Zinc for COVID-19

2nd treatment shown to reduce risk in July 2020

^*, now known with p = 0.0000013 from 44 studies, recognized in 11 countries.

Lower risk for mortality, ventilation, hospitalization, progression, recovery, and viral clearance.

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

Retrospective 2,028 COVID patients in the USA, showing significantly lower mortality, ventilation, ICU admission, and progression to ARDS with zinc use, defined as at least one dose from one week prior to admission to 48 hours after admission.
