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

?

Ingredient amounts are hidden inside a blend

The panel lists “Core Nutrients Blend” as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.

?

Testing claimed — but not publicly substantiated

The listing claims third-party testing without naming any lab or certifier, so the claim can't be verified as stated.

Intake method matches the research

Nothing in this listing contradicts how these ingredients were studied (prebiotic fiber, zinc, multivitamin / greens blend). 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.

Pack math confirmed from the label

28 servings × 20 g = 560 g, matching the printed net weight 560 g (NET WT. 1.23 lb (560 g)). Any different figure in the marketplace’s shipping-weight field describes packaging, not the product.

Registered in NIH's supplement label database (DSLD)

Label #332678 “Superfoods Greens Gummies” (Gruns), entered 2025-06-25, with the full Supplement Facts on file — see the panel below. Company on file: Manufacturer — Gruns.

Same barcode on the brand's own store

The brand's store lists this exact barcode as “Grüns” (variant: Low Sugar / 28 Packs) — identity confirmed across retailer listings.

UPC independently corroborated

Open Food Facts resolves 860011207108 to "Superfoods Greens Gummies" (grüns) — consistent with this listing.

No data yet: Review authenticity: not yet analyzed

Marketplace rating 4.2★ across 7,004 ratings. Authenticity not analysed: burst, purge and stockout patterns need price/review history.

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.

i

Brand holds NSF/ANSI 173 certification (brand-level)

Gruns Nutrition, Inc. appears in NSF’s certified-products registry with 2 certified product(s), but we couldn’t confirm this exact listing is among them. Closest listed product: “Nütrops by Grüns Functional Nootropics Gummies Sugar-Free”. Certification covers contents and contaminants — not effectiveness.

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.
ClaimStatusWhat we found
Clinical-evidence claim
“…s from prebiotics to help with digestion too CLINICALLY TESTED & SCIENCE-BACKED: Shown in a 12-week, placeb…”
No evidence located
We looked for: a named, citable clinical study of this product or formula
No named, citable study of this product or formula was located in public sources. The claim may rest on ingredient-level research rather than a trial of this product.
Quality-testing claim
“…ailable in low-sugar and sugar-free options. Third-party tested Grüns vitamin gummies you can feel good abou…”
Claimed, not verifiable
We looked for: a named laboratory, a certificate of analysis, or a certification-registry entry
No named laboratory, no certificate of analysis, and no certification-registry entry matching this product was located.
Benefit claim
“…s, 20+ Vitamins & Minerals, Digestion, Daily Support MULTIVITAMIN GUMMY THAT FILLS THE GAP: More…”
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.

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?’
IngredientWhere this label sitsReading
prebiotic fiber (inulin-type)Studies typically use 3 g–10 g. This product’s amount could not be read from public sources, so no comparison is possible.
Zinc
shaded = doses used in studies (8 mg–40 mg) · bar = this label
2.75 mg — below 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.

Documented cautions

Statements from published sources about these ingredients — not advice about this product, and not a complete safety review. Anyone taking medication should talk to a pharmacist or clinician.
