Vitamin D is most often recognised for its role in bone health, but low levels of the supplement have been associated with a range of cardiovascular and infectious diseases.

According to a recent study published in the Plus One journal, people suffering from vitamin D deficiency are more likely to develop severe COVID-19 infection as compared to patients who have higher levels of the vitamin.

Israeli researchers found that vitamin D helped a person's immune system fight off the virus after it was measured among 1,176 patients between April 2020 to February 2021.

The findings concluded that patients with vitamin D deficiency with less than 20 ng/mL are 14 times more likely to have a severe COVID-19 infection than those with more than 40 ng/mL.
