Vitamin D3 plays an essential role in the growth, development, and overall health of infants and children. It supports calcium absorption, bone mineralization, muscle function, and immune system regulation.^[1] Vitamin D also contributes to brain development, metabolic functions, and the maintenance of intestinal barrier integrity. However, vitamin D deficiency remains a significant concern in the pediatric population, particularly among newborns, exclusively breastfed infants, and children with limited dietary intake or underlying medical conditions. Deficiency can lead to impaired growth, muscle weakness, rickets, and disturbances in calcium homeostasis, while also potentially influencing immune function and susceptibility to infections. Early recognition through appropriate clinical assessment and laboratory evaluation is important for timely intervention. Adequate dietary intake, appropriate sunlight exposure, and recommended supplementation can help maintain vitamin D status during childhood. Ensuring the quality, stability, and appropriate dosage of vitamin D3 supplements is equally important for supporting healthy growth and long-term well-being.^[2]
