Vitamin D for COVID-19
8th treatment shown to reduce risk in October 2020
*, now known with p < 0.00000000001 from 120 studies, recognized in 8 countries.
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.
Meta analysis of 8 studies with vitamin D levels measured pre-infection or on the day of hospital admission, showing a correlation between the levels and mortality. Authors recommend combining vaccination with vitamin D supplementation to maintain levels above 50 ng/ml. Authors extrapolate to predict a point of zero mortality, however there is no reason to predict a linear relationship where zero mortality would be reached.
12 meta analyses show significant improvements with vitamin D treatment for mortality Argano, Begum, D’Ecclesiis, Hariyanto, Hosseini, Nikniaz, Shah, Xie, mechanical ventilation Hariyanto, Meng, Shah, Xie, ICU admission Hariyanto, Hosseini, Meng, Sartini, Shah, Tentolouris, Xie, hospitalization Argano, severity D’Ecclesiis, Nikniaz, Varikasuvu, Xie, and cases Begum, Sartini, Varikasuvu.
Currently there are 120 vitamin D treatment for COVID-19 studies, showing 36% lower mortality [28‑43%], 16% lower ventilation [-7‑34%], 46% lower ICU admission [28‑60%], 19% lower hospitalization [9‑29%], and 17% fewer cases [9‑24%].
