This study assumed that vitamin D for bone health should be applied to COVID-19 (< 20ng)
The human body needs different levels of vitamin D to fight different health problems
For example, need 50 ng to fight Infections
Human bodies appear to need at least 40 ng to fight COVID-19
The study mentions that vitamin D supplementation
(for any dose size, any duration), reduced risk of severe COVID-19 by 3.7 X

Highlights
- Vitamin D modulates the systemic inflammatory response through interaction with immune system.
- We systematically reviewed studies about vitamin D3 and risk and mortality for COVID-19 infection
- Reduced vitamin D values resulted in a higher infection risk, mortality and severity COVID-19 infection.
Vitamin D modulates the systemic inflammatory response through interaction with immune system. As such, it has a possible protective role against the risk of respiratory tract infections and other diseases. It may be useful in particular, during COVID-19 pandemic. PubMed, the Cochrane Library, and EMBASE were searched from inception until January 31, 2021, for observational or clinical studies reporting the prognosis (and therapeutic effect) of COVID-19 infection in patients with deficient vitamin D levels. The infection rate, severity, and death from COVID-19 infection were pooled to provide an odds ratio with a 95% confidence interval (OR 95% CI). An OR > 1 was associated with the worst outcome in deficient compared with nondeficient patients.
We assessed the association between vitamin D and risk, severity, and mortality for COVID-19 infection, through a review of 43 observational studies. Among subjects with deficient vitamin D values, risk of COVID-19 infection was higher compared to those with replete values (OR = 1.26; 95% CI, 1.19-1.34; P < .01). Vitamin D deficiency was also associated with worse severity and higher mortality than in nondeficient patients (OR = 2.6; 95% CI, 1.84-3.67; P < .01 and OR = 1.22; 95% CI, 1.04-1.43; P < .01, respectively).
Reduced vitamin D values resulted in a higher infection risk, mortality and severity COVID-19 infection. Supplementation may be considered as preventive and therapeutic measure.
