Deficiencies of iron and folic acid during pregnancy can lead to adverse outcomes for the fetus, thus supplements are recommended. Adherence to current tablet-based supplements is documented to be poor. Recently a powdered form of micronutrients has been developed which may decrease side-effects and thus improve adherence. However, before testing the efficacy of the supplement as an alternate choice for supplementation during pregnancy, the bioavailability of the iron needs to be determined. The objective of this study is to measure the relative bioavailability of iron and folic acid from a powdered supplement that can be sprinkled on semi-solid foods or beverages versus a traditional tablet supplement in pregnant women.

Condition Intervention Phase
Iron Deficiency Folic Acid Deficiency Dietary Supplement: Daminaide 995 - SuppleFem Sprinkles Dietary Supplement: Materna Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Official Title: Relative Bioavailability of Iron and Folic Acid From a New Powdered Supplement Compared to a Traditional Tablet in Pregnant Women

Further study details as provided by University of Toronto:

Primary Outcome Measures:
  • The primary outcome is a comparison of area under the curve (AUC) for change in serum iron for each intervention adjusted for diurnal variation. The use of AUC will provide a single outcome for each participant. [ Time Frame: 3 weeks ]

Secondary Outcome Measures:
  • The secondary outcome is a comparison of area under the curve (AUC) for change in serum folate for each intervention [ Time Frame: 2 weeks ]

Enrollment: 18
Study Start Date: October 2005
Study Completion Date: July 2006
Primary Completion Date: July 2006 (Final data collection date for primary outcome measure)
Intervention Details:
    Dietary Supplement: Daminaide 995 - SuppleFem Sprinkles
    The study agent SuppleFem will be a preblend manufactured by Acatris in Oakville Ontario and will be repackaged into 1 gram aliquots in white plastic Tamper Seal Vials.1 ram to be taken with test meal
    Dietary Supplement: Materna
    Materna is a pregnancy supplement available on the Canadian market and is manufactured by Wyeth. Dose is 1 tablet per day
