Evaluation of Calcium and Vitamin D Supplementation During Marine Corps Training

Completed · Not applicable · Has a placebo group

Conditions studied: Nutrition Status, Bone Health

In brief

The primary objective of this randomized, double-blind, placebo-controlled trial is to determine the efficacy and effectiveness of Ca and vitamin D supplementation provided daily throughout Marine Corps recruit training on maintenance of PTH and indices of bone strength in Marine Corps recruits. The investigators hypothesize that Ca+D will prevent elevations in PTH and result in greater increases in indices of bone strength compared to placebo.
