OBJECTIVE: In 2019, an infection provoked by SARS-CoV-2 virus arose in Wuhan, China. Currently, there is still no definite and efficacious therapy for SARS-CoV-2 infection. Moreover, our understanding of the physiopathology of the infection, and risk elements for severity and mortality, is incomplete.

PATIENTS AND METHODS: One largely neglected element that could affect prognosis of SARS-CoV-2 infection is the vitamin status of population. The purpose of this review is to evaluate whether a vitamin insufficiency could provoke an augmented risk of SARS-CoV-2 infection or the appearance of major complications. In particular, we evaluated the presence of studies related to the state and effects of vitamin D, C, B, and A in subjects with SARS-CoV-2 disease.

RESULTS: Although, actually, the interest in a possible use for vitamin supplementation in SARS-CoV-2 patients is essentially based on indirect data, we tried to examine the evidence about a favorable effect of vitamin supplementation in the therapy of the infection and its complications.

CONCLUSIONS: Supplements with vitamin A, B, C, D, and E could represent an inexpensive and sufficiently safe approach, and a useful therapeutic complement. However, solid clinical research data are expected to support such claim.
