Iron serves as a crucial mineral for all individuals due to its role in facilitating the production of hemoglobin, a protein present in red blood cells, which aids in transporting oxygen from the lungs throughout the body. Additionally, iron is instrumental in the synthesis of myoglobin, another protein that facilitates oxygen delivery to muscles.
Insufficient iron levels may lead to the development of iron-deficiency anemia, characterized by symptoms such as weakness, fatigue, and difficulty concentrating.
During pregnancy, the significance of iron escalates further. Apart from fulfilling the mother's iron requirements, there is also an increasing demand for iron to support the developing baby.
How much iron do I need during pregnancy?
During pregnancy, the requirement for iron increases beyond the usual levels. While non-pregnant adult women typically need 18 mg/day of iron, pregnant women require 27 mg/day.
There are three primary reasons for this heightened need for iron during pregnancy:
- Increased blood volume: Pregnancy leads to a larger volume of blood in the body, resulting in a higher number of red blood cells. Iron is essential for the function of red blood cells.
- Baby's iron requirements: Throughout pregnancy, the developing baby necessitates iron. In fact, iron is stored in the baby's body while in the womb, serving as a reserve for the initial six months post-birth.
- Iron requirements of the placenta: The placenta, a vital organ that forms during pregnancy, also requires iron. It serves as the conduit for nutrients to the growing baby. During pregnancy, the placenta stores iron to safeguard the baby in the event of maternal iron deficiency.
Do I need an iron supplement during pregnancy?
In the United States, it's generally advised that all pregnant women take a prenatal vitamin containing iron and maintain an iron-rich diet. The necessity for an additional iron supplement depends on individual iron levels.
However, there isn't a consensus among experts regarding the specifics of iron supplementation during pregnancy. Various organizations offer differing perspectives:
- American College of Obstetricians and Gynecologists (ACOG): ACOG recommends prenatal vitamins with iron during pregnancy, supplemented by a nutritious diet. The organization does not specify the iron dosage in the prenatal vitamin.
- World Health Organization (WHO): WHO suggests a daily iron supplement ranging from 30 to 60 mg, which can be part of the prenatal vitamin or provided separately.
- U.S. Preventive Services Task Force (USPSTF): USPSTF indicates insufficient evidence to advocate for routine iron supplementation in all pregnant women. They suggest that studies have conflicting findings regarding the necessity of routine iron supplementation for all pregnant women, including those with normal iron levels.
Despite the discrepancies in recommendations, most obstetricians will likely advise taking a prenatal vitamin with iron and consuming an iron-rich diet. It's important to review the label of your prenatal vitamin to ensure it contains iron, as not all prenatal vitamins do.
Your obstetrician will probably conduct blood tests to screen for anemia during pregnancy. If iron-deficiency anemia is detected, they may suggest adding an iron supplement to your prenatal vitamin regimen, after obtaining approval from your obstetrician.
Furthermore, increasing the dosage of your prenatal vitamin to compensate for an iron deficiency is not recommended, as this would elevate your intake of all vitamins in the prenatal, which could be hazardous.

Why is low iron in pregnancy dangerous?
Due to its pivotal role in numerous bodily functions, untreated iron deficiency can result in adverse effects for the mother, including:
- Preeclampsia
- Increased susceptibility to infections
- Organ damage attributable to oxygen deprivation
- Heart-related issues such as arrhythmias or heart failure
- Compromised immune system function
Insufficient iron intake can also lead to complications for the developing baby. Research indicates that babies who receive inadequate iron may have a higher likelihood of being born prematurely or with a low birth weight.

Differences Between Iron and Vitamin
Iron
Iron is primarily involved in the production of hemoglobin, the protein in red blood cells responsible for carrying oxygen from the lungs to tissues throughout the body. Iron also plays a role in energy metabolism and immune function.
Vitamins
Vitamins serve a variety of functions in the body, including acting as antioxidants, participating in energy production, supporting immune function, aiding in the synthesis of hormones and neurotransmitters, and contributing to bone health, among others.
