Vitamin D could be a piece of COVID-19's 'complex puzzle,' Israeli scientists say, after a new study finds a link between deficiency and severe illness

  • Low levels of vitamin D prior to catching COVID-19 were linked to worse illness, a study found.

  • Vitamin D helps bolster the immune system to tackle viruses that attack the lungs, researchers said.

  • Vitamin D is "one piece of the complex puzzle" underlying severe COVID-19, the scientists cautioned.

Israeli scientists said they found "striking" differences in the chances of getting seriously ill from COVID-19 when they compared patients who had sufficient vitamin D levels prior to contracting the disease with those who didn't.

A study published on Thursday in the research journal PLOS One found that about half of people who were vitamin D deficient before getting COVID-19 developed severe illness, compared to less than 10% of people who had sufficient levels of the vitamin in their blood.

We know vitamin D is vital for bone health, but its role in protecting against severe COVID-19 is less well established.

The latest research was the first to examine vitamin D levels in people prior to them contracting COVID-19, the study authors said.

Dr. Amiel Dror, a study author and physician at the Galilee Medical Center, said of the findings, "We found it remarkable, and striking, to see the difference in the chances of becoming a severe patient when you are lacking in vitamin D compared to when you're not," The Times of Israel reported.

The findings come from 253 people admitted to Galilee Medical Center in Nahariya, Israel, between April 7, 2020, and February 4, 2021 — a period before the highly infectious Omicron variant emerged.

Dror said the findings suggested that vitamin D helped bolster the immune system to deal with viruses that attack the respiratory system.

"This is equally relevant for Omicron as it was for previous variants," Dror said.

The research doesn't prove that vitamin D protects against COVID-19 and isn't a green light to avoid vaccines and take vitamins instead. Vaccines cut the risk of Omicron hospitalization, particularly after a booster, by up to 90%, the UK Health Security Agency said.
