Clinical trials are proving that Vitamin D fights COVID-19 in hospitals includes
5 very successful Clinical Trials of Vitamin D fighting COVID-19 have been published as of Oct 2021 '

  1. COVID-19 defeated by calcifediol form of Vitamin D in Spain - pilot RCT Aug 29, 2020
    • Trial used a faster-acting form of vitamin D which is only available by prescription
  2. COVID-19 defeated 3x faster by 420,000 IU Vitamin D nanoemulsion – RCT Nov 12, 2020 - supplier not stated
  3. 2X fewer COVID-19 deaths observed with 300,000 IU of vitamin D

The study was reviewed in Medscape
"This study shows how severe a problem this is," Teitelbaum told Medscape Medical News. "A 3.7-fold increase in death rate if someone's vitamin D level was below 20 [ng/mL] is staggering. It is arguably one of the most important risk factors to consider."

Objectives
Vitamin D deficiency was previously correlated with incidence and severity of coronavirus disease 2019 (COVID-19). We investigated the association between serum 25-hydroxyvitamin D (25(OH)D) level on admission and radiologic stage and outcome of COVID-19 pneumonia.

Methods
A retrospective observational trial was done on 186 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)–infected individuals hospitalized from March 1, 2020, to April 7, 2020, with combined chest computed tomography (CT) and 25(OH)D measurement on admission. Multivariate regression analysis was performed to study if vitamin D deficiency (25(OH)D <20 ng/mL) correlates with survival independently of confounding comorbidities.

Results
Of the patients with COVID-19, 59% were vitamin D deficient on admission: 47% of females and 67% of males. In particular, male patients with COVID-19 showed progressively lower 25(OH)D with advancing radiologic stage, with deficiency rates increasing from 55% in stage 1 to 74% in stage 3. Vitamin D deficiency on admission was not confounded by age, ethnicity, chronic lung disease, coronary artery disease/hypertension, or diabetes and was associated with mortality (odds ratio [OR], 3.87; 95% confidence interval [CI], 1.30-11.55), independent of age (OR, 1.09; 95% CI, 1.03-1.14), chronic lung disease (OR, 3.61; 95% CI, 1.18-11.09), and extent of lung damage expressed by chest CT severity score (OR, 1.12; 95% CI, 1.01-1.25).

Conclusions
Low 25(OH)D levels on admission are associated with COVID-19 disease stage and mortality.
