Natural Remedies for Peptic Ulcers: Evidence-Based Guide to Supplements and Alternative Treatments

Dr GutFeelJuly 21, 2026Gut Health

Important Disclaimer: Natural Doesn’t Mean Safe or Sufficient

Critical Point: Peptic ulcers are a serious medical condition that requires proper diagnosis and treatment. Untreated ulcers can lead to life-threatening complications (bleeding, perforation, obstruction).

What Natural Remedies CAN Do:

Support conventional medical treatment
Enhance H. pylori eradication rates
Reduce treatment side effects
Support mucosal healing
Potentially reduce recurrence risk
Manage symptoms during healing

What Natural Remedies CANNOT Do:

Reliably eradicate H. pylori as monotherapy
Replace antibiotics for H. pylori infection
Heal ulcers quickly without acid suppression
Prevent serious complications
Replace medical evaluation and monitoring

Bottom Line: Use natural remedies as COMPLEMENTS to—not replacements for—conventional medical treatment.

Probiotics: Best-Supported Natural Therapy

Probiotics have the strongest evidence base of any natural remedy for peptic ulcers, particularly for H. pylori treatment.

How Probiotics Help

Mechanisms:

Compete with H. pylori for adhesion sites
Produce antimicrobial substances
Modulate immune response
Strengthen gut barrier function
Reduce antibiotic-associated side effects
May directly inhibit H. pylori growth

Evidence

Multiple meta-analyses show:

Probiotics + standard therapy increase eradication rates by 5-15% compared to standard therapy alone
Reduce antibiotic-associated diarrhea by 50-60%
Reduce overall side effects of H. pylori treatment
May reduce H. pylori colonization even without antibiotics

Research Examples:

Meta-analysis of 42 studies (5,000+ patients): Probiotics increased eradication rates from 72% to 82%
Systematic review: Lactobacillus and Bifidobacterium strains most effective
Pediatric studies: Similar benefits in children

Best Strains for Ulcers

Most Studied and Effective:

Strain	Dose Studied	Benefits
Lactobacillus rhamnosus GG	10-20 billion CFU daily	Reduces antibiotic side effects, modest increase in eradication
Saccharomyces boulardii	250-500 mg twice daily	Reduces diarrhea, increases eradication rates
Bifidobacterium lactis HN019	1-10 billion CFU daily	Supports gut barrier, immune modulation
Lactobacillus reuteri DSM 17938	100 million-10 billion CFU daily	Anti-H. pylori effects, reduces side effects
Bifidobacterium infantis 35624	1-10 billion CFU daily	IBS symptom relief, gut support
Multi-strain products (VSL#3, Visbiome)	100-400 billion CFU daily	Broader coverage, may be more effective

How to Take Probiotics with H. pylori Treatment

Timing is Critical:

Standard H. pylori Treatment (14 days):
- Antibiotics (amoxicillin, clarithromycin, metronidazole, etc.)
- PPI (omeprazole, etc.)
- Bismuth (in some regimens)

Probiotic Protocol:
- Start probiotics DAY 1 of antibiotic treatment
- Take probiotics 2-3 hours AFTER antibiotics (antibiotics kill probiotic bacteria)
- Continue probiotics throughout 14-day antibiotic course
- Continue probiotics 2-4 weeks AFTER finishing antibiotics

Practical Example:

Morning (7 AM): PPI (before breakfast)
Breakfast (7:30 AM): Antibiotics #1 and #2
Lunch (12 PM): Probiotic
Dinner (6 PM): Antibiotics #1 and #2
Bedtime (10 PM): Probiotic (optional second dose)

Food Sources vs. Supplements

Probiotic Foods:

Yogurt with live cultures (6-8 oz daily)
Kefir (1/2 – 1 cup daily)
Sauerkraut (refrigerated, unpasteurized, 2-4 tbsp daily)
Kimchi (refrigerated, 2-4 tbsp daily)
Miso (1-2 tbsp in soup daily)
Tempeh (3-4 oz serving)

Pros: Safe, nutritious, generally well-tolerated
Cons: Variable CFU counts, may not contain specific strains, lower potency

Probiotic Supplements:

Standardized doses
Specific strains with research
Higher CFU counts
Shelf-stable options available

Pros: Consistent dosing, specific strains, convenient
Cons: More expensive, quality varies by manufacturer

Recommendation: Use both food sources AND supplements during H. pylori treatment for maximum benefit.

