Clinical Trial Summary

The main objective of this study is to find whether supplemental vitamin d and calcium can reduce the incidence of stress fractures in recruits. These high-risk recruits undergo intensive training which elevated bone turnover, which requires adequate level of vitamin D and calcium in order to support bone health. It is hypothesized that supplemental vitamin d and calcium will decrease the occurrence of stress fractures.
