Summary

The purpose of this study is to determine whether increasing levels of serum 25(OH)Vitamin D as achieved by oral supplementation higher than the current recommendations are associated with a less negative bone calcium balance in post-menopausal Swiss women.

Detailed description

In a substudy - not related to the vitamin D intervention - spot and 24 h urine samples are compared with regard to the assessment of iodine status in Swiss post-menopausal women. In an short subsequent study using five of the subjects who participated in the original trial, the effect of a 40 d-exercise program (rebounding on a trampoline) on Ca-41 excretion will be observed.
