Supplements Alongside H. pylori Treatment: Mastic…

Helicobacter pylori infects approximately half the global population and is the primary cause of peptic ulcers, chronic gastritis, and a significant risk factor for gastric cancer. Standard eradication regimens using two antibiotics plus a proton pump inhibitor achieve success rates of 70-90%, but antibiotic resistance is rising and side effects—including diarrhea, nausea, and Clostridioides difficile risk—lead to poor compliance. Integrative support with specific supplements can improve eradication rates, reduce side effects, and protect the gastric mucosa throughout treatment.

Probiotics During Antibiotic Therapy

Probiotics are the best-studied supplement adjunct to H. pylori eradication. A 2017 meta-analysis of 30 randomized controlled trials (4,302 participants) found that adding probiotics to standard triple therapy improved eradication rates by approximately 10-14% and significantly reduced antibiotic-associated adverse effects, particularly diarrhea. Lactobacillus rhamnosus GG, Lactobacillus reuteri DSM 17938, and Saccharomyces boulardii CNCM I-745 have the strongest individual evidence. Timing matters: probiotics should be taken at least two hours apart from antibiotics and continued for two to four weeks after the antibiotic course ends.

Mastic Gum

Mastic gum, a resin from Pistacia lentiscus trees native to the Greek island of Chios, has direct bactericidal activity against H. pylori. A landmark 1998 study in the New England Journal of Medicine found that 1 g of mastic gum daily for two weeks eradicated H. pylori in 7 out of 10 patients—a remarkable result for a natural compound used alone. Subsequent studies have varied in their outcomes, with mastic gum performing better as an adjunct to antibiotics than as monotherapy. The dose used in most trials is 1-2 g daily, divided into two doses taken on an empty stomach. Mastic gum may work by disrupting H. pylori's DNA gyrase and inhibiting the organism's urease enzyme.

DGL Licorice

Deglycyrrhizinated licorice supports the gastric mucosa during H. pylori treatment by stimulating protective mucus production and demonstrating in vitro inhibitory effects against H. pylori adhesion. While DGL alone cannot eradicate the infection, it reduces gastric inflammation and may improve the outcome of eradication therapy by restoring mucosal integrity. Dose: 380-760 mg as chewable tablets before meals.

Zinc Carnosine

Zinc carnosine (75 mg twice daily) has been shown in clinical trials to accelerate healing of gastric ulcers associated with H. pylori infection. It reduces mucosal inflammation, supports tight junction repair, and demonstrates mild direct antimicrobial activity against H. pylori in animal studies.

Cranberry Extract

Proanthocyanidins in cranberry extract prevent H. pylori from adhering to the gastric epithelium. A 2008 double-blind trial found that twice-daily cranberry juice consumption suppressed H. pylori infection in 14.4% of treated subjects versus 5% of controls over 90 days. While not curative, cranberry extract (400-500 mg standardized proanthocyanidins) can reduce bacterial load and may improve eradication rates when added to standard therapy.

Broccoli Sprout Extract

Sulforaphane, the bioactive compound in broccoli sprouts, induces phase-2 detoxification enzymes and has demonstrated direct bactericidal activity against H. pylori, including antibiotic-resistant strains. A clinical trial found that 70 g of broccoli sprouts daily for eight weeks significantly reduced H. pylori bacterial load and gastric inflammation markers. Standardized sulforaphane supplements (30-60 mg daily) offer a more convenient alternative.

FAQ

Should I take probiotics during or after antibiotic treatment? Both. Take probiotics during antibiotic therapy (spaced two hours from antibiotic doses) to reduce diarrhea and protect the microbiome, and continue for at least two to four weeks after finishing antibiotics to support recovery of gut flora diversity.

Can these supplements replace antibiotics? No. Mastic gum and other natural agents may suppress H. pylori but are unlikely to achieve complete eradication in most patients. They are most valuable as adjuncts that improve the outcome of standard medical treatment.

When should I test to confirm eradication? H. pylori breath tests and stool antigen tests should be performed at least four weeks after completing antibiotic therapy and at least two weeks after stopping PPIs to ensure accurate results.
