Efficacy and Adverse Side Effects of Two Forms of Iron in Pregnancy (NCT06014983)
Efficacy and Adverse Side Effects of Two Forms of Iron in Prenatal Micronutrient Supplements (EASE-Iron): A Randomized Controlled Trial
🩺 Plain-English Summary (8th-Grade Level)
This two-arm, double-blind randomized clinical trial will recruit 172 generally healthy, low-risk pregnant individuals aged 19-42 years living in Vancouver, Canada. Participants will be randomized to receive one of two forms of iron (ferrous fumarate or ferrous bisglycinate) in addition to a prenatal multivitamin (without iron) daily during their pregnancy until delivery, with optional continuation until \~4 weeks postpartum for breastmilk sample collection. Blood samples will be taken at baseline (13-25 weeks gestation) and follow-up (35-37 weeks gestation) to assess how different forms of iron impact body iron stores. Stool samples will be obtained within 1 week of both baseline and follow-up visits to assess changes in gut microbiome composition. This research will inform more specific guidelines for optimal iron supplementation practices for the prevention and treatment of iron deficiency for both mother and baby.
