Vitamin D – But Not Calcium – Lowers Risk Of Stress Fracture Among Young Girls

A seven-year U.S. study of preadolescent and adolescent girls has discovered a link between vitamin D intake levels and a lower risk of developing stress fractures, especially among girls active in high-impact activities. The researchers found no lessening of stress fracture risk linked with calcium intake, however, despite that fact that consumption of calcium and calcium-rich dairy products is routinely recommended for optimal bone health. They also noted that their findings support the Institute of Medicine's recent increase in the recommended dietary allowance for vitamin D for adolescents from 400 IU/d to 600 IU/d.
