Yet another piece of evidence emerges validating Vitamin D as "the immune system vitamin".
On February 3, 2022, an article was published showing that pre-infection Vitamin D deficiency is associated with increased severity of Covid-19 infection severity and mortality.
The research was done by a team out of Israel and published in the peer-reviewed journal PLOS ONE. You can click the image above to see the article.
The researchers found that in a group of 253 people hospitalized for Covid-19 infection, the group with the most severe infections was most likely to have a low Vitamin D level. 87% of those with illness categorized as "severe or critical" had levels below 20 ng/ml while only 34% of those categorized as "moderate or mild" had levels below 20 ng/ml.
Key Point:
Many experts and researchers agree that an ideal Vitamin D level is in the range of 40 - 60 ng/ml. The above mentioned study found that people with Vitamin D levels at or below 20 ng/ml were 14 times more likely to have a severe Covid-19 infection than those with a Vitamin D level at or above 40 ng/ml.
Very interesting observation from this research article. They only wanted to look at pre-infection Vitamin D levels, so they had to study people who happened to have their Vitamin D level checked before they got sick. Of 1176 people who were admitted to the hospital with Covid-19 infection, only 253 had records of a previous Vitamin D test before being admitted. This means that even though Vitamin D levels may literally mean the difference between life and death, recovery or not, only about 22% of the population had had a Vitamin D test in the years leading up to a Covid-19 infection.
Are you in the 78% that have never had their Vitamin D tested? If you have had a Vitamin D test, is your blood level in the optimal range of 40 - 60 ng/ml? Studies like this one show us that now is the time to take action.
