Vitamin D Supplementation Decreased COVID Mortality By 33%
“Vitamin D supplementation during the pandemic was associated with a significant 20% and 28% reduction in laboratory-confirmed COVID-19 rates for vitamin D3and vitamin D2, respectively. Vitamin D3 was associated with a significant 33% decrease in mortality within 30-days of COVID-19 infection. This decrease in COVID-19-related mortality is identical to the 33% observed in the Andalusian data for calcifediol when prescribed 15 days before hospitalization and similar to the 25% associated reduction in mortality for cholecalciferol. For vitamin D2 the associated reduction in mortality was 25% but was not statistically significant. …
When we extrapolate our results for vitamin D3 supplementation to the entire US population in 2020, there would have been approximately 4 million fewer COVID-19 cases and 116,000 deaths avoided.”
