Scientific evidence indicates vitamin D reduces infections & deaths
To all governments, public health officials, doctors, and healthcare workers,

Research shows low vitamin D levels almost certainly promote COVID-19 infections, hospitalizations, and deaths. Given its safety, we call for immediate widespread increased vitamin D intakes.
Vitamin D modulates thousands of genes and many aspects of immune function, both innate and adaptive. The scientific evidence1 shows that:
Higher vitamin D blood levels are associated with lower rates of SARS-CoV-2 infection.
Higher D levels are associated with lower risk of a severe case (hospitalization, ICU, or death).
Intervention studies (including RCTs) indicate that vitamin D can be a very effective treatment.
Many papers reveal several biological mechanisms by which vitamin D influences COVID-19.
Causal inference modelling, Hill’s criteria, the intervention studies & the biological mechanisms indicate that vitamin D’s influence on COVID-19 is very likely causal, not just correlation.
