@TheDao

I’m skeptical of vitamin d supplements in general. So yeah not surprising.

Negative correlations between mean levels of vitamin D (average 56 mmol/L, STDEV 10.61) in each country and the number of COVID-19 cases/1 M (mean 295.95, STDEV 298.7, and mortality/1 M (mean 5.96, STDEV 15.13) were observed

Of the nine studies reviewed, seven (77.8%) showed that COVID-19 infection, prognosis, and mortality were correlated with vitamin D status.

We identified 1542 articles and selected 27. Vitamin D deficiency was not associated with a higher chance of infection by COVID-19 (OR = 1.35; 95% CI = 0.80-1.88), but we identified that severe cases of COVID-19 present 64% (OR = 1.64; 95% CI = 1.30-2.09) more vitamin D deficiency compared with mild cases. A vitamin D concentration insufficiency increased hospitalization (OR = 1.81, 95% CI = 1.41-2.21) and mortality from COVID-19 (OR = 1.82, 95% CI = 1.06-2.58). We observed a positive association between vitamin D deficiency and the severity of the disease.

Most of the articles reviewed showed that blood vitamin D status can determine the risk of being infected with COVID-19, seriousness of COVID-19, and mortality from COVID-19.

Some studies support a link between vitamin D deficiency and worse COVID-19 outcomes.

@Tetcher Old stuff. I only placed this because it is clearly a more thorough study. It debunks the links you send.

 

Correlation is not causation.

"Debunking" dozen of studies that measured the effective levels of vitamin D with a python script that guesses levels of vitamin D based on genomes. Good one.

@Michael569 how many IU of vit D do you supplement daily? Any thoughts about absorption? For me, 30 min of sun exposure is muuuch more powerful than taking 2000 IU. I feel almost euphoric. Maybe it's not vit D only, maybe sun gives much more than vit D .
