First Posted : December 21, 2005
Last Update Posted : January 30, 2008
Objectives To evaluate the effect of increased vitamin D intake on vitamin D status, bone mass and bone turnover in young girls aged 12-13.
More specifically the effects on the following parameters will be assessed:
- Vitamin D metabolites.
- Parathyroid hormone.
- Bone turnover.
- Bone mineral accretion.
- Serum calcium and phosphate.
- Renal handling of calcium and phosphate.
