Does the marketing hold up?
Ingredient amounts are hidden inside “Probiotic Blend”. The panel lists “Probiotic Blend” (37 mg) as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.
Is the dose real?Panel read — dose not verified2 ingredients listed; no advertised amount we could confirm against them
What a serving costsNo price found for this exact barcode
Is it tested?USP seal printed on the labelwe read it off the package photo; not confirmed in USP’s registry
Who’s behind it?USPTO lists 2 owner recordssame brand name, more than one registrant — we don’t choose between them
Is it the real thing?No barcode publishedso it can’t be matched against certification, recall or other retailer records
Trouble on record?✓No recalls found
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

Research behind the findings
Dose and research context
We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.
Background reading
What the research says about these amounts
Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.
The panel lists 50 mg of prebiotic fiber (inulin-type) per serving. Studies we found used 3 g–10 g a day, so this sits below that range.
0studied 3 g–10 g
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
