Download Meta Analysis
Umbrella meta analysis of 13 meta analyses showing significantly lower mortality with vitamin D supplementation, and significantly higher mortality, infection risk, and severity with vitamin D deficiency in COVID-19 patients. Lower vitamin D levels were also associated with poor prognosis. No significant association was found between vitamin D levels and COVID-19 positivity.
19 meta analyses show significant improvements with vitamin D treatment for mortality1-13, mechanical ventilation1,5,6,11,14-16, ICU admission1,3,5,6,9,11,13-18, hospitalization11, severity2,4,5,10,19, and cases7,18,19.
Currently there are 126 vitamin D treatment for COVID-19 studies, showing 38% lower mortality [31‑45%], 19% lower ventilation [-3‑36%], 45% lower ICU admission [28‑58%], 19% lower hospitalization [9‑29%], and 17% fewer cases [9‑24%].

Objectives: Several meta-analyses have suggested the beneficial effect of vitamin D on patients infected with SARS-CoV-2. This umbrella meta-analysis aims to evaluate influence of vitamin D supplementation on clinical outcomes and the mortality rate of COVID-19 patients. Design: Present study was designed as an umbrella meta-analysis. The following international databases were systematically searched till March 2023: Web of Science, PubMed, Scopus, and Embase. Settings: Random-effects model was employed to perform meta-analysis. Using AMSTAR critical evaluation tools, the methodological quality of the included meta-analyses was evaluated. Participants: Adult patients suffering from COVID-19 were studied. Results: Overall, 13 meta-analyses summarizing data from 4 RCTs and 9 observational studies were identified in this umbrella review. Our findings revealed that vitamin D supplementation and status significantly reduced mortality of COVID-19 [Interventional studies: (ES= 0.42; 95% CI: 0.10, 0.75, p <0.001; I 2 = 20.4%, p=0.285) and observational studies (ES= 1.99; 95% CI: 1.37, 2.62, p <0.001; I 2 = 00.0%, p=0.944). Also, vitamin D deficiency increased risk of infection and disease severity among patients. Conclusion: Overall, vitamin D status is a critical factor influencing the mortality rate, disease severity, admission to ICU and being detached from mechanical ventilation. It is vital to monitor the vitamin D status in all patients with critical conditions including COVID patients.
