Proof, Vitamin-D3 is effective with covid-19

There are three known mechanisms why vitamin D3 works for Covid-19:

Higher doses of vitamin D3 will mitigate the course of influenza and of Covid-19 coronavirus. The researchers outlined 3 mechanisms of how vitamin D works: Evidence that Vitamin D Supplementation Could Reduce Risk of Influenza and COVID-19 Infections and Deaths

1. The best is to take high doses of vitamin D3, 50,000 IU daily for three days, then your maintenance dose of vitamin D3. Ray Schilling’s answer to One of the main reasons so many die from the flu and coronavirus is because of pneumonia. Since we have pneumonia vaccines, why is it not standard procedure to have the public get vaccinated for pneumonia?
2. Vitamin D treatment for coronavirus has been thoroughly examined. Evidence that Vitamin D Supplementation Could Reduce Risk of Influenza and COVID-19 Infections and Deaths This April 2, 2020 publication contains 157 references.
3. An American research group has confirmed everything that I described above: Vitamin D Supplementation Could Prevent and Treat Influenza, Coronavirus, and Pneumonia Infections. This reference has 243 supportive references. The Role of Vitamin D in the Immune System as a Pro-survival Molecule Here is what these authors have noticed:
4. Role of vitamin D3 supplementation in Covid-19 Coronavirus infection: Higher doses of vitamin D3 will mitigate the course of influenza and of Covid-19 coronavirus.

• Maintaining tight epithelial junctions making it more difficult for the Covid-19 coronavirus to penetrate.“
• Killing enveloped viruses through induction of cathelicidin and defensins.” These powerful antiviral polypeptides can kill viruses that have invaded the bloodstream within 1 to 2 days.“…
• And reducing production of proinflammatory cytokines by the innate immune system, thereby reducing the risk of a cytokine storm leading to pneumonia.” It is people who get the viral pneumonia that are at a high risk of death. By bringing the blood level up to the higher range of normal, between 50 and 80 ng/mL, patients that have encountered Covid-19 coronavirus are more likely to survive.
