TLDR
Bolus vitamin D3 supplementation during or just before COVID-19 was associated with less severe COVID-19 in frail elderly and vitamin D3 supplementation during or just before COVID-19 was associated with better survival rate in frail elderly.
Abstract
Highlights • Vitamin D may be a central biological determinant of COVID-19 outcomes.• Bolus vitamin D3 supplementation during or just before COVID-19 was associated with less severe COVID-19 in frail elderly.• Bolus vitamin D3 supplementation during or just before COVID-19 was associated with better survival rate in frail elderly.• Randomized controlled trials are expected to firmly conclude the effect of vitamin D supplementation on COVID-19 prognosis.
