Does Treatment of Hypovitaminosis D Increase Calcium Absorption?

University of Wisconsin, Madison·interventional·Posted Dec 28, 2007·Updated Jul 24, 2023

In Brief

A Phase 4 clinical trial evaluating Vitamin D for Osteoporosis and 5 related conditions. Completed, enrolled 19 participants across 1 site.

Detailed Summary

The purpose is to perform a one-year study designed to assess whether treatment of hypovitaminosis D increases intestinal absorption of calcium, subsequent retention of calcium within bone, decreases bone turnover, and favorably impacts upon skeletal muscle mass, functional status, measures of physical function and quality of life. I hypothesize that treatment of hypovitaminosis D results in improved intestinal calcium absorption, greater retention of calcium within the bone reservoir and improved physical function, quality of life and muscle mass.
