The Covid-19 pandemic is a Vitamin D deficiency problem and is easy to solve: Revised to cite a new double-blind randomized study.

In this paper, I argue that the COVID-19 pandemic that has ravaged the world’s healthcare systems and economies is actually a Vitamin D deficiency problem with an unbelievably effective solution that costs a few cents a day per person but saves lives and trillions of dollars, with zero adverse side effects. Until people worldwide raise their serum Vitamin D levels to 30 ng/mL (75 nmol/L) and above—COVID-19 and other diseases caused by viruses will continue to wreak havoc on health and economies. Remarkably, fighting viruses is only the tip of the iceberg of the health problems that high doses of Vitamin D can solve. One way to verify these properties of high doses of Vitamin D for yourself is to talk to someone that you trust who takes more than 5,000 IU of Vitamin D per day. That trusted someone can be a friend, family member, co-worker, someone from your place of worship, or someone from a social network you trust. A recent double-blind randomized study now shows that high doses of Vitamin D are also very effective in treating patients who have already been infected by the virus. Finally, it remains to be proven that what is observed as the effectiveness of a vaccine against the virus is not actually a Vitamin D effect.
