Yes, adequate vitamin D is important, but people are going to start OD’ing on the stuff. More is better, but too much is not.
Vitamin D is actually a hormone, and very beneficial in creating immunity. It is cheap, so take every day.
I believe there were also some stats that said blacks usually had lower Vit D counts than whites.
Here are the study results:
Results
“Of 1176 patients admitted, 253 had records of a 25(OH)D level prior to COVID-19 infection. A lower vitamin D status was more common in patients with the severe or critical disease (<20 ng/mL [87.4%]) than in individuals with mild or moderate disease (<20 ng/mL [34.3%] p < 0.001). Patients with vitamin D deficiency (<20 ng/mL) were 14 times more likely to have severe or critical disease than patients with 25(OH)D ≥40 ng/mL (odds ratio [OR], 14; 95% confidence interval [CI], 4 to 51; p < 0.001).”
It may be that the worst effects of Covid could have been avoided by Vitamin D supplementation.
4,000 mg daily is ideal.
“vitamin D3 has such a strong impact on disease severity that they can predict how people would fare if infected based on nothing more than their ages and vitamin D levels”
Just got my bloodwork results 51%, but I do take D2 as a supplement.