Safety and Side Effects

Generally Safe:

Well-tolerated by most people
Mild gas/bloating initially (usually resolves in 1-2 weeks)
Take with food to reduce side effects

Use Caution:

Severely immunocompromised patients (rare risk of bloodstream infection)
Critical illness
Central venous catheters
Short bowel syndrome

Discuss with doctor before use if you have serious medical conditions.

Deglycyrrhizinated Licorice (DGL)

Licorice root has been used for digestive complaints for thousands of years. DGL is a modified form that removes glycyrrhizin (which can raise blood pressure).

How It May Help

Proposed Mechanisms:

Stimulates mucus production
Increases blood flow to gastric mucosa
Promotes epithelial cell regeneration
Anti-inflammatory effects
May inhibit H. pylori growth

Evidence

Clinical Studies:

Small studies show DGL may enhance ulcer healing
One study: DGL + conventional therapy healed 91% of ulcers vs. 74% with conventional therapy alone
More research needed, but results are promising
May be more effective for symptom relief than H. pylori eradication

Dosing

Standard Dose:

DGL chewable tablets: 380-400 mg
Frequency: 3 times daily, 20 minutes before meals
Duration: 4-8 weeks (through ulcer healing phase)

How to Take:

Chew tablets thoroughly (don’t swallow whole)
Take before meals (allows coating of stomach lining)
Continue for full healing period

Safety and Side Effects

DGL (deglycyrrhizinated) is safe:

Glycyrrhizin removed (doesn’t raise blood pressure)
Generally well-tolerated
Rare side effects

Avoid Regular Licorice (with glycyrrhizin):

Can raise blood pressure
Can cause potassium loss
Can interact with medications
Not safe for long-term use

Contraindications:

Severe kidney disease
Severe heart disease
Pregnancy (limited safety data)

Antioxidant effects

Evidence

Mixed Results:

Lab studies: Mastic gum kills H. pylori in petri dishes
Small human studies: Some showed reduced H. pylori colonization
Larger/better studies: Failed to show significant H. pylori eradication
Current consensus: May have modest anti-H. pylori effects but INSUFFICIENT as monotherapy

Research Summary:

Study 1 (1998): 1 gram/day for 14 days eradicated H. pylori in some patients (small study)
Study 2 (2010): No significant eradication with mastic gum alone
Study 3 (2018): Mastic gum + antibiotics showed slightly better results than antibiotics alone (needs confirmation)

Bottom Line: Mastic gum may provide supportive benefits but should NOT be relied on as primary H. pylori treatment.

Honey (Especially Manuka Honey)

Honey has been used for wound healing for thousands of years. Manuka honey (from New Zealand) has particularly strong antibacterial properties.

How It May Help

Mechanisms:

Natural antibacterial properties (hydrogen peroxide, methylglyoxal in Manuka)
Anti-H. pylori effects (lab studies)
Anti-inflammatory
Antioxidant
Soothes irritated tissue
Prebiotic effects (feeds beneficial bacteria)

Evidence

Lab and Animal Studies:

Honey inhibits H. pylori growth in petri dishes
Manuka honey more effective than regular honey
Animal studies show reduced gastric inflammation

Human Studies:

Limited but promising
Small study: Honey + standard therapy showed trend toward better eradication (not statistically significant)
Anecdotal reports of symptom improvement
More rigorous studies needed

Bottom Line: Honey is safe and may provide supportive benefits, but evidence is weaker than for probiotics, DGL, or zinc carnosine.

Dosing

Common Approach:

Manuka honey: 1-2 teaspoons
Frequency: 2-3 times daily
Take: On empty stomach (morning and between meals)
Duration: 4-8 weeks

How to Use:

Take directly by spoonful
Mix with warm (not hot) water or herbal tea

Broccoli Sprouts (Sulforaphane)

Broccoli sprouts are rich in sulforaphane, a compound with anti-H. pylori effects.

