Abstract: The role of vitamin D in maintaining a healthy cardiovascular (CV) and the renal system
has received increasing attention. Low vitamin D levels are associated with the incidence of hypertension,
cardiac remodeling, and chronic congestive heart failure. Low vitamin D levels also influence
renal disease progression and albuminuria deterioration. Moreover, recent research indicates
that vitamin D deficiency can be a potential risk factor for coronavirus disease-19 (COVID-19) infection
and poorer outcomes. Data are inconclusive as to whether supplementation with vitamin D
agents reduces CV disease risk or COVID-19 severity. Conversely, in patients with kidney disease,
vitamin D supplementation is associated with an improvement in kidney function and albuminuria.
This narrative review considers recent data on the effects of vitamin D on the CV and renal system,
as well as its possible role regarding COVID-19 complications.
