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.

The Cochrane database of systematic reviews (2014) · Meta analysis · n=5980
Seventeen studies of confirmatory design (sample and effect sizes pre-specified) were mostly at moderate risk of bias.
Efficacy of Zinc Supplementation in the Management of Primary Dysmenorrhea: A Systematic Review and Meta-Analysis
Nutrients (2024) · Meta analysis · n=739
Zinc supplementation significantly reduced pain severity compared to placebo (Hedges's g = -1.541; 95% CI: -2.268 to -0.814; p < 0.001), representing a clinically meaningful reduction in pain.
Effects of Daily Zinc Alone or in Combination with Other Nutrient Supplements on the Risk of Malaria Parasitaemia: A Systematic Review and Meta-Analysis of Randomised Controlled Trials
Nutrients (2023) · Meta analysis · n=1339
The effect sizes, represented as risk ratios (RRs) with 95% confidence intervals (CIs), were standardised by transforming them into log RRs and then pooling them using a fixed-effects or random-effects model depending on the heterogeneity across studies.
Prevalence of Zinc Deficiency in Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis
Nutrients (2022) · Meta analysis · n=806
Pooled analyses by the IBD subgroup showed a total population of 1677 with CD, for an overall mean zinc deficiency prevalence of 54% and 95% confidence intervals (CI) ranging from 0.51 to 0.56, versus 41% (95%CI 0.38-0.45) in the UC population (n = 806).
The Cochrane review of oral herbal therapies (PMID 24848732) found high-quality evidence from two trials (85 people) that 100 mg a day of an enriched Boswellia serrata extract for 90 days cut pain by 17 points on a 0 to 100 scale against placebo, with fewer adverse events than placebo in one trial. Effectiveness is that pain reduction. A 250 mg dose of enriched extract showed possible benefit in low-quality evidence from a single small study, so it is plotted flat, not higher. Trials of 100 mg Aflapin a day for 30 and 180 days also reduced knee pain against placebo (PMID 35512759, 39700461). A 999 mg dose of a non-enriched extract is a different product and is not plotted. The Cochrane authors state that the optimal daily dose is still to be determined.
AI-estimated from published studies. Interpret as directional guidance.
Zinc has a higher evidence score (8.5/10 vs 7.5/10) and wins in 2 of 3 categories.
For pms relief, Zinc has a higher relevance score (90 vs 65).
No documented interaction was found in the data searched. This does not establish that this exact combination is safe.
