In recent years, Vitamin D has emerged as a focal point of biomedical research owing to its proposed involvement in the pathogenesis of numerous conditions, including cancers, autoimmune diseases, hypertension, and infectious diseases. Insufficient awareness of the fact that controlled sunlight exposure is the primary source of endogenous Vitamin D production remains the leading cause of its deficiency. The assessment of Vitamin D status in clinical practice relies primarily on the measurement of serum 25-hydroxyvitamin D [25(OH)D], which is widely recognized as the most accurate and informative biomarker. Complementary laboratory findings, including hypocalcemia, hypophosphatemia, and elevated levels of alkaline phosphatase, can further support the diagnosis of Vitamin D deficiency, reflecting its impact on mineral metabolism and skeletal health. The widespread prevalence of Vitamin D deficiency, coupled with its involvement in the pathogenesis of numerous disorders, highlights the necessity for broad public health initiatives and educational programs directed at both healthcare providers and the general population.
