Another COVID-19 and Vitamin D Meta-Analysis with Similar Results

Published on December 21, 2021

Review of nearly two million individuals from 72 combined studies further supports the link between low vitamin D and increased susceptibility to COVID-19 infection, severity and mortality

A number of studies, such as those included in our new Vitamin D & COVID-19: A Summary of Published Research eBook and on our blog, have provided much evidence showing the significant effect that vitamin D status has on COVID-19 disease progression and outcomes, where higher vitamin D levels can reduce the risk of infection and severity and help prevent death. Findings from yet another meta-analysis, which included data from nearly two million participants from 72 combined studies, further support the connection between vitamin D and the risks of COVID-19. This analysis is reviewed below and will be added to our eBook in the next revision.

Another Vitamin D and COVID-19 Meta-Analysis, with Similar Conclusions

A total of 72 studies with data from 1,976,099 individuals was included in the meta-analysis by Dissanayake et al., which was published this month (December, 2021).

The study found that those with vitamin D deficiency/insufficiency had a

107% higher risk of death due to COVID-19 (p=0.003)

It is important to note that vitamin D deficiency/insufficiency was used to describe vitamin D insufficiency or deficiency of any severity, and was not broken down by specific vitamin D level cut-off points. All findings point to significantly higher risk with lower vitamin D levels. Timing of vitamin D testing in relation to the COVID-19 outcome(s) measured, and the cut-off vitamin D levels used to define deficiency/insufficiency, seemed to have the greatest effect on individual study risk analysis outcomes.
