Vitamin D for COVID-19
8th treatment shown to reduce risk in October 2020, now with p < 0.00000000001 from 125 studies, recognized in 9 countries.
No treatment is 100% effective. Protocols combine treatments.

Retrospective 317 COVID-19 hospitalized patients in Iran, showing mortality associated with lower vitamin D levels.
This is the 108th of 214 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 4,225,339,384 vigintillion).
risk of death, 41.9% lower, RR 0.58, p = 0.07, high D levels (≥20ng/mL) 16 of 163 (9.8%), low D levels (<20ng/mL) 26 of 154 (16.9%), NNT 14.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
