In a groundbreaking exploration into the intricate relationship between micronutrient intake and adolescent skeletal health, recent research has shed new light on the role of vitamin B12 in bone mineral density (BMD). While vitamin B12 is widely recognized for its critical influence on neurological function and hematopoiesis, its impact on bone physiology—especially among adolescents during their peak bone acquisition phase—has remained largely ambiguous. The necessity of clarifying this association is underscored by the rising prevalence of adolescent bone health concerns and the enduring quest to optimize
