Evidence points to the fact that higher serum 25(OH)D levels can reduce the risk or severity of acute respiratory tract infections, possibly including COVID-19 – with Vitamin D’s positive impact on innate and acquired immunity.
The researchers cite evidence, which says the, “incidence and mortality of COVID have been far higher in African Americans than in European Americans; after adjustment for age, African Americans are 4.5 times more likely to die from COVID-19 than European Americans.
As for Vitamin D’s effect on reducing Covid-19 patients from advancing into intensive care units, “in a non-randomized intervention study conducted in Spain among hospitalized patients hospitalized for COVID-19, high doses of vitamin D (as 25(OH) D3) were administered in combination with standard care; only 1/50 required admission to the intensive care unit compared to 13/26 comparable control patients.”
