Natural mucosal support with quick neutralizers delivers instant and sustained comfort.
DGL vs. Antacids for Mild Heartburn Efficacy
Heartburn, a common symptom of acid reflux or gastroesophageal reflux disease (GERD), affects millions worldwide. Two popular remedies are antacids and DGL (deglycyrrhizinated licorice). This article deeply examines comparative efficacy, speed of relief, long-term effects, safety, and usage practices of these options based on latest clinical and scientific research.

Understanding Mild Heartburn
Heartburn is characterized by a burning sensation in the chest, commonly after eating or when lying down, resulting from the backflow of stomach acid into the esophagus. While severe forms may require prescription therapies, mild heartburn is frequently self-managed with lifestyle modifications and over-the-counter (OTC) remedies such as antacids and herbal supplements.
- Symptoms: Burning chest pain, sour taste, mild discomfort after meals.
- Triggers: Spicy or fatty foods, caffeine, alcohol, obesity, stress, lying down after meals.
- Incidence: Upwards of 18-27% of adults experience symptoms at least weekly.
What are Antacids?
Antacids are fast-acting, OTC medications that neutralize existing stomach acid. Common active ingredients include magnesium hydroxide, calcium carbonate, and aluminum hydroxide. They are widely adopted for immediate relief of heartburn and mild acid indigestion.
- Examples: Tums, Rolaids, Maalox, Mylanta.
- Formulations: Chewable tablets, liquids, effervescent powders.
- Typical Uses: Occasional relief for heartburn, upset stomach, or sour stomach.
Main Benefits of Antacids
- Rapid symptom relief (within minutes).
- Convenient, widely available, and inexpensive.
Limitations
- Temporary effect – symptoms often recur as acid secretion resumes.
- Overuse can result in constipation, diarrhea, or imbalances in electrolytes.
- No effect on underlying esophageal mucosal healing.
What is DGL?
DGL (Deglycyrrhizinated Licorice) is an extract of licorice root (Glycyrrhiza glabra), processed to remove glycyrrhizin to minimize the risk of hypertension and fluid retention commonly associated with whole licorice. DGL has long been used in traditional and integrative medicine for gastrointestinal complaints, including ulcers and mild reflux symptoms.
- Form: Chewable tablets, gummies, or powders—chewable forms are preferred.
- Regulation: Marketed as an herbal supplement (less tightly regulated than prescription drugs in many countries).
- Main use: Mucosal healing and support rather than acute acid neutralization.
Main Benefits of DGL
- Supports healing of esophageal and gastric mucosa.
- May decrease recurrence rates of ulcers.
- Generally well-tolerated and safe for most users.
Limitations
- Not for immediate relief; benefits develop over days to weeks.
- Individual variability in response is possible.
- Less robust regulatory oversight compared to OTC/pharmaceutical drugs.
How Do Antacids and DGL Work?
| Remedy | Main Mechanism | Time to Onset | Site of Action |
|---|---|---|---|
| Antacids | Directly neutralize hydrochloric acid in the stomach | Within minutes | Stomach |
| DGL | Promotes mucosal protection by increasing mucus production and blood flow to tissues; enhances mucosal cell growth and healing | Typically days to weeks | Esophagus and gastric lining |
Efficacy for Mild Heartburn: DGL vs. Antacids
Antacids: Evidence and Effectiveness
- Numerous studies confirm that antacids rapidly neutralize stomach acid and provide symptom relief for most cases of mild, episodic heartburn.
- Does not promote healing of underlying esophageal inflammation nor prevent recurrence once the effect dissipates.
- Frequent or excessive use can mask other gastrointestinal conditions, and may result in side effects such as bloating or altered bowel habits.
DGL: Evidence and Effectiveness
- DGL has been shown in human clinical trials to outperform routine antacids for mucosal healing, symptom reduction, and prevention of recurrence in peptic and duodenal ulcers.
- In comparative trials (e.g., ulcers or severe reflux), DGL produced similar or superior healing rates and significantly lower recurrence than antacids (8.2% vs 16.4% relapse rates).
- For heartburn, DGL’s main action is in restoring mucosal defenses rather than providing immediate symptomatic relief.
