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.
Panel, decoded
The 250 mg omega-3 fatty acids (epa and dha combined) claim matches the panel
MARKETING250 mg — listing title
PANELOmega-3 Fatty Acids (EPA and DHA combined) 250 mg — same amountMagnesium (as Magnesium Citrate) 100 mg + Omega-3 Fatty Acids (EPA and DHA combined) 250 mg
matches panelWe did the comparison: the listing claims 250 mg of omega-3 fatty acids (epa and dha combined), and the listing-image panel shows 250 mg omega-3 fatty acids (epa and dha combined) 2 gummies. Those amounts agree. This is internal consistency, not independent lab testing.

Mass check · assumptions shown
3.35 g listed contents = 0.35 g major actives + 3 g carbohydrate
Assume 4 pectin gummies × 2.5–3.5 g each = 10–14 g serving. That leaves roughly 0–2 g for water, pectin, sweetener, acid, and flavor. Serving weight is not printed, so this is a warning, not a closed impossibility.
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; any remaining comparison concerns the front-label framing.

Every check we ran
Confirmed evidence
What checked out3
These checks found support in the public record. They confirm specific facts, not the product as a whole.
✓
EPA + DHA dose is within one studied range
The panel lists 500 mg EPA + DHA per serving (2 Gummies). One randomized dose-response trial used 300–1,800 mg/day; omega-3 studies vary widely. This is research context, not a recommendation or safety verdict.
Confirmed✓
Every ingredient amount is disclosed
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Confirmed✓
The review count moved gradually, not in one burst
Written reviews rose from 23 to 38 between August 9, 2025 and July 11, 2026. The largest rise inside any single 30-day window was about 4, so the count moved in steps rather than in one burst.
ConfirmedDocumented concerns
What needs caution1
These are documented contradictions or claims that need more evidence. They are separate from missing data.

The label says 3.35 g of omega-3 in 4 gummies — but not what tho
A serving is 4 gummies, and the panel lists 3,350 mg — 3.35 g — of omega-3 in that serving. What the panel doesn’t give is the one number needed to check it: what a serving weighs. Gummies of this type usually run somewhere around 2.5 to 3.5 grams each, which would put 4 of them near 10 to 14 grams. If that holds here, omega-3 would be a high share of the serving’s weight, and that is why we stopped on this number. But we did not weigh these gummies. The 2.5–3.5 gram figure is a general estimate for the format, not a measurement of this product. One published number would settle it: the weight of one gummy, or of a 4-gummy serving. Until then we can’t confirm the 3.35 g and we can’t dispute it. Nothing here says the product is short — only that the label doesn’t let anyone check. Checked August 15, 2026.
CautionUnresolved public record
What is still missing7
We looked for these signals but could not settle them from public sources. A gap is not a strike.
…
“Lab tested” claimed, but no lab or report named
The observed listing claims third-party testing without naming a lab or certifier. No product-bound report is saved, so the claim cannot be verified as stated. NSF, IFOS, USP, and Informed-Sport were not checked in this record.
No data…
Multi-ingredient formula — panel read, serving weight unknown
We read the full Supplement Facts panel from the listing-image panel (below), but the label doesn’t state a serving weight, so the arithmetic can’t run. A gap in the label’s information, not evidence of a problem.
No data…
Research context is available for the listed ingredients
Published sources describe how omega-3, magnesium, zinc 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 — Omega-3 Fatty Acids fact sheet, PubMed dose-response trial.
No data…
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.
No data…
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.
No data…
180-day review-count history is on file
Exact-listing history records written-review counts from 21 on 2025-08-01 to 38 on 2026-07-11 (net +17). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
No data…
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.
No dataWhat 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
Answered by the panel: the 0.25 g listing number equals Zinc (as Zinc Citrate) 10 mg + Omega-3 Fatty Acids (EPA and DHA combined) 250 mg. What lot-specific document confirms those listed amounts?
The panel resolves what the headline number includes. The remaining question is whether the product in hand matches those listed amounts; ask for a lot-specific certificate of analysis.
2
Can you send the certificate of analysis (COA) for the lot number on my bottle?
A real COA names the testing laboratory, the test date, the lot it covers, and what was measured. “Third-party tested” with no document behind it is a marketing sentence.
3
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.
4
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.
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 |
|---|
| Quality-testing claim “…LAB TESTED…” | Claimed, not verifiable We looked for: the observed listing, saved brand product page, any linked COA or test report; NSF, IFOS, USP, Informed-Sport were not queried | No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. 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. |
| Benefit claim “…Additionally, it's fortified with 250 mg of Omega-3 to enhance the absorption of fat-soluble vitamin k2 d3 in the body.…” | 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 |
|---|
| Omega-3 Fatty Acids (EPA and DHA combined) | shaded = doses used in studies (300 mg–1.8 g) · bar = this label | 250 mg — below the studied range |
| Magnesium (as Magnesium Citrate) | shaded = doses used in studies (200 mg–420 mg) · bar = this label | 100 mg — below the studied range |
| Zinc (as Zinc Citrate) | shaded = doses used in studies (8 mg–40 mg) · bar = this label | 10 mg — 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.
Documented cautions
- magnesium — daily oral use; chelated forms (glycinate) are studied for absorption — note labels may state compound mass rather than elemental magnesium, which differs ~7-fold
- zinc — daily oral use; sustained high intakes can interfere with copper absorption — a documented interaction, not advice
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.
