The Great Debate: Can Vitamin D Combat COVID-19?

There’s no denying the ‘D’ in Covid-19. New studies have shown there's a link between vitamin

D and rapid recovery from the disease. It may seem like stocking up on the sunshine vitamin

warrants a free pass from catching and fighting against SARS-CoV-2. But before you rush to

hoard vitamin D supplements like toilet paper, experts warn Covid is stealthy in its attack, and

isn’t your everyday respiratory virus that can be easily triumphed.

From regulating immune responses to controlling inflammation, experts have hailed the benefits

of vitamin D, long before the Covid-19 connection.

Currently, an increasing body of evidence supports the benefits with respect to the virus. It has

been found that having sufficient levels of vitamin D improves how the immune system handles

the disease.

Vitamin D toughens our immune system to fight infections. Its inflammatory powers include

regulating immune responses to ward off acute inflammation from our bodies. Critical for

maintaining bone and muscle health, as well as preventing cancers, type 2 diabetes, the vitamin

provides ample benefits for sustaining life.

Several reports suggest that a lack of the fat soluble vitamin causes increased vulnerability to

catching the virus, weakening an individual's ability to recover from Covid-19.

A study published in the Irish Medical Journal reveals countries with high mortality rates from

Covid-19, such as the United Kingdom, Italy, Spain, had patients with low vitamin D levels. The

report claims countries such as Finland, Norway, Denmark, Sweden and Finland had higher

vitamin D levels in patients, correlating with reduced Covid-19 outcomes.

Acute inflammation has been a common theme in severe COVID-19 cases. At this point,

researchers have observed a correlation between low vitamin D levels and poor outcome in

fighting the virus.

Reports suggest individuals with low levels of Vitamin D experience more severe symptoms

from the respiratory virus. Patients are also more likely to be admitted to ICU and are 12 times

more likely to face death.

However a report from the journal of BMJ Nutrition, Prevention & Health reveals vitamin D is not

a ‘magic bullet’ for reducing the impact of the disease.

The study states this link requires further examination. It found insufficient evidence of high

vitamin D levels in the treatment and prevention of the virus, as there are many biological and

environmental variables to consider with positive Covid-19 outcomes.

It also noted that disparities within healthcare and government systems within different countries

impact a nation’s ability to halt the spread.

Vitamin D can’t produce the same effect as social distancing, disinfection and vaccine. Rather,

the vitamin defends the immune system, increasing the likelihood of positive Covid-19


The daily recommendation of vitamin D is 800 IU. Sound nutrition and awareness of wellbeing

promote stronger biological and physiological systems, and processes, enabling humans to

better resist infections.

In light of the pandemic, there is sure to be sunlight at the end of this long and dark road to

global recovery. There’s no better time than now to boost our immunity.
