About
IBSProbiotics.org is an independent, clinician-founded resource that cuts through marketing hype to make probiotic science clear, accessible, and practical for people with IBS. We review global guidelines and the highest quality clinical trials to identify the probiotic strains that show the most promise, and share this evidence in plain language so patients, clinicians, and product developers can make confident, informed decisions.
To help people with IBS, the clinicians who support them, and the formulators who create probiotic products find options backed by evidence rather than marketing spin. We believe that clear, trustworthy information leads to better decisions, better outcomes, and better products.
We see a future where probiotics are not only chosen for their demonstrated benefits but also developed with precision for specific IBS symptoms. By organizing and analyzing existing research, we aim to identify the most promising strains and combinations. This work can guide future head-to-head trials, validate effectiveness, and inspire the creation of next-generation probiotics designed for targeted, measurable results.
We collect the latest global guidelines on probiotics in IBS and review the highest quality clinical trials to identify the strains that show the most promise for improving common IBS symptoms. We share these findings in clear, practical language so they can be used confidently by patients, clinicians, and those developing new probiotic products.
We begin with one question: Does the evidence truly support this? Our process focuses on high-quality, placebo-controlled trials, applies clear evaluation standards, and shares the results in a way that is easy to understand.
