Statistically significant lower risk is seen for ventilation, hospitalization, recovery, cases, and viral clearance. 11 studies from 10 independent teams in 8 countries show significant improvements.
Meta analysis using the most serious outcome reported shows 43% [24‑57%] lower risk. Results are similar for Randomized Controlled Trials and higher quality studies. Early treatment is more effective than late treatment.
Results are very robust — in exclusion sensitivity analysis 11 of 14 studies must be excluded to avoid finding statistically significant efficacy in pooled analysis.
No treatment or intervention is 100% effective. All practical, effective, and safe means should be used based on risk/benefit analysis. Multiple treatments are typically used in combination, and other treatments may be more effective. The quality of non-prescription supplements can vary widely1,2.
