Sunshine or Supplements
If you live on planet earth, where a pandemic is ripping through humanity, killing and harming vast numbers of persons of all ages, especially the elderly, and you are not either taking vitamin D supplements or getting plenty of sunshine on skin, you are putting yourself in grave danger of suffering and death, unnecessarily.
19 studies, by 116 total authors, show that having high blood levels of vitamin D reduces Covid-19 risks, including risk of infection [7, 8, 9, 11, 12, 14, 16], risk of having a severe case [1, 3, 4, 5, 15, 17], of needing hospitalization, ICU care, and/or mechanical ventilation [2, 10, 14, 15], as well as the risk of dying from Covid-19 [4, 6, 7, 9, 12, 13, 17, 18, 19].
Why would anyone, knowing this, not take vitamin D supplements to increase their blood levels to obtain the risk reduction found by those 19 studies?
In addition to reducing various types of risk related to Covid-19, vitamin D has other health benefits. Studies have shown that a high intake of vitamin D reduces risk of stroke , multiple sclerosis , rheumatoid arthritis , type 2 diabetes , breast cancer , prostate cancer , colon cancer , and all-cause mortality .
If, for some reason, you cannot obtain vitamin D supplements, then you can make vitamin D by exposing your skin to sunshine (not through a window pane). Get outside and expose skin to sunshine. This produces plenty of vitamin D with one hour of sunshine at least three days per week. If you have light skin and sunburn easily, reduce to one-half hour.
Religious leaders and government officials are going to need to help relax certain customs, in some regions, which prevent persons, especially women, from exposing skin to sunshine. This is necessary and should be acceptable, for the sake of those who are suffering.
What would happen if EVERYONE took this advice? The pandemic would be reduced by many fewer cases and many fewer deaths. A vast amount of suffering and death would be averted. By vitamin D supplements or sunshine. We could send our children back to school or college. We could open more businesses and allow larger gatherings. We would have reduced the burden on our healthcare system.
And why aren’t we doing this yet? It’s because certain few persons are the gatekeepers of information and truth. If they don’t proclaim it, too few persons accept it as true. The pandemic is highlighting a problem in our society with information and its evaluation and dissemination.
The Second Wave
This next point is EXTREMELY Important. The other human coronaviruses, the ones that cause colds, have all been proven to be seasonal [20, 21, 22]. Covid-19 itself has been shown by multiple studies to be seasonal [23, 24]. And the main reason for seasonality is low levels of vitamin D in winter months. If we do not undertake a vitamin D Supplements or Sunshine program soon, it will be too late to avert the Second Wave of Covid-19 cases and deaths. Monthly deaths in the U.S. could reach over 300,000 deaths per month. And the monthly case rate will overwhelm the healthcare system.

Vitamin D commentary
25. Grant, William B., et al. “Evidence that vitamin D supplementation could reduce risk of influenza and COVID-19 infections and deaths.” Nutrients 12.4 (2020): 988. Study Link
— “To reduce the risk of infection, it is recommended that people at risk of influenza and/or COVID-19 consider taking 10,000 IU/d of vitamin D3 for a few weeks to rapidly raise 25(OH)D concentrations, followed by 5000 IU/d…. For treatment of people who become infected with COVID-19, higher vitamin D3 doses might be useful.”
26. Garland, Cedric F., et al. “Vitamin D supplement doses and serum 25-hydroxyvitamin D in the range associated with cancer prevention.” Anticancer research 31.2 (2011): 607-611. Study Link
— “Results: Serum 25(OH)D rose as a function of self-reported vitamin D supplement ingestion in a curvilinear fashion, with no intakes of 10,000 IU/d or lower producing 25(OH)D values above the lower-bound of the zone of potential toxicity (200 ng/ml). Unsupplemented all-source input was estimated at 3,300 IU/d. The supplemental dose ensuring that 97.5% of this population achieved a serum 25(OH)D of at least 40 ng/ml was 9,600 IU/d. Conclusion: Universal intake of up to 40,000 IU vitamin D per day is unlikely to result in vitamin D toxicity.”
