How to read this report
What this is. We compare what a listing claims against what public records show — label arithmetic, barcode registries, NIH’s label catalog, FDA enforcement data, certification registries, and published research. Every statement below traces to one of those.
What the states mean. Confirmed = an outside source agrees. Contradicted = an outside source disagrees. Caution = something needs explaining. No data = we looked and found nothing — a gap, not a strike.
What it is not. A clean record is not an endorsement and never proof a product works. A thin record is not an accusation. We publish evidence and gaps; the conclusion is yours. Nothing here is medical advice.
Something wrong? Every figure is meant to be checkable — sources are named and linked. Send a correction and we’ll fix the record.
Every check we ran
Intake method matches the research
Nothing in this listing contradicts how these ingredients were studied (prebiotic fiber). For example, prebiotic fiber: daily use; effects build over weeks as gut flora shift. Sources: NIH ODS — Fiber overview (MVMS context), PubMed search: inulin prebiotic randomized trial.
UPC independently corroborated
Open Food Facts resolves 030772146576 to "CLEAR FIBER BLEND" (Meta Mucil) — consistent with this listing.
Single-dose label math: not applicable to this formula
Multi-ingredient blend with no single headline dose to check, and no Supplement Facts panel was visible in the listing photos to check instead. A gap in the listing, not a strike.
Not found in NIH's DSLD label registry
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
180-day review-count history is on file
Exact-listing history records written-review counts from 289 on 2026-01-23 to 380 on 2026-07-14 (net +91). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
This item belongs to a catalog variation family
The paid catalog links this exact item to a parent listing. Review counts on public product pages may be shared across sizes, flavors, or other variants, so the count history is listing context — not evidence that reviewers received or tested this exact variant.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Benefit claim “…our coffee, smoothies, juice, tea, and more! PROMOTES REGULARITY* TO HELP RELIEVE OCCASIONAL CONST…” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Published research exists for ingredients in this formula — see Related research below. Whether this product’s doses match those studies could not be confirmed. |
“No evidence located” does not mean a claim is false — it means the seller has not put evidence proportionate to the claim on the public record, and we could not find any. Absence of proof is not proof of absence.
