Vitamin D for COVID-19
8th treatment shown to reduce risk in October 2020
 
*, now known with p < 0.00000000001 from 118 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.

TriNetX PSM retrospective 42,674 COVID-19 outpatients, showing higher mortality and hospitalization with vitamin D deficiency.
This is the 189th 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, 42.8% lower, HR 0.57, p = 0.005, high D levels (≥20 ng/mL) 8,300, low D levels (<20 ng/mL) 8,300, inverted to make HR<1 favor high D levels (≥20 ng/mL), propensity score matching.
risk of hospitalization, 18.7% lower, HR 0.81, p < 0.001, high D levels (≥20 ng/mL) 8,300, low D levels (<20 ng/mL) 8,300, inverted to make HR<1 favor high D levels (≥20 ng/mL), propensity score matching.
ER visit, 10.2% lower, HR 0.90, p = 0.03, high D levels (≥20 ng/mL) 8,300, low D levels (<20 ng/mL) 8,300, inverted to make HR<1 favor high D levels (≥20 ng/mL), propensity score matching.
risk of PASC, 2.0% higher, HR 1.02, p = 0.93, high D levels (≥20 ng/mL) 8,300, low D levels (<20 ng/mL) 8,300, inverted to make HR<1 favor high D levels (≥20 ng/mL), propensity score matching.
