Turns out vitamin D3 doesn't do shit for COVID-19.

Conclusions and Relevance Among hospitalized patients with severe COVID-19, vitamin D3 supplementation was safe and increased 25-hydroxyvitamin D levels, but did not reduce hospital length of stay or any other relevant outcomes vs placebo. This trial does not support the use of vitamin D3 supplementation as an adjuvant treatment of patients with COVID-19.
