Abstract: In recent years, our comprehension of the function of vitamin D has significantly
evolved. The ubiquitous presence of the vitamin D receptor (Vitamin D Receptor- VDR) in the body
has led to its redefinition from a steroidal hormone primarily involved in skeletal functions to a
hormone with pleiotropic effects, exerting its influence on the circulatory, nervous, and immune
systems. This has prompted investigations into its potential use in preventing and treating chronic
metabolic disorders, cardiovascular diseases, infections, and allergic and autoimmune diseases. This
comprehensive review explores the various aspects of vitamin D, including its sources, synthesis,
functions, and its impact on different physiological systems. It delves into the epidemiology of vitamin
D deficiency, highlighting its occurrence among various age demographics and geographic
regions. The impact of vitamin D on the immune system is also explored, elucidating its immunomodulatory
and anti-inflammatory properties, particularly in the context of respiratory infections.
The review discusses emerging evidence concerning the potential advantages of vitamin D in respiratory
diseases, pediatric asthma and atopic dermatitis. It also addresses vitamin D supplementation
recommendations for various pediatric populations, including term and preterm infants. The growing
concern regarding the global health impacts of insufficient vitamin D levels necessitates further
research to bridge gaps in knowledge, particularly in enhancing screening, prevention, and approaches
to address vitamin D deficiency from birth onwards. In summary, this comprehensive
overview underscores the vital role of vitamin D, highlighting the significance of understanding its
multifaceted functions and the need for tailored supplementation strategies, especially in vulnerable
populations.
