- More than 100 doctors, scientists and leading authorities have signed an open letter calling for increased use of vitamin D in the fight against COVID-19
- The letter recommends taking enough vitamin D to achieve a blood level of at least 30 ng/mL (75 nmol/L). They also urge testing of all hospitalized COVID-19 patients and adding vitamin D to the treatment protocol for any patient whose level is below 30 ng/mL
- The Irish Covit-D Consortium is also calling for greater use of vitamin D against COVID-19, citing evidence showing it can lower the risk of death from COVID-19 in the elderly by as much as 700%
- Research shows giving critically ill COVID-19 patients high doses of vitamin D significantly reduced the number of days they had to spend in the ICU. They were also less likely to need ventilation
- Another recent study found high-dose vitamin D supplementation sped up viral clearance; 62.5% of participants in the intervention group became SARS-CoV-2 RNA negative within 21 days, compared to just 20.8% of controls who did not receive vitamin D
In recent weeks and months, there’s been an upshot of studies1 demonstrating the benefits of vitamin D against COVID-19. The evidence is so compelling, more than 100 doctors, scientists and leading authorities have signed an open letter2 calling for increased use of vitamin D in the fight against COVID-19.
“Research shows low vitamin D levels almost certainly promote COVID-19 infections, hospitalizations, and deaths. Given its safety, we call for immediate widespread increased vitamin D intakes,” the letter states, adding:3 “Vitamin D modulates thousands of genes and many aspects of immune function, both innate and adaptive. The scientific evidence shows that:
•Higher vitamin D blood levels are associated with lower rates of SARS-CoV-2 infection. Higher D levels are associated with lower risk of a severe case (hospitalization, ICU, or death).
•Intervention studies (including RCTs) indicate that vitamin D can be a very effective treatment. Many papers reveal several biological mechanisms by which vitamin D influences COVID-19.
•Causal inference modelling, Hill’s criteria, the intervention studies & the biological mechanisms indicate that vitamin D’s influence on COVID-19 is very likely causal, not just correlation.”
The letter recommends taking enough vitamin D to achieve a blood level of at least 30 ng/mL (75 nmol/L). They also urge testing of all hospitalized COVID-19 patients and adding vitamin D to the treatment protocol for any patient whose level is below 30 ng/mL. Many other doctors are also urging government health agencies to get onboard with vitamin D recommendations. As reported by NL Times:4
“‘There is a growing consensus in the scientific world about the important role of vitamin D,’ says Manfred Eggersdorfer, professor of Healthy Aging at the University Medical Center Groningen. He argues that ‘it can reduce the chance that you will get corona and the infection can last shorter.’
The wait-and-see attitude adopted by governments does not sit well in the scientific community. Professor of immunology at Wageningen University, Huub Savelkoul, called the attitude ‘frustrating.’
He states that ‘there are more and more studies showing the benefit of vitamin D. I think it is a kind of arrogance that the government wants to wait for a meta-study first. It seems as if we don’t care that people come to the hospital and die in the meantime. You have to be careful with that comment, but that’s where my frustration lies.'”
Vitamin D Optimization Is Powerful Prevention
In a December 23, 2020, Fox News interview5,6 (above), Dr. Peter Osborne with the Origins Nutrition Center stated that the most recent studies suggest 9 out of 10 COVID-19 deaths could have been prevented had people had adequate vitamin D levels.
While I suspect this might be an overestimation, there’s no doubt in my mind that optimizing vitamin D levels among the general population would significantly lower COVID-19 incidence and death.
“At the East Virginia School of Medicine there’s a COVID protocol that includes Vitamin D,” Osborne said. “So, if you’re hospitalized for COVID, they’re automatically putting you on between 20,000 and 60,000 units of vitamin D. This is part of their standard of care protocol in that hospital system.”…
