BACKGROUND The role of vitamin D supplementation as a treatment for COVID-19 has been a subject of considerable discussion. A thorough understanding of the current evidence regarding the effectiveness and safety of vitamin D supplementation for COVID-19 based on randomised controlled trials is required. OBJECTIVES To assess whether vitamin D supplementation is effective and safe for the treatment of COVID-19 in comparison to an active comparator, placebo, or standard of care alone, and to… 

Does vitamin D supplementation reduce COVID-19 severity?: a systematic review

The findings of this study show that vitamin D supplementation is effective in reducing the COVID-19 severity and should be recommended as an adjuvant therapy for CO VID-19, however, more robust and larger trials are required to substantiate it further.

Vitamin D supplements, and especially calcifediol, were shown to be useful in significantly reducing ICU admissions and/or mortality in four of the studies, but not in diminishing the duration of hospitalization of COVID-19 patients.

Cochrane Review Summary on “Vitamin D Supplementation for the Treatment of COVID‐19: A Living Systematic Review”

A Cochrane living systematic review examining the effectiveness and safety of using vitamin D supplementation to treat individuals diagnosed with COVID-19 found very low-certainty evidence and mixed results among two studies for the effect of vitamin D on all-cause mortality at hospital discharge.
