Vitamin D and COVID-19

Laurie Mellor – Managing Partner, Chief Executive Officer & Financial Officer | Thermal Proximity Systems


There is mounting evidence that vitamin D has a positive effect in reducing the spread and transmission of COVID-19. In addition, patients who had contracted COVID-19 were less likely to be admitted to the intensive care unit if their vitamin D levels were within acceptable norms.


Essentially, patients who are deficient in vitamin D are more likely to experience serious illness, severe complications, and increased risk of death.


This information was unveiled in a cohort study of 489 patients who had their vitamin D levels measured in the year before COVID-19 testing, the relative risk of testing positive for COVID-19 was 1.77 times greater for patients with deficient vitamin D status compared with patients with likely sufficient vitamin D status, a difference that was statistically significant.


This revelation is astonishing, however, in the words of Ciro Carafa, M.D. and internal medicine specialist at Hackensack Meridian Medical Group - “Doctors and researchers are still learning a lot about the novel coronavirus as it moves through our communities, but it does appear that having sufficient levels of vitamin D in your system may offer some protection from the worst that COVID-19 has to offer.”


From a laypersons perspective it makes a ton of sense – vitamin D is essential for good health. Vitamin D deficiency is one of the most common nutrient deficiencies in the world.

In fact, up to 42% of the adult population in the US have low vitamin D levels, which can cause health problems as it is particularly important for bone health and immune system function.


Certainly, we’re all hopeful that the vaccines will do their job and rid us of this terrible disease, however, it will be several months until enough of us are protected to turn things around so we can all return to normal.


So, in the meantime it is important to be vigilant and wear a mask, keep your distance from others, wash your hands and stay home if you have an elevated body temperature.

Lastly, don’t leave the house without taking your 20 micrograms (800 IU) of vitamin D to add one more level of protection.


We here at Thermal Proximity Systems wish you well in the New Year and we look forward to helping organizations return safely to work, learn and play.
