Comparative Effectiveness of Nutritional Supplements in the Treatment of Knee Osteoarthritis: A Network Meta-Analysis
Nutrients (2025) · Meta analysis · n=4599
Bayesian rankings indicated Boswellia had the highest probability of being most effective for pain and stiffness, with krill oil and curcumin showing potential for function improvement.

Comparative efficacy and tolerability of nutraceuticals for depressive disorder: A systematic review and network meta-analysis

Network meta-analysis of 192 trials in 17,437 adults with depressive disorder, covering 44 nutraceuticals.
Effects of dietary supplements on patients with osteoarthritis: A systematic review and network meta-analysis
Journal of integrative medicine (2025) · Meta analysis · n=2455
In the WOMAC pain score, the SUCRA of passion fruit peel extract was 91% (mean difference [MD]: -9.2; 95% confidence interval [CI]: [-16.0, -2.3]), followed by methylsulfonylmethane (89%), undenatured type II collagen (87%), collagen (84%), and Lanconone (82%).
Methylsulfonylmethane Improves Knee Quality of Life in Participants with Mild Knee Pain: A Randomized, Double-Blind, Placebo-Controlled Trial
Nutrients (2023) · Rct · n=88
The total scores at 12 weeks in the MSM and placebo groups as the primary outcome were significantly different (p = 0.046).
The Effect of Daily Methylsulfonylmethane (MSM) Consumption on High-Density Lipoprotein Cholesterol in Healthy Overweight and Obese Adults: A Randomized Controlled Trial
Nutrients (2021) · Rct · n=22
The primary finding of this work shows that high-density lipoprotein cholesterol was elevated at 8 and 16 weeks of daily MSM consumption compared to baseline, (p = 0.008, p = 0.013).
The two points come from two separate placebo-controlled trials, not from one trial comparing doses. At 2,000 mg a day (ten 200 mg tablets) for 12 weeks, 88 Japanese adults with mild knee pain improved their total knee score more than placebo (PMID 37447322, p = 0.046). At 6,000 mg a day (3 g twice daily) for 12 weeks, 50 adults with knee osteoarthritis had less WOMAC pain and better physical function than placebo, with no change in stiffness or total symptoms and no major adverse events (PMID 16309928). The populations and scales differ, so the curve is drawn flat: the trials cannot show whether 6 g works better than 2 g. A 16-week trial at 6 g a day found no difference from placebo in blood counts, liver and kidney markers, weight or blood pressure (PMID 31331587). No optimal dose has been established.
AI-estimated from published studies. Interpret as directional guidance.
Curcumin has a higher evidence score (7.5/10 vs 6/10) and wins in 2 of 3 categories.
For inflammation-related symptoms, Curcumin has a higher relevance score (90 vs 40).
No documented interaction was found in the data searched. This does not establish that this exact combination is safe.
The honest tier list — proven staples vs situational vs mostly marketing. The hub the other guides feed into.
Curcumin, omega-3, UC-II collagen, Boswellia vs the old glucosamine default — and OA vs RA.
