H. pylori and gut health claims: what TikTok gets wrong

What did @drtoddstrong actually say?

The core argument here is that H. pylori is chronically undertreated because standard antibiotic triple therapy fails in 20-30% of cases due to biofilm protection, and that specific natural compounds can fill the gap. He names mastic gum at "1000 milligrams twice daily," serrapeptase and N-acetyl cysteine as biofilm disruptors, and zinc carnosine plus DGL licorice as repair agents. He also connects untreated H. pylori to leaky gut, autoimmune disease, B12 deficiency, and peripheral neuropathy, framing these as a mechanistic chain his patients regularly respond to.

He's selling a free masterclass at the end, which is worth noting. That doesn't automatically make his claims wrong, but it does mean the framing is designed to move people toward his protocol, not just inform them.

Does the science back this up?

Partially, and more than you might expect from a TikTok peptide account. The antibiotic failure rate figure is accurate. The biofilm concern is real but more contested than he implies. The mastic gum claim has actual evidence behind it, though modest. The autoimmune and neuropathy links are supported but presented with more certainty than the literature warrants.

H. pylori eradication with standard triple therapy (a proton pump inhibitor plus two antibiotics) achieves roughly 70-85% success in clinical practice, though rates vary significantly by region and clarithromycin resistance patterns (Malfertheiner et al., 2022, Gut). That matches his stated range. Biofilm formation by H. pylori has been documented in vitro and in some clinical samples (Carron et al., 2006, Journal of Gastroenterology and Hepatology), though whether biofilm disruption with oral enzymes meaningfully improves clearance in humans is not yet established by randomized trials. Mastic gum does show antimicrobial activity against H. pylori in vitro and in small clinical studies (Huwez et al., 1998, New England Journal of Medicine correspondence; Dabos et al., 2010, Phytomedicine), including against some resistant strains. The effect sizes are modest and the evidence base is thin. It is not a substitute for antibiotics in most cases.

What did they get wrong or right?

He got the mechanism of urease production and stomach acid neutralization right. That is textbook H. pylori physiology (Marshall and Warren, 1984, Lancet). The downstream logic connecting low stomach acid to impaired protein digestion and B12 malabsorption is also grounded. B12 requires intrinsic factor and adequate gastric acid for absorption, and H. pylori gastritis does impair this (Kaptan et al., 2000, Archives of Internal Medicine).

Where he overreaches is on the autoimmune connection. The link between H. pylori and autoimmune conditions is an active research area with some evidence for specific conditions like immune thrombocytopenic purpura, but framing it as "the foundation of autoimmune disease" is a significant overclaim. The leaky gut mechanism he describes, undigested proteins crossing the gut lining and triggering immune reactivity, is a plausible hypothesis, not an established causal chain. He presents it as settled science, and it is not.

The dosing recommendation of mastic gum at 1000 mg twice daily mirrors what was used in Dabos et al. 2010. Repeating a study dose is different from prescribing, but it is still something to flag: this article does not endorse that dose, and readers should consult a provider.

What should you actually know?

H. pylori is genuinely one of the most common chronic bacterial infections on earth, and the WHO classifies it as a Group 1 carcinogen for gastric cancer. Getting tested if you have persistent GI symptoms, unexplained B12 deficiency, or a history of ulcers is reasonable and evidence-backed. A urea breath test or stool antigen test are the standard non-invasive diagnostics.

If you have failed one antibiotic course, the clinical recommendation is not to just try again with the same regimen. Quadruple therapy or bismuth-based regimens are recommended as second-line treatment by the American College of Gastroenterology. The biofilm disruption protocol he describes, using serrapeptase or NAC before antibiotics, has biological plausibility but lacks clinical trial evidence in humans. Mastic gum may be a useful adjunct but is not a replacement for medical treatment. Zinc carnosine has good evidence for gastric mucosal repair (Mahmood et al., 2007, Journal of Nutritional Biochemistry). None of these are regulated as drugs in the US. If you are on a second round of antibiotics and still testing positive, that conversation belongs with a gastroenterologist, not a TikTok masterclass.
