Vitamin D for COVID-19
8th treatment shown to reduce risk in October 2020
 
*, now known with p < 0.00000000001 from 120 studies, recognized in 7 countries.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.

Retrospective 464 patients in United Arab Emirates showing low D levels at first hospital visit associated with higher COVID-19 severity and mortality.
This is the 66th of 194 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 2470 vigintillion).
risk of death, 59.3% lower, RR 0.41, p = 0.048, high D levels 16 of 337 (4.7%), low D levels 10 of 127 (7.9%), adjusted per study, inverted to make RR<1 favor high D levels, odds ratio converted to relative risk, >=12ng/mL.
risk of severe case, 33.2% lower, RR 0.67, p = 0.005, high D levels 337, low D levels 127, adjusted per study, inverted to make RR<1 favor high D levels, odds ratio converted to relative risk, >=12ng/mL.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates

COVID-19 Disease Severity and Death in Relation to Vitamin D Status among SARS-CoV-2-Positive UAE Residents

Insufficient blood levels of the neurohormone vitamin D are associated with increased risk of COVID-19 severity and mortality. Despite the global rollout of vaccinations and promising preliminary results, the focus remains on additional preventive measures to manage COVID-19. Results conflict on vitamin D's plausible role in preventing and treating COVID-19. We examined the relation between vitamin D status and COVID-19 severity and mortality among the multiethnic population of the United Arab Emirates. Our observational study used data for 522 participants who tested positive for SARS-CoV-2 at one of the main hospitals in Abu Dhabi and Dubai. Only 464 of those patients were included for data analysis. Demographic and clinical data were retrospectively analyzed. Serum samples immediately drawn at the first hospital visit were used to measure serum 25-hydroxyvitamin D [25(OH)D] concentrations through automated electrochemiluminescence. Levels < 12 ng/mL were significantly associated with higher risk of severe COVID-19 infection and of death. Age was the only other independent risk factor, whereas comorbidities and smoking did not contribute to the outcomes upon adjustment. Sex of patients was not an important predictor for severity or death. Our study is the first conducted in the UAE to measure 25(OH)D levels in SARS-CoV-2-positive patients and confirm the association of levels < 12 ng/mL with COVID-19 severity and mortality.
