Licorice can potentially cause constipation due to its glycyrrhizin content, which affects electrolyte balance and slows bowel movements.
The Complex Effects of Licorice on Digestion
Licorice root has been used for centuries in traditional medicine and as a flavoring agent in candies, teas, and supplements. Its distinct sweet taste comes from glycyrrhizin, a compound far sweeter than sugar. While licorice is often praised for soothing sore throats and aiding digestion, its impact on bowel movements is less straightforward.
Some people find licorice helps ease digestive discomfort, but others report constipation after consuming it regularly. This paradox stems from how glycyrrhizin interacts with the body’s electrolyte balance—particularly sodium and potassium—and influences muscle contractions in the intestines.
The key lies in the mineralocorticoid-like effects of glycyrrhizin. It inhibits an enzyme called 11-beta-hydroxysteroid dehydrogenase type 2, which normally converts cortisol to its inactive form. When this enzyme is blocked, cortisol accumulates, mimicking aldosterone’s action that causes sodium retention and potassium loss. This imbalance can lead to water retention and muscle weakness, including the smooth muscles lining the digestive tract, potentially slowing down bowel movements.
How Glycyrrhizin Influences Bowel Function
Glycyrrhizin’s impact on electrolytes is central to understanding licorice’s effect on constipation. Potassium plays a crucial role in muscle contractions throughout the body, including the intestines. Low potassium levels (hypokalemia) cause muscles to become weak or less responsive.
When glycyrrhizin causes potassium depletion by promoting urinary excretion of this mineral, intestinal motility may decrease. Reduced motility means food and waste move more slowly through the colon, leading to harder stools and constipation.
This effect is more pronounced with excessive licorice consumption or in individuals sensitive to its compounds. For example, ingesting large amounts of licorice candy daily or taking concentrated licorice supplements can push electrolyte levels out of balance.
Who Is Most at Risk?
Certain groups face higher risks of experiencing constipation from licorice:
- People with pre-existing electrolyte imbalances: Those already low in potassium or with kidney issues may see worsened symptoms.
- Individuals on medications: Drugs like diuretics or corticosteroids can amplify potassium loss when combined with licorice.
- Elderly adults: Aging kidneys may be less efficient at correcting mineral imbalances.
- High consumers: Anyone regularly eating large quantities of licorice products.
In contrast, moderate consumption rarely causes noticeable constipation in healthy individuals.
The Dual Nature: Can Licorice Also Relieve Constipation?
Interestingly enough, not all effects of licorice are constipating. Some studies suggest that certain components in licorice—like flavonoids—have mild laxative properties by increasing bile secretion or promoting gut motility.
In herbal medicine traditions, licorice is sometimes combined with other herbs that stimulate digestion and relieve bloating or mild constipation symptoms. However, these benefits typically come from whole root extracts rather than highly processed candy forms loaded with sugar and additives.
The takeaway? Licorice’s effect on bowel function depends heavily on dosage, preparation method, individual sensitivity, and overall diet quality.
Licorice Preparations Compared
| Form | Glycyrrhizin Content | Potential Effect on Bowel |
|---|---|---|
| Natural Licorice Root Tea | Moderate (varies by brand) | Mild laxative or neutral effect depending on dose |
| Licorice Candy (Traditional) | Low to Moderate (varies) | Possible constipation if consumed excessively due to sugar + glycyrrhizin |
| DGL (Deglycyrrhizinated Licorice) Supplements | Very Low (glycyrrhizin removed) | No constipating effect; often used for digestive relief |
The Science Behind Licorice-Induced Constipation Symptoms
Clinical evidence links excessive licorice intake to symptoms like bloating, abdominal discomfort, and constipation through biochemical pathways involving cortisol metabolism and electrolyte shifts.
One study showed that consuming more than 100 mg of glycyrrhizic acid daily over several weeks could cause hypokalemia severe enough to impair muscle function—including intestinal muscles. Symptoms resolved when intake stopped or potassium was replenished.
Moreover, chronic use may lead to pseudoaldosteronism—a condition mimicking aldosterone excess—resulting in high blood pressure alongside constipation. This highlights why paying attention to dosage matters immensely.
The Role of Sugar in Licorice Candy
Traditional black licorice candies often contain high amounts of sugar alongside glycyrrhizin-rich extract. Sugar itself can influence gut health negatively by altering microbiota balance or causing dehydration if consumed excessively without adequate fluids.
Therefore, some cases of constipation blamed solely on licorice might partly stem from sugar’s dehydrating effects combined with glycyrrhizin-induced muscle sluggishness.
Naturally Managing Licorice-Related Constipation Risks
If you enjoy licorice but worry about constipation risks, here are practical tips:
- Limit intake: Keep consumption moderate—experts recommend no more than 100 mg glycyrrhizic acid daily.
- Stay hydrated: Water aids digestion and counters dehydration effects from sugar.
- Balance electrolytes: Eat potassium-rich foods like bananas, spinach, and sweet potatoes.
- Avoid mixing with certain medications: Consult your doctor if you’re on diuretics or steroids.
- Select DGL supplements: These remove glycyrrhizin while retaining other beneficial compounds.
These strategies help reduce any negative impact while still letting you enjoy licorice’s unique flavor and benefits safely.

Frequently Asked Questions
Does licorice make you constipated due to glycyrrhizin?
Yes, licorice can cause constipation because glycyrrhizin affects electrolyte balance, especially potassium levels. This can weaken intestinal muscles and slow bowel movements, leading to constipation in some individuals.
How does licorice make you constipated through its impact on digestion?
Licorice influences digestion by altering muscle contractions in the intestines. Its glycyrrhizin content can cause water retention and muscle weakness, slowing down bowel movements and potentially causing constipation.
Can consuming large amounts of licorice make you constipated?
Excessive consumption of licorice, especially candy or supplements high in glycyrrhizin, may disrupt electrolyte balance. This increases the risk of constipation by reducing intestinal motility and causing harder stools.
Who is most likely to get constipated from eating licorice?
People with existing electrolyte imbalances, kidney problems, or those taking medications like diuretics are more prone to constipation from licorice. Their bodies are more sensitive to potassium loss caused by glycyrrhizin.
Is there a way to enjoy licorice without becoming constipated?
Moderation is key. Consuming small amounts of licorice occasionally is less likely to cause constipation. Staying hydrated and maintaining a balanced diet can also help reduce the risk of digestive issues.
The Final Word – Does Licorice Make You Constipated?
Yes—licorice can make you constipated if consumed excessively due to its glycyrrhizin content affecting potassium levels and intestinal muscle function. However, moderate intake usually poses little risk for healthy individuals. The form of licorice matters too; natural root teas or deglycyrrhizinated supplements are less likely to cause constipation compared to sugary candy versions packed with glycyrrhizin.
Understanding how this sweet herb interacts with your body helps you make informed choices about enjoying it without unpleasant digestive side effects. If you notice persistent changes in bowel habits after eating licorice products regularly, consider cutting back or consulting a healthcare professional for advice tailored specifically to your needs.
