Who we are

About Probiotic Science

Probiotic Science is an independent, evidence-first resource focused on a single ingredient: probiotic. We read the published human research, summarize what individual studies and pooled analyses report, and link to the primary sources so you can check them yourself.

What we do

• Summarize peer-reviewed and authoritative evidence on probiotic, with links to the original sources.
• Compare widely available probiotic products on form, labeled dose, transparency, and independent testing.
• State the limits of the evidence plainly, including who it applies to and who it does not.

How we stay honest

We are funded in part by affiliate commissions from retail links, which we disclose. Commerce never decides our editorial rankings: products become eligible for a comparison based on current Amazon popularity, but they are ranked by our own published methodology, not by commissions. We describe how each product was evaluated and what we could not verify.

What we are not

Nothing on Probiotic Science is medical advice, and our pages are not medically or doctor reviewed, clinically proven, or a substitute for guidance from a qualified professional. Evidence may not apply to every person, product, dose, or health condition.
