Calcium and Vitamin D Supplementation Decreases Incidence of Stress Fractures in Female Navy Recruits

Completed · Not applicable

Conditions studied: Stress Fracture

In brief

We conducted a double-blind, placebo-controlled randomized clinical trial of calcium and vitamin D supplementation in 5201 female Naval recruits. During 8 weeks of basic training, supplementation with 2000 mg calcium and 800 IU vitamin D/day decreased incidence of stress fracture by 25%. The hypothesis was: Supplementation with calcium 2000 mg/d and vitamin D 800 IU/d will significantly reduce the incidence of stress fractures in female Navy recruits during 8 weeks of basic training.
