Vitamin A

COVID-19

Retinol

Immune function

This review explores the relationship between vitamin A levels and COVID-19 severity. Analysis of seven observational studies suggests that low retinol levels are associated with worse clinical outcomes, including increased risk of hospitalization, respiratory distress, and mortality. The findings support the potential role of vitamin A in immune function and recovery from COVID-19, though further clinical trials are needed to confirm causality.
