Less than a week after
JAMA Network Open published a small study showing zinc and vitamin C were not associated with improved mild COVID-19 infections, a 240-person
JAMA study also found that a single dose of vitamin D did not have any significant effect on moderate to severe COVID-19 infections.
The study, published yesterday by Igor Murai, PhD, a Sao Paul rheumatologist, and colleagues, reported that hospital stay was a median 7.0 days for both those in the intervention and the placebo group, and while there were differences up to 8.4 percentage points across in-hospital mortality, intensive care unit (ICU) admission, and mechanical ventilation needs, they were all statistically not significant.
