Low vitamin D levels increase the risk of serious covid by a factor of 14
A low vitamin D level is a significant risk factor when it comes to covid. According to Israeli doctors, low vitamin D levels increase the risk of serious infection with SARS-CoV-2 by a factor of 14.

Doctors from Galilee Medical Center describe in PLoS One how they studied 253 patients they treated for covid between 2020 and 2021. The doctors had determined the vitamin D level of all study participants before they came into contact with the virus.Vitamin D levels go up and down with the seasons. The researchers adjusted for this seasonal influence. In addition, the Israelis also used statistical tricks to brush away the effect of classic factors such as age, BMI, gender and chronic diseases.
Results
The higher the vitamin D level, the smaller the risk of serious illness. Or, put the other way around, the lower the vitamin D level, the greater the risk of serious illness.

Study participants with a vitamin D level of less than 20 nanograms per milliliter [50 nanomoles per liter] were 14 times more likely to become seriously ill than study participants with a level of at least 40 nanograms per milliliter [187 nanomoles per litre].
Conclusion
"The use of historical results obtained before the COVID-19 pandemic as part of a public health survey enabled us to suggest vitamin D deficiency contributes to the causal pathway of COVID-19 mortality risk and disease severity", summarize the researchers.
"Our study warrants further studies investigating if and when vitamin D supplementation among vitamin D deficient individuals in the community impacts the outcome of an eventual COVID-19 episode."
