Study finds association between COVID-19 hospitalization and vitamin D deficiency

July 21, 2025

A new study conducted by the University of South Australia, King’s College London, and Guy’s and St Thomas’ NHS Foundation suggests a connection between COVID-19 hospitalization and vitamin D deficiency.

According to a University of South Australia release, “no association was found between low vitamin D and the risk of catching COVID-19.” Though, disease risk was connected to vitamin D levels in patients of Asian or African/Afro-Caribbean heritage.

The researchers discovered that those in the vitamin D deficiency and vitamin d insufficiency groups had a higher risk of being hospitalized from COVID-19 than those with standard levels of vitamin D. These findings were “only seen in people of Caucasian backgrounds.”
