Summary
This article presents a double-blind randomized controlled trial investigating the role of vitamin D supplementation in preventing acute respiratory infections (ARIs). The study addresses the significant global public health challenge of ARIs, which account for substantial morbidity and mortality, particularly in vulnerable populations like children, the elderly, and immunocompromised individuals. The research examines whether vitamin D supplementation can reduce the incidence, severity, or duration of acute respiratory infections based on emerging evidence about vitamin D's potential role in immune function and respiratory health.

According to the World Health Organization, ARIs are responsible for nearly 20% of global deaths in children under five years of age, with a rising burden among adults, particularly those with underlying chronic diseases and compromised immunity.
In low- and middle-income countries, frequent viral and bacterial respiratory infections further strain healthcare resources and lead to significant economic losses.
Emerging evidence suggests that vitamin D, through its immunomodulatory effects, may play a crucial role in reducing susceptibility to respiratory infections and modulating disease severity.
Background: Acute respiratory infections (ARIs) remain among the most common causes of morbidity and mortality worldwide, particularly in children, the elderly, and immunocompromised individuals. Emerging evidence suggests that vitamin
