80% of COVID-19 Patients Are Vitamin D Deficient- Study

  • COVID-19 remains a severe threat in various countries even after ten months since the novel coronavirus outbreak. A recent study with 216 COVID-19 patients found that about 80% of the people have inadequate vitamin D levels in their blood.
  • The study also highlighted that people who had both COVID-19 and insufficient vitamin D levels also had a greater number of inflammatory markers such as D-dimer and ferritin, which have been associated with poor COVID-19 results.
  • Another study revealed that COVID-19 patients with adequate vitamin D levels in their blood had 51.5 lower risks of developing complications and dying from the disease than others.
  • Health experts have suggested that sustaining adequate vitamin D levels could help mitigate the risk of the novel coronavirus infection and support the recovery process for certain people. More research is required to support this statement.

A study has found that vitamin D deficiency may increase the risk of COVID-19. Different research has also drawn the same conclusion that more than 80 percent of people with COVID-19 have insufficient vitamin D levels in their blood. 

As part of the recent study, 216 people with COVID-19 were examined in a Spain hospital. The researchers mapped the patients to control from a different dataset.

Out of all, about 82.2 percent of people were deficient in the “sunshine vitamin.” Moreover, it was found that men have lower levels of vitamin D as compared to women.

And people who were found to be both COVID-19 positive and inadequate vitamin D levels had greater levels of inflammatory markers, including D-dimer and ferritin. These factors may have a connection with poor COVID-19 results.

It was also found that people having vitamin D deficiency had a higher incidence of cardiovascular disease and hypertension. The hospital stays for those individuals were even longer as per the study.

Health conditions like diabetes, hypertension and obesity are correlated with inadequate vitamin D levels. With these reports, it seems like people with low vitamin D levels could have more severe COVID-19.

Vitamin D Levels And COVID-19 Recovery

Apart from the connection between low levels of vitamin D and the risk of COVID-19, scientists are also investigating how it could safeguard people or help them recover better. 

One way to confirm this is to detect and treat vitamin D deficiency in people at high risk, such as people with some existing illnesses, older adults, and people in nursing homes. A study found that these categories of people can be treated with vitamin D.  

Healthcare providers should recommend vitamin D for COVID-19 patients who have low vitamin D levels in their blood since it may produce advantageous impacts on both the musculoskeletal and the immune systems.


How Can You Protect Yourself From COVID-19?

In the United States, it was found that many people were having low levels of vitamin D. So, do you need to keep a check on your vitamin D levels? Does taking a vitamin D supplement enough to protect yourself or at least alleviate your risk for COVID-19?

Not everyone needs to get their vitamin D levels checked, according to a scientific study. If you have fat malabsorption syndrome, have any other medical ailment, or are obese, it’s reasonable that you keep tabs on your vitamin D levels. 

Have a glimpse at the recommended vitamin D intake –

  • Infants: 400 – 1,000 IUs per day
  • Children: 600 – 1,000 IUs per day
  • Adults: 600 – 2,000 IUs per day

Remember, the recommended intake also relies upon your current levels and if you’re trying to improve them. The study suggests that obese people need to have 2 – 3 times more vitamin D than others.

If your vitamin D levels are low, taking a supplement would be beneficial. But make sure not to take any supplements without consulting a healthcare specialist.

There’s no harm for COVID-19 patients to increase vitamin D intake as long as they don’t have a rare disorder like sarcoidosis and other granulomatous disorders.

The Bottom Line

More research is required better to comprehend the link between vitamin D and COVID-19. Scientists are continuously working to find more evidence on the same and on whether taking vitamin D with the vaccine would improve the vaccine’s effectiveness.
