Iron-fortified Flavoured Skimmed Milk With or Without Vitamin D in Iron Deficient Women

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
M Pilar Vaquero, National Research Council, Spain
ClinicalTrials.gov Identifier:
NCT01739907
First received: November 20, 2012
Last updated: June 12, 2014
Last verified: November 2012
  Purpose

Iron deficiency and vitamin D deficiencies are common in menstruating women. The present assay studied the influence of the consumption of a flavoured skimmed milk with iron (iron pyrophosphate) or with iron and vitamin D3 in iron deficient women on:

  • Iron metabolism
  • Biomarkers of bone remodelling
  • Cardiovascular risk indexes

Condition Intervention
Iron Deficiency Other: Iron fortified flavoured skimmed milk with or without vitamin D in iron deficient women

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
