The Effects of Vitamin D & COVID-19

Vitamin D is produced in the skin from UVB sunlight exposure and is transported to the liver and then the kidneys where it is changed into an active hormone that increases calcium transport from food in the gut and ensures calcium is adequate to keep the skeleton strong and free of osteoporosis.

But Vitamin D can also support the immune system through a number of immune pathways involved in fighting SARS2COV. Many recent studies confirm the pivotal role of vitamin D in viral infections.

This study shows that, counter intuitively, countries at lower latitude and typically sunny countries, such as Spain and Northern Italy, had low concentrations of vitamin D and high rates of vitamin D deficiency. These countries also experienced the highest infection and death rates in Europe.

The researchers propose that, whereas optimizing Vitamin D levels will certainly benefit bone and muscle health, the data suggests that it is also likely to reduce serious COVID-19 complications. This may be because Vitamin D is important in regulation and suppression of the inflammatory cytokine response, which causes the severe consequences of COVID-19 an acute respiratory distress syndrome associated with ventilation and death.

one study it was found that 100% of ICU COVID-19 patients less than 75 years old had vitamin D insufficiency.

another study out of 55 patients with higher blood serum levels of vitamin D metabolite (more than 30ng/ml 25-hydroxycholecalciferol), 47 had mild symptoms, 4 had “ordinary” symptoms, 2 had severe symptoms and 2 had critical symptoms. Of the 157 patients with lower vitamin D (less than 30ng/ml 25-hydroxycholecalciferol), 2 had mild symptoms, 55 ordinary symptoms, 54 severe symptoms and 46 critical symptoms.

a third study researchers found that across European countries, there was a strong association between Vitamin D levels and per capita COVID-19 cases and mortality.

Taking a vitamin D supplement, especially if you're vitamin D deficient can particularly reduce respiratory infections.

Recommended dosage is between 600 IU to 2,000 IU per day.
