Vitamin D for COVID-19
8th treatment shown to reduce risk in October 2020
*, now known with p < 0.00000000001 from 119 studies, recognized in 7 countries.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
3,800+ studies for 60+ treatments.
Retrospective 2,908 hospitalized patients in Mexico with vitamin D levels measured on admission, showing significantly lower mortality for patients without vitamin D deficiency.
This is the 100th of 192 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 611 vigintillion).
risk of death, 31.5% lower, HR 0.68, p < 0.001, high D levels 2,337, low D levels 571, adjusted per study, inverted to make HR<1 favor high D levels, >12.5ng/mL, 30 day in-hospital mortality.
hospitalization time, 22.2% lower, relative time 0.78, p < 0.001, high D levels 2,337, low D levels 571.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