Alternative to Iron
Herbal Remedies:
Some herbal remedies, such as nettle leaf and yellow dock root, are traditionally believed to support iron absorption and may be used as complementary approaches to iron supplementation. However, evidence supporting their efficacy is limited, and it's essential to consult with a healthcare professional before using herbal remedies, especially during pregnancy or if you have underlying health conditions.
What are symptoms of low iron in pregnancy?
Low iron levels may not always manifest noticeable symptoms, particularly in the early stages. However, if left unaddressed, low iron levels can progress to iron-deficiency anemia. Common signs and symptoms of iron-deficiency anemia comprise:
- Shortness of breath
- Fatigue
- Weakness
- Hair loss
- Leg cramps
Certain symptoms of low iron may overlap with typical signs of pregnancy. Nevertheless, if you experience persistent symptoms indicative of iron-deficiency anemia, it is advisable to consult your healthcare provider. They may opt to conduct a blood test to assess iron levels.
Best iron supplements during pregnancy
There is a variety of over-the-counter (OTC) iron supplements available, including:
- Ferrous gluconate
- Ferrous fumarate
- Ferrous sulfate
- Ferrous bisglycinate
No single iron supplement is inherently superior to others, but individual preferences may influence your choice. For instance, ferrous bisglycinate is reported to have fewer side effects compared to ferrous fumarate. It can also elevate iron levels comparably to ferrous fumarate but with a lower dosage, which is significant considering that side effects of iron supplements are often dose-dependent.
Other factors to consider include the form of the supplement (liquid or chewable), dietary preferences (vegan or vegetarian), and affordability. If your healthcare provider recommends an iron supplement during pregnancy, it's advisable to discuss which option suits you best.
Regardless of the supplement chosen, it's crucial to pay attention to the amount of "elemental iron" in the product. Elemental iron refers to the actual iron content that the body can absorb, which is more relevant than the total iron content. Typically, the elemental iron quantity is the smaller number on the product label. For instance, a ferrous sulfate tablet labeled as 325 mg might contain 65 mg of elemental iron.
In severe cases of iron-deficiency anemia during pregnancy or instances where oral iron intake is not feasible, intravenous iron supplementation may be necessary.
Is there such a thing as too much iron in pregnancy?
It's crucial not to take additional iron during pregnancy without consulting your healthcare provider first.
For pregnant women who do not have low iron levels, the recommended maximum intake of iron from both food and supplements combined is 45 mg per day. Exceeding this limit can lead to adverse effects, such as maternal high blood pressure or potential complications in the unborn baby's growth.
However, it's important to note that this maximum recommendation may not apply to pregnant women diagnosed with iron-deficiency anemia. In such cases, healthcare providers may suggest doses surpassing 45 mg per day. For example, the WHO recommends a dosage of 120 mg per day for pregnant women diagnosed with iron-deficiency anemia.
Always consult your healthcare provider before initiating an iron supplement regimen. If you have low iron levels, they can guide you in ensuring that you're taking a safe and appropriate dosage. Your healthcare provider's guidance is essential to safeguarding both your health and the well-being of your unborn baby.
Conclusion
The question "Can I take iron supplements while pregnant?" underscores the importance of considering individual health needs and seeking guidance from healthcare professionals. While iron supplementation is commonly recommended during pregnancy to address increased iron demands, the choice of supplement and dosage should be made in consultation with a healthcare provider. Factors such as potential side effects, form of supplement, and elemental iron content should be carefully evaluated.
While over-the-counter iron supplements are widely available, their usage should be monitored to ensure optimal health outcomes for both the mother and the developing baby. In cases of severe iron deficiency or difficulty in oral iron absorption, intravenous iron supplementation may be necessary. Ultimately, the decision to take iron supplements during pregnancy should be informed by comprehensive discussions with healthcare providers to promote maternal and fetal well-being.
