Vitamin D Helps Fight Against Viruses Like Coronavirus

Find out how getting the right vitamins can help boost your immune system.

30 Mar, 2020




We’re moving indoors.

Around the globe, we’re battening up the hatches, working from home, keeping our children home from school and practising social distancing in the fight against the spread of COVID-19 disease.
For now, this means replacing socialising outdoors and kids sports with time spent in the safety of our homes. While this presents an opportunity to simplify life and focus on family, it can also affect our levels of Vitamin D, potentially an important force against COVID-19.

Let’s shed some light on Vitamin D

Otherwise known as the sunshine vitamin, your body makes Vitamin D when skin is directly exposed to the sun (not sunshine through a window). It plays different roles, from helping the body absorb calcium for strong bones to helping the immune system fight off invading bacteria and viruses.

Vitamin D helps fight off Respiratory Tract Infections

Similar to other coronavirus-caused diseases like MERS and SARS, COVID-19 is a respiratory tract illness. Common symptoms include fever, tiredness and a dry cough, but according the World Health Organization (WHO) currently about one in six people who get COVID-19 becomes seriously ill and develops difficulty breathing.

The connection between Vitamin D and COVID19 is currently being studied. Although direct results are not available just yet, it is well known that boosting your Vitamin D levels can protect you from respiratory tract infections. Studies like the meta-analysis study published in 2017, based on 25 controlled and randomised trials (totaling 11k participants), show that Vit-D supplementation can help reduce the risk of acute respiratory tract infections, particularly for those who are Vit-D deficient.

Does your body need more Vitamin D?

Even before we were all ushered indoors, over 30% of adults in Australia had a mild, moderate or even severe Vit-D deficiency. It is estimated in the US that over 40% of the population have been D-deficient (specifically, 82% of African-American adults and 63% of Hispanic adults).

What’s in your genes? Now that we’re spending more time indoors, it is important more than ever to know your unique vitamin D needs.