How It May Help

Mechanisms:

Sulforaphane inhibits H. pylori growth
Reduces H. pylori colonization
Anti-inflammatory effects
Antioxidant
May reduce gastric inflammation and damage

Evidence

Human Studies:

Study 1: Broccoli sprouts (70g daily for 8 weeks) reduced H. pylori colonization and gastric inflammation
Study 2: Sulforaphane-rich broccoli sprout extract reduced H. pylori levels
Study 3: Effect was temporary—H. pylori returned after stopping sprouts
Bottom line: Broccoli sprouts may suppress (but not eradicate) H. pylori

Best Use: As adjunct to antibiotic therapy, not replacement

Dosing

Approaches:

Fresh Broccoli Sprouts:

50-70 grams daily (about 1/2 – 1 cup)
Eat raw (cooking destroys sulforaphane)

Ongoing symptoms
High risk (need ongoing NSAIDs)
Discuss with doctor

Frequently Asked Questions

Can I treat H. pylori naturally without antibiotics?

No. While some natural remedies show anti-H. pylori effects in lab studies, none reliably eradicate H. pylori in humans as monotherapy. Attempting to treat H. pylori without antibiotics risks:

Treatment failure
Ulcer complications (bleeding, perforation)
Increased cancer risk (untreated H. pylori is a risk factor for gastric cancer)
Spreading infection to others

Best approach: Use natural remedies to SUPPORT (not replace) antibiotic treatment.

Which natural remedy works best for ulcers?

Probiotics have the strongest evidence for enhancing H. pylori eradication and reducing treatment side effects. Zinc carnosine and DGL have good evidence for supporting ulcer healing. These three have the best risk-benefit profiles.

How long do I need to take natural remedies?

During antibiotic treatment: Probiotics, DGL, zinc carnosine
Healing phase (4-8 weeks): Continue PPI, probiotics, zinc carnosine
After healing: Focus on diet and lifestyle; supplements usually not needed unless recurrent ulcers

Can I take all these supplements together?

Generally, probiotics, DGL, zinc carnosine, and Manuka honey can be taken together safely. However:

Space probiotics 2-3 hours from antibiotics
Space zinc carnosine 2 hours from antibiotics
Don’t exceed recommended doses
Discuss with your doctor, especially if taking other medications

Are natural remedies safe during pregnancy?

Safety data is limited for most supplements during pregnancy. Safe options:

Probiotic foods (yogurt, kefir)
Food-based remedies (honey in moderation, broccoli sprouts in food amounts)
Ginger (for nausea; well-studied in pregnancy)

Avoid or discuss with OB before using:

DGL (limited safety data)
Zinc carnosine (limited safety data)
Mastic gum (insufficient data)
Herbal supplements (many lack pregnancy safety data)

Do natural remedies work for NSAID-induced ulcers?

Natural remedies may support healing, but the most important step is stopping or reducing the NSAID. Probiotics, zinc carnosine, and DGL may help. PPIs are still the cornerstone of treatment.

Can I drink alcohol while taking these supplements?

Best to avoid alcohol during active ulcer treatment. Alcohol:

Irritates stomach lining
Increases acid production
Delays healing
Interacts dangerously with metronidazole (H. pylori treatment)

Wait until after treatment is complete and ulcer has healed.

Conclusion

Natural remedies can play a valuable supportive role in peptic ulcer treatment, but they must be used appropriately—as complements to, not replacements for, conventional medical care.

Best-Supported Remedies:

Probiotics: Enhance eradication rates, reduce side effects
Zinc carnosine: Supports ulcer healing
DGL: May support mucosal healing and symptom relief
Manuka honey: Antibacterial properties, soothes tissue
Broccoli sprouts: May suppress H. pylori

Key Principles:

Complete prescribed antibiotic treatment
Take PPIs as directed
Use natural remedies to support, not replace, medical treatment
Discuss supplements with your healthcare provider
Focus on diet and lifestyle for long-term prevention

With the right combination of conventional treatment and evidence-based natural support, most peptic ulcers heal completely within 4-8 weeks, and H. pylori is successfully eradicated in 85-90% of cases.

Medical Disclaimer: This article is for educational purposes only and does not constitute medical advice. Peptic ulcers require proper medical diagnosis and treatment. Always consult with a qualified healthcare provider before starting any new supplement, especially if you are taking medications, have underlying medical conditions, or are pregnant/breastfeeding. Do not delay or discontinue prescribed medical treatment in favor of natural remedies.