- A 2017 review reported that DGL may be more effective than regular antacids at managing gastric and intestinal irritation, and is also beneficial for esophageal mucosa healing.
Key Comparative Insights
- While antacids are best for acute, transient relief, DGL is preferred for long-term mucosal support and relapse prevention.
- DGL does not combine with antacids for immediate effect; instead, it strengthens the body’s own protection, potentially reducing the need for future antacid use.
- Direct head-to-head studies suggest DGL is at least as effective as antacids short-term, and more effective for preventing recurrence and supporting tissue healing.
Speed and Duration of Relief
- Antacids: Provide relief in 5–15 minutes, but the effect typically lasts only 1–3 hours depending on the agent.
- DGL: Onset of noticeable benefit is slower (several days to a week), but continued use may reduce episode frequency and promote mucosal health for weeks or months.
For people seeking immediate relief of mild discomfort after meals, antacids are more suitable. Those with frequent heartburn or erosive symptoms benefit more from regular DGL supplementation—especially if episodes are recurrent.
Long-Term Benefits and Safety Profiles
Antacids: Safety and Limitations
- Generally safe for infrequent use.
- Overuse can lead to electrolyte disturbances in people with kidney or heart issues.
- May adversely affect absorption of other medications (e.g., antibiotics, thyroid drugs).
DGL: Safety and Tolerance
- DGL is considered extremely safe with a very low risk of side effects.
- Removal of glycyrrhizin avoids risk of raised blood pressure and potassium loss associated with standard licorice supplements.
- Chewable forms are superior; capsules are less effective for esophageal issues, as DGL must mix with saliva.
- Suitable for prolonged use (up to several months), especially for chronic or recurrent symptoms.
Special Considerations
- DGL is not suitable for those with proven licorice allergy.
- Pregnant or breastfeeding women should consult a healthcare provider before use.
- Children, elderly, or those on multiple medications should discuss DGL use with a doctor.
Recommended Usage and Dosage
DGL Best Practices
- Take 20 minutes before meals for best effect.
- Chew thoroughly (do not swallow whole), to maximize mucosal and salivary stimulation.
- Typical dose: 380–760 mg (per tablet/serving), two or three times daily; courses typically last 2–4 months.
- Pause after a course and reassess symptom changes before restarting; always inform your physician if integrating with other therapies.
Antacid Best Practices
- Take as needed for symptoms, usually after meals or at first sign of heartburn.
- Do not exceed labeled dose; long-term, frequent use should be monitored by a healthcare professional.
Which is Better for You?
The choice depends on symptom severity, frequency, underlying health, and personal preference:
- Antacids: Ideal for quick, situational symptom relief (occasional spicy meal, holiday overeating).
- DGL: Ideal for regular support, repeated symptoms, or when seeking to minimize pharmaceutical intake and support natural healing over time.
- Combination Approach: Some individuals may use antacids for acute symptoms while building up DGL’s benefits for long-term care. However, always consult a healthcare provider for persistent or worsening symptoms, or before combining remedies.
Frequently Asked Questions (FAQ)
Q: Can I take DGL and antacids together?
A: Yes, but space them apart. Antacids are for immediate relief; DGL supports mucosal healing long-term. If symptoms persist or worsen, see a healthcare provider.
Q: How long before I notice benefits from DGL?
A: Most users observe benefits after 5–7 days of regular use, with maximum effect over several weeks.
Q: Are there side effects to DGL?
A: DGL is typically very safe; rare side effects may include mild digestive upset. DGL is suitable for many people who have issues with traditional antacids.
Q: Who should avoid antacids?
A: Individuals with kidney disease, severe heart conditions, or on certain medications should consult a doctor before using antacids regularly.
Q: Is DGL effective for everyone with heartburn?
A: DGL is most effective for mild to moderate symptoms and for those with mucosal irritation. Its benefits for severe GERD or erosive esophagitis are less certain.
Q: Is there a risk of high blood pressure with DGL?
A: No. Deglycyrrhizinated licorice has the glycyrrhizin removed, making it safe for most people, including many with blood pressure concerns.
