  • The objective of the study is to know if consumption of an iron fortified fruit juice containing micronized iron pyrophosphate, is useful to increase iron status in women predisposed to iron deficiency anemia.
  • A secondary objective is to know if consumption of this iron fortified fruit juice modifies bone remodelling.
