25-Hydroxyvitamin D and functional outcomes in adolescents

Abstract

Vitamin D is essential for bone growth and development in children and adolescents. Adolescence is a crucial phase in bone development. Cross-sectional studies have shown a relation between vitamin D status and bone mineral density in adolescents. Long-term supplementation studies have supported the importance of vitamin D for bone health in adolescence. However, we need more studies on the optimal serum 25-hydroxyvitamin D concentration and the optimal vitamin D dosage for bone health in this age group. In addition, we need to evaluate the best way to increase vitamin D status in the general public from a public health point of view. © 2008 American Society for Nutrition.
