Ingredient amounts are hidden inside “Viscous Fiber Matrix”
The panel lists “Viscous Fiber Matrix” (7.0 g) as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.

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.

The listing-image panel publishes 13 separately ingredients with amounts and 3 combined blend totals. Ingredients inside a blend do not have separate amounts.

FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a listed “proprietary blend” (legal, but a transparency yellow flag). A label stating no amount at all is non-compliant — a checkable red flag. This panel states amounts; the open question is whether those listed amounts are independently verified and how they compare with relevant research.

Every check we ran
Confirmed evidence
What checked out0
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Nothing could be independently confirmed from the available record.
Documented concerns
What needs caution1
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Unresolved public record
What is still missing5
We looked for these signals but could not settle them from public sources. A gap is not a strike.
Panel arithmetic needs confirmation
The listing-image panel produced 17,800 mg across 9 actives for an ≈11,000 mg serving. That cannot be reconciled; the physical label or another exact filed document must settle it.
Review-count history: not available
Marketplace rating not shown★ — rating count unavailable. No exact-listing count history was available, so no review-pattern claim is made.
Research context is available for the listed ingredients
Published sources describe how prebiotic fiber have been studied. This is ingredient context only; the record does not establish that this product delivers the studied dose or outcome. Sources: NIH ODS — Fiber overview (MVMS context), PubMed search: inulin prebiotic randomized trial.
No recall found — which is not the same as being tested
This means only that no enforcement record matched the brand name — it does not mean the product was tested, reviewed, or cleared by FDA. New and untested products also have no recall records.
Brand ownership record not saved
This record does not hold an exact, supplement-class public ownership record for the brand. That is a LookCloser coverage gap, not evidence that the brand has no owner or that the product is improper.
What to ask and check
What would settle the open questions
Why is this shown?
Everything we couldn’t verify is something a person can still ask about. Rather than leave gaps sitting as dead ends, we turn each one into a specific question — the exact document, citation, or number that would settle it — plus the things you can confirm yourself with the bottle in your hand.
Ask the brand or seller
1
What is the product’s UPC or GTIN?
The barcode is how a product gets matched to outside records — certification registries, label databases, recall data. Without it, almost nothing can be cross-checked.
2
Is this label filed with NIH’s Dietary Supplement Label Database (DSLD)?
Filing is voluntary, so absence proves nothing — but a filed label puts the full ingredient table on public record where anyone can read it.
3
What is the amount of each ingredient inside the proprietary blend?
A blend total tells you nothing about whether any single ingredient reaches a dose used in research. Brands may decline — that answer is informative too.
Most brands and sellers publish a contact route. A clear answer adds evidence to the record; no answer leaves the question open.
Check for yourself — no one’s permission needed
1
Compare the panel on the bottle in your hand to the one shown in this record.
Ours was read from listing photos and can contain reading errors. The physical label is the source of truth — if they disagree, tell us and we’ll correct the record.
2
Check the lot number and expiry on the bottle against any COA you’re given.
A certificate that doesn’t name your lot doesn’t describe what you’re holding.
These are the open questions on this specific record — not a warning about the product, and not a suggestion to buy or avoid it. Getting them answered is how you decide for yourself.
What the listing promises — claim by claim
Why is this shown?
A listing’s promises are the reason people buy. Each one gets its own row: what was promised, what evidence would settle it, and what we could actually find. We never call a claim false — only whether proof proportionate to it exists on the public record.
| Claim | Status | What we found |
|---|---|---|
| Benefit claim “…Combined with sunflower lecithin and ginger powder for comprehensive digestive support.…” | 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. 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.
This label vs. the doses studied
Why is this shown?
An ingredient can be well-studied at one amount and barely studied at the amount in your bottle. This lines the label up against the doses researchers actually used. It answers ‘are these the same numbers?’ — never ‘should you take this?’
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Dietary Fiber | shaded = doses used in studies (3 g–10 g) · bar = this label | 7 g — within the studied range |
Matching a studied dose does not mean the product works, and missing it does not mean it fails — it shows whether the label and the research are talking about the same amounts. Not a recommendation to take any amount.
