Vitamin D, Immune System & SARS-CoV-2 (COVID-19) | Mechanism of Vit D Immune Regulation & Overview

The video explores the role of vitamin D in regulating the immune system, particularly in the context of respiratory infections like COVID-19. It discusses the impact of vitamin D deficiency on susceptibility to infections and highlights research showing that vitamin D supplementation can reduce the incidence of respiratory infections. The video also explains the mechanisms by which vitamin D modulates immune responses, including the regulation of antimicrobial peptides and cytokines. Additionally, it examines the inverse correlation between vitamin D levels and COVID-19 comorbidities, emphasizing the importance of maintaining adequate vitamin D levels for immune health.
