Quercetin for COVID-19
36th treatment shown to reduce risk in January 2022, now with p = 0.0018 from 9 studies.
No treatment is 100% effective. Protocols combine treatments.
6,600+ studies for 220+ treatments. c19early.org
Systematic review and meta analysis of 6 quercetin RCTs, showing significantly lower hospitalization and ICU admission. Differences for mortality and recovery were not statistically significant.
2 meta-analyses show significant improvements with quercetin for mortality1, ICU admission1,2, and hospitalization1,2.
Currently there are 9 quercetin for COVID-19 studies, showing 79% lower mortality [4‑95%], 89% lower ventilation [-92‑99%], 68% lower ICU admission [7‑89%], 36% lower hospitalization [5‑56%], and 93% fewer cases [9‑99%].
