Vitamin D for COVID-19

8th treatment shown to reduce risk in October 2020, now with p < 0.00000000001 from 122 studies, recognized in 9 countries.

Lower risk for mortality, ICU admission, hospitalization, progression, recovery, cases, and viral clearance.

No treatment is 100% effective. Protocols combine treatments.

5,100+ studies for 109 treatments. c19early.org

Retrospective 37 hospitalized patients in the USA, showing higher risk of ICU admission with vitamin D deficiency.

This is the 16th of 209 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 293,154,636 vigintillion).

Vitamin D Deficiency is Associated with Increased COVID-19 Severity: Prospective Screening of At-Risk Groups is Medically Indicated

Non-classical actions of Vitamin D are involved in regulation of the immune system including a role in mitigation of excessive in ammation. We hypothesized that vitamin D de ciency existing prior to SARS-CoV-2 infection could contribute to patients developing severe pulmonary compromise as a result of dysfunctional hyperin ammation. Serum vitamin D concentrations of patients experiencing such severe COVID-19 manifestations that they required ICU care at any point of their hospitalization were compared to serum vitamin D concentrations of patients achieving discharge without the need for any ICU care. Having serum vitamin D < 20 ng/mL was signi cantly associated with increased COVID-19 severity, p=0.001. It is conjectured that population groups know to have low serum vitamin D should be prospectively screened for de ciency and if found emergently treated. Such action could both decrease the maximum severity suffered by infected individuals and lessen the strain on medical resources by decreasing the percentage of COVID-19 hospital admissions requiring ICU care.
