“Certified”
Evidence →“GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check.

Does the marketing hold up?
Ingredient amounts are hidden inside “Proprietary Blend”. A blend total may be legal, but it prevents you from knowing whether any individual ingredient reaches a meaningful amount.

“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.

“WonderBiotics GLP-1 Support Fiber Supplement 6g Powder Packets - 30”
Evidence →Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.
Ingredient research can support context, but it is not a trial of this exact product.
△Claimed without support found1
“REGULAR POOPS, FEWER CRAVINGS AT NIGHT: Formulated by industry-leading microbiome scientists, this daily fiber supplement delivers the clinically…”
Evidence →We found no named, citable study of this product or formula. The claim may rest on ingredient research rather than a trial of this product.
?Couldn’t verify independently1
“Tested”
Evidence →No named laboratory or lot-specific certificate was found for this exact product. The exact brand page names no testing issuer and links no product-bound report. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.
We looked and found no public proof. That does not count against the product.

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 5 g of prebiotic fiber (inulin-type) per serving. Studies we found used 3 g–10 g a day, so this sits inside 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.
