Claim: There is a correlation between vitamin D deficiencies and higher COVID-19 mortality rates

Q1: What does vitamin D do?
A1: Aside from building healthy bones, vitamin D can boost the immune system by suppressing what’s called a cytokine storm — severe inflammation that occurs when the immune system becomes overactive and releases too many cytokine proteins.

Q2: How might this help COVID-19?
A2: Backman said cytokine storms may contribute to COVID-19 deaths because the storms can damage people’s lungs. An April 17, 2020 article on WebMD also indicated that patients with severe COVID-19 symptoms had high levels of cytokines in their system.

The idea, then, is that vitamin D could suppress a catastrophic immune response and prevent people from developing severe COVID-19 symptoms that lead to death.

Q3: Is the link between lower vitamin D levels and deaths from COVID-19 backed by research?
A3: Early studies into vitamin D suggests it may curb the severity of COVID-19 symptoms and reduce mortality rates. Further research is needed to examine the issue, and vitamin D is not a cure for the coronavirus. 

But Grothman did not say it was a cure, only that there was a correlation. One expert noted the correlation was "significant"

justification: The third source shows that there is a correlation between vitamin D and covid deaths. The source is a credible one. Therefore the claim is supported.
