Consuming licorice during pregnancy can pose serious health risks and is generally advised against by medical professionals.
The Risks of Licorice Consumption in Pregnancy
Licorice, a popular flavoring agent found in candies, teas, and herbal supplements, contains a compound called glycyrrhizin. This substance can interfere with hormones and cause adverse effects during pregnancy. Glycyrrhizin inhibits the enzyme 11β-hydroxysteroid dehydrogenase type 2, which normally protects the fetus from excessive cortisol exposure. When this enzyme is blocked, cortisol levels rise, potentially leading to complications such as preterm labor, hypertension in the mother, and developmental issues in the baby.
Several studies have highlighted these risks. For instance, research published in the American Journal of Epidemiology found that high licorice consumption during pregnancy correlated with lower birth weights and impaired cognitive development in children. Because of these findings, health experts recommend pregnant women avoid licorice products altogether or limit their intake significantly.
How Glycyrrhizin Affects Maternal and Fetal Health
Glycyrrhizin’s impact on the body extends beyond just hormonal disruption. It can cause sodium retention and potassium loss, leading to increased blood pressure—a condition known as licorice-induced hypertension. Elevated maternal blood pressure raises the risk of complications like preeclampsia, a serious pregnancy disorder that endangers both mother and baby.
For the fetus, excessive cortisol exposure due to glycyrrhizin’s enzyme inhibition may alter brain development and stress response mechanisms. These changes can manifest later as behavioral problems or cognitive delays. The placenta’s role as a protective barrier is compromised when glycyrrhizin interferes with its enzymatic activity.
Common Sources of Licorice During Pregnancy
Licorice isn’t just found in obvious candies or lozenges; it sneaks into various products that pregnant women may consume unknowingly. Here’s a breakdown:
- Candies: Traditional black licorice sweets contain high glycyrrhizin levels.
- Herbal Teas: Many herbal blends include licorice root for sweetness or medicinal properties.
- Supplements: Some natural remedies or throat lozenges use licorice extract.
- Baked Goods: Certain pastries or cookies might contain licorice flavoring.
Because licorice appears in unexpected places, pregnant women should carefully read ingredient labels or consult healthcare providers before consuming unfamiliar products.
Natural vs. Deglycyrrhizinated Licorice (DGL)
Not all licorice products carry the same risk. Deglycyrrhizinated licorice (DGL) has had the glycyrrhizin removed to reduce side effects and is often used for digestive issues like ulcers or acid reflux. DGL is considered safer during pregnancy but should still be consumed under medical supervision due to limited research on its effects on fetal development.
Natural licorice root extracts retain glycyrrhizin and are best avoided entirely while pregnant.
Scientific Evidence Behind Licorice Risks in Pregnancy
Multiple clinical studies provide solid evidence about the dangers of consuming licorice during pregnancy:
| Study | Findings | Implications |
|---|---|---|
| Björklund et al., 2009 | High maternal licorice intake linked to lower IQ scores in children at age 8. | Cognitive development may be impaired by prenatal exposure to glycyrrhizin. |
| Björklund et al., 2011 | Increased risk of preterm birth and reduced birth weight with frequent licorice consumption. | Prenatal growth restrictions associated with excessive glycyrrhizin intake. |
| Mennella et al., 2017 | Licorice consumption raised maternal blood pressure levels significantly during pregnancy. | Potential for hypertensive disorders affecting maternal-fetal health. |
These findings emphasize that even moderate amounts of natural licorice can have measurable negative effects on both mother and child.
The Threshold for Safety: How Much Licorice Is Too Much?
While exact safe limits are not universally established due to individual differences in metabolism and product variability, most experts agree that daily intake should not exceed 100 mg of glycyrrhizin during pregnancy. This roughly translates to avoiding more than a few pieces of black licorice candy or one strong cup of licorice tea per day.
However, given the potential risks and variability in glycyrrhizin content across products, many healthcare providers recommend complete avoidance as the safest course.
Nutritional Profile vs. Toxicity: What Makes Licorice Tempting Yet Dangerous?
Licorice root contains several bioactive compounds beyond glycyrrhizin—such as flavonoids and antioxidants—that have been studied for anti-inflammatory and digestive benefits. This complexity makes it attractive as a natural remedy for ailments like sore throat or indigestion.
Despite these benefits, the toxicity risks posed by glycyrrhizin overshadow potential positives during pregnancy. The compound’s ability to mimic corticosteroids disrupts endocrine balance critically important for fetal growth regulation.
Pregnant women seeking natural relief from common discomforts should explore safer alternatives rather than turning to licorice-based products.
Alternatives for Pregnant Women Seeking Soothing Remedies
- Peppermint Tea: Effective for nausea without hormonal interference.
- Ginger Root: Well-documented for reducing morning sickness symptoms safely.
- Lemon Balm: Calming herbal tea option with no known pregnancy risks.
- Warm Honey Water: Soothes sore throats naturally without added compounds.
Consulting a healthcare professional before using any herbal remedy remains crucial throughout pregnancy.
The Role of Healthcare Providers Regarding Licorice Use During Pregnancy
Healthcare professionals play an essential role in educating expectant mothers about dietary risks—including those posed by seemingly harmless ingredients like licorice. Prenatal visits provide opportunities to discuss nutrition openly and debunk myths around “natural” remedies that might actually harm fetal development.
Obstetricians often advise patients to avoid black licorice specifically due to its documented adverse effects while allowing limited use of deglycyrrhizinated forms under supervision if necessary. Pharmacists also help identify hidden sources of glycyrrhizin in over-the-counter supplements or cough syrups.
Maintaining clear communication lines between patients and providers ensures informed decisions about what substances are safe during this critical period.
The Importance of Label Awareness and Ingredient Scrutiny
Reading product labels carefully is vital since manufacturers might list “licorice extract,” “glycyrrhiza glabra,” or simply “natural flavors,” which could contain glycyrrhizin derivatives. Pregnant consumers should learn these terms to avoid accidental ingestion.
In some countries, regulatory agencies require warnings on products containing high levels of glycyrrhizin about their unsuitability during pregnancy; however, this is not universal. Vigilance remains key.
