Scientists from Boston University School of Medicine have found that patients with coronavirus with normal levels of vitamin D in the blood have a lower number of severe cases and deaths than those who are deficient. The research results are published in the journal PLOS ONE.
The study authors found that patients over 40 years of age with sufficient vitamin D levels were 51.5% less likely to die from infection than those with vitamin D deficiency.
“This study provides direct evidence that vitamin D sufficiency can prevent complications, including cytokine storms, and ultimately death from COVID-19,” said study leader Dr. Michael Holick.
Holick previously found that with enough vitamin D in the blood, the risk of COVID-19 infection is reduced by 54%.
At the same time, vitamin D helps to fight not only coronavirus but also other viruses that cause upper respiratory tract diseases, the scientist added.
In total, since the beginning of the pandemic, more than 32.4 million cases have been registered in the world, more than 985 thousand patients have died.
