or hip
The Cochrane database of systematic reviews (2009) · Meta analysis · n=656
For pain, the analysis indicated a small SMD of -0.17 (95% CI -0.34 to 0.01), corresponding to a difference in pain scores between SAMe and placebo of 0.4 cm on a 10 cm VAS, with no between trial heterogeneity (I(2) = 0).
Efficacy of Pharmacological Interventions in Milder Depression: A Systematic Review and Meta-Analysis
Neuropsychopharmacology reports (2025) · Meta analysis · n=1049
A meta-analysis found no significant difference in response rates between the two treatments (risk ratio [RR] = 0.96, 95% CI: 0.78-1.18) or dropout rates (RR = 1.08, 95% CI: 0.62-1.88).
S-Adenosylmethionine (SAMe) for Liver Health: A Systematic Review
Nutrients (2024) · Systematic review · n=15
The most common doses were SAMe 1000 mg or 1200 mg per day with or without another treatment or natural supplement.
Large meta-analyses show minimal to nonexistent benefits. Effects appear modest at best, with significant study heterogeneity. Combination with glucosamine may be more effective than chondroitin alone.
Meta-analysis of 656 patients showed small effect size (SMD -0.17) corresponding to only 0.4cm improvement on 10cm pain scale. Effect is modest and barely reaches statistical significance threshold.
