Story at-a-glance

  • Researchers investigated the effects of Pulse D therapy — daily high-dose supplementation (60,000 IUs) of vitamin D — for eight to 10 days, in addition to standard therapy, for COVID-19 patients deficient in vitamin D
  • Vitamin D levels increased significantly in the vitamin D group — from 16 ng/ml to 89 ng/ml — while inflammatory markers significantly decreased, without any side effects
  • Vitamin D has multiple actions on the immune system, including enhancing the production of antimicrobial peptides by immune cells, reducing damaging proinflammatory cytokines and promoting the expression of anti-inflammatory cytokines
  • A growing number of studies shows that vitamin D administration significantly reduces ICU admission and death in cases of COVID-19
  • Vitamin D is inexpensive, widely available and safe; getting your blood tested — and optimizing your levels — is one of the simplest and most straightforward steps you can take to improve your health, including in relation to COVID-19
