In May 2020, just two months after shut down, British researchers found a link between Vitamin D levels and COVID-19 infections.
In October 2020, Spanish researchers found Vitamin D deficiency in 82.2% of hospitalized COVID-19 cases vs. only 47.2% of the general population. They noted that Spain, which has a high prevalence of Vitamin D deficiency, had “reached very high rates of SARS-CoV-2 infection and lethality.”
In July 2021, Italian researchers performed a large, population-based study and found that supplementing patients with Vitamin D3 so they achieved normal serum levels was associated with better COVID-19 outcomes.
In August 2021, researchers in India found that “Vitamin D status appears to be strongly associated with COVID-19 clinical severity. After COVID-19 confirmation, Vitamin D level should be measured in all patients and curative plus preventive therapy should be initiated.”
In February 2022, Israeli researchers published a study showing that COVID-19 “patients with vitamin D deficiency (less than 20 ng/mL) were 14 times more likely to have severe or critical case of COVID than those with more than 40 ng/mL. Strikingly, mortality among patients with sufficient vitamin D levels was 2.3%, in contrast to 25.6% in the vitamin D deficient group.”
In March 2022, Irish researchers reported that “the collective literature supports a causal association between low vitamin D status, SARS-CoV-2 infection, and severe COVID-19 (respiratory failure, requirement for ventilation and mortality). A biologically plausible rationale exists for these findings, given vitamin D’s role in immune regulation.”
In March 2022, researchers in Indonesia did a meta-analysis of 11 Vitamin D studies with 22,265 Covid‐19 patients. They found that Vitamin D supplementation was associated with lower rates of ICU admission, ventilator use, and mortality.
In June 2022, Spanish researchers published the results of a study that showed high doses of vitamin D3 during hospitalization for COVID-19 appeared to speed recovery.
In January 2011, researchers at U-Penn reported that the prevalence of vitamin D deficiency in the U.S. population was 41.6%, but 69.2% in Hispanics and 82.1% in Blacks. It was also more common in the obese and those with poor health. Gee … it sounds like the same people who get the ‘rona more often and more severely.
Keep in mind that this study was published nearly a decade before the pandemic hit. Conclusion: “Given that vitamin D deficiency is linked to some of the important risk factors of leading causes of death in the United States, it is important that health professionals are aware of this connection and offer dietary and other intervention strategies to correct vitamin D deficiency, especially in minority groups.”
I’ve been following the ‘rona news since February 2020 and I don’t remember seeing any calls for the peoples of the world to boost their Vitamin D supplementation or for doctors to test it. My doctor does mine, because I ask for it. But he told me just last month that they still don’t routinely include Vitamin D in blood panels. But they sure do make sure to recommend you get the jab.

There’s a reason why covid death rates were low in Florida (The Sunshine State), despite its large elderly population.
