Vitamin A for COVID-19
39th treatment shown to reduce risk in June 2023
 
*, now known with p = 0.045 from 12 studies.
Lower risk for recovery.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
4,000+ studies for 60+ treatments. c19early.org
Statistically significant lower risk is seen for recovery. 6 studies from 5 independent teams in 3 countries show statistically significant improvements.
Meta analysis using the most serious outcome reported shows 36% [1‑59%] lower risk. Results are similar for Randomized Controlled Trials, higher quality studies, and peer-reviewed studies. Results are consistent with early treatment being more effective than late treatment.
6 sufficiency studies analyze outcomes based on serum levels, showing 80% [52‑92%] lower risk for patients with higher vitamin A levels.
In exclusion sensitivity analysis, statistical significance is lost after excluding only one of 12 studies in pooled analysis.
The European Food Safety Authority has found evidence for a causal relationship between the intake of vitamin A and optimal immune system function Galmés, Galmés (B).
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 widely Crawford, Crighton.
