Myth-buster
A meta-analysis found that taking probiotics before H. pylori treatment raised eradication success from 70% to 80% — but the analysis pooled just 144 patients, making the finding intriguing but far from settled.
This is one of the first studies to examine probiotics pretreatment, so the result is a signal, not a sure thing — expect more data before acting on it.
In a meta-analysis of 144 patients, those who took probiotics before standard H. pylori therapy had an 80% eradication rate compared to 70% in the control group, a modest bump. The same analysis also found fewer side effects with probiotics pretreatment. However, the small sample size and lack of specified dosing mean the evidence is still too thin to change practice.
Where this fits in the evidence
This is among the first studies we've indexed on Lactobacillus acidophilus L-92 for Increased Helicobacter pylori Eradication Rate — treat it as an early signal until more research accumulates.
