Official title
Efficacy of a Once Daily Calcium and Vitamin D Fortified Food Product to Improve Bone Microarchitecture in Response to Army Basic Combat Training
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The primary objective of this randomized, double-blind, placebo controlled trial is to determine the efficacy of a once per day calcium (1000mg) and vitamin D (1000IU) fortified food product on bone turnover markers, including parathyroid hormone (PTH) and microarchitecture during Army basic military training (BCT). The investigators hypothesize that consumption of a once daily calcium and vitamin D fortified food product will stabilize PTH and contribute to improved bone microarchitecture compared to placebo. The results will determine the efficacy of daily supplementation with calcium and vitamin D on bone turnover markers as well as provide novel data regarding microarchitectural changes during BCT as assessed by high resolution peripheral computed tomography (HRpQCT) scanning.
