Israeli population-based study supports research showing that vitamin D supplements could help people avoid serious respiratory effects of Covid-19.

A low level of vitamin D in blood plasma appears to be an independent risk factor for Covid-19 infection and hospitalization, say scientists from Israeli HMO Leumit Health Services and the Azrieli Faculty of Medicine of Bar-Ilan University. The researchers came to their conclusion using real-world data and an Israeli cohort of 782 Covid-19 positive patients and 7,025 Covid-19 negative patients.

The scientists’ research follows a few worldwide studies that have shown the pronounced impact of vitamin D metabolites on the immune system response and on the development of Covid-19 infection by the novel SARS CoV-2 coronavirus.

The amount of vitamin D required should be “personalized and take into account patients’ age, gender, race and ethnicity, nutritional status and health condition.”

The team was surprised to discover that “chronic medical conditions, like dementia, cardiovascular disease and chronic lung disease that were considered to be very risky in previous studies, were not found as increasing the rate of infection in our study.”

Presently this joint Israeli research team is planning to evaluate factors associated with Covid-19 mortality in Israel.
