Probiotic Intervention Shows Promise in Preventing iron Deficiency During Pregnancy
Table of Contents
A clinical trial launched this month aims to determine if a specific probiotic can mitigate iron deficiency anemia, a common complication impacting approximately 18% of pregnant women even while taking prescribed iron supplements. The research, beginning September 15, 2025, seeks to proactively address declining iron levels during the crucial second trimester of pregnancy.
Iron deficiency anemia during pregnancy can have implications for both maternal and infant health. This study investigates a preventative approach, focusing on individuals with suboptimal, but not yet anemic, hemoglobin levels.The goal is to bolster iron absorption and potentially improve outcomes for both mother and child.
Study Design and Participants
The study will involve roughly 200 participants, starting between 10 and 16 weeks of gestation, and continuing until delivery. Participants will be divided into two groups: one receiving the probiotic Lactiplantibacillus plantarum 299v (LP299V) alongside their standard prenatal vitamin, and a control group receiving a placebo pill along with the prenatal vitamin. The probiotic,known to influence the gut microbiome,is hypothesized to enhance iron absorption.
Researchers are specifically targeting individuals with low hemoglobin-the iron-rich protein in red blood cells responsible for oxygen transport-but who haven’t yet been diagnosed with anemia. It’s easy to become anemic once you’re “on the border,” notably in the second trimester,

Key Study Components
The research team will analyze participants’ gut microbiomes to assess the probiotic’s impact on iron absorption. Furthermore, they will collect placental and cord blood samples at delivery to evaluate whether improved maternal iron levels translate to the baby. Neurocognitive developmental assessments will be conducted on the infants to identify any potential differences between those born to mothers who took the probiotic versus those who didn’t.
| Study Phase | Timeline | Key Activities |
|---|---|---|
| Recruitment | September - October 2025 | Enroll 200 pregnant participants |
| Intervention | October 2025 – Delivery | Probiotic/Placebo administration |
| Data Collection | At Delivery | Placenta, cord blood samples |
| Follow-up | 6-12 months post-partum | Infant neurocognitive assessments |
A prior feasibility study indicated the probiotic may also alleviate gastrointestinal discomfort frequently enough associated with iron supplements, a significant factor in medication adherence.This trial has the potential to transform prenatal care and health outcomes for hundreds of thousands of pregnant peopel and their children in the U.S. and millions worldwide,

Did You Know?
Iron deficiency is the most common nutritional deficiency worldwide, and pregnant women are particularly vulnerable due to increased iron demands.
Pro Tip:
If you are pregnant or planning to become pregnant, discuss your iron levels and supplementation options with your healthcare provider.
Will this probiotic intervention become a standard part of prenatal care? What impact could improved iron absorption have on long-term child development?
Frequently Asked Questions about Probiotics and Iron Deficiency in Pregnancy
- What is iron deficiency anemia? It’s a condition where the body doesn’t have enough iron to produce sufficient red blood cells,leading to fatigue and other health problems.
- Why are pregnant women at risk for iron deficiency? Pregnancy increases the demand for iron to support the growth of the fetus and placenta.
- What is a probiotic, and how might it help with iron absorption? A probiotic is a live microorganism that can benefit health. Lactiplantibacillus plantarum 299v (LP299V) has been shown to alter the gut microbiome, potentially enhancing iron uptake.
- What is hemoglobin, and why is it important during pregnancy? Hemoglobin is the protein in red blood cells that carries oxygen. Adequate hemoglobin levels are crucial for both maternal and fetal health.
- What are the potential benefits of this study? The study aims to determine if a probiotic can prevent iron deficiency anemia,improve maternal iron levels,and positively impact infant development.
Iron deficiency anemia has been a public health concern for decades, particularly in vulnerable populations. While iron supplementation is a common treatment, adherence can be challenging due to side effects. Emerging research suggests the gut microbiome plays a significant role in iron absorption, opening new avenues for preventative strategies. This study builds upon a growing body of evidence exploring the potential of probiotics to improve maternal and infant health outcomes.
