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 500 mg niacin (as nicotinic acid) claim matches the panel
MARKETING500 mg — per-serving claim
PANELNiacin (as nicotinic acid) 500 mg — same amountNiacin (as nicotinic acid) 500 mg
matches panelWe did the comparison: the listing claims 500 mg of niacin (as nicotinic acid), and the listing-image panel shows 500 mg niacin (as nicotinic acid) 1 capsule. Those amounts agree. This is internal consistency, not independent lab testing.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Niacin (as nicotinic acid) | 500 mg | — |
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.
vision:google/gemini-flash-1.5 Amounts are shown as listed panel data, not independently lab-tested contents.
Every check we ran
Confirmed evidence
What checked out4
These checks found support in the public record. They confirm specific facts, not the product as a whole.
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.
Exact trademark owner identified
USPTO lists eSupplements, LLC (LIMITED LIABILITY COMPANY) in UTAH, USA for the exact brand wordmark. This identifies the USPTO mark owner or applicant; it does not by itself prove who manufactures or sells this product.
Reviews accumulated gradually
Written reviews grew from 1436 to 1489 across 2026-02-08 – 2026-07-13 with no single manufactured spike (largest 30-day gain ~13).
Documented concerns
What needs caution1
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Dose claim implausibly high for a capsule
Claimed niacin 500.0 mg is 100% of the ≈500 mg serving (serving size on the label, keyed to UPC 810014679440) — above what gummy matrices realistically carry.
Unresolved public record
What is still missing6
We looked for these signals but could not settle them from public sources. A gap is not a strike.
Listing claim matches the label panel
The listing claims 500 mg; the photo-read Supplement Facts panel shows Niacin (as nicotinic acid) at 500 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
Public label filing not saved
This record does not currently hold an matched to this exact product public label filing for the exact product. That is a LookCloser coverage gap, not evidence that no filing exists.
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.
180-day review-count history is on file
Exact-listing history records written-review counts from 1,433 on 2026-01-28 to 1,489 on 2026-07-13 (net +56). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
Barcode record is too sparse to confirm identity
Open Food Facts resolves 810014679440 to "" (Nuticost), but that record lacks enough exact brand/product detail to confirm or contradict this listing.
Package and trademark records name different responsible entitie
The package says manufactured for: nutricost, 351 E 1750 N, Vineyard, UT 84059. USPTO names eSupplements, LLC as the exact wordmark owner. That can be a normal distributor, manufacturer, or licensing relationship; the saved records do not establish the relationship.
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
Answered by the panel: 0.5 g of the 0.5 g headline is niacin. Which independent lab can confirm that amount in this product?
The panel resolves the front-label arithmetic. The remaining question is lot-specific contents and stability; published category testing gives context, not a test of this product.
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
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
Scan the barcode on the package and confirm it reads 810014679440.
A mismatch between the barcode on the box and the one on the listing is worth pausing over — it can indicate a different variant, a repack, or a counterfeit.
3
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 “…ease Niacin Per Bottle Non-GMO, Gluten Free, 3rd Party Tested Manufactured in an NSF Certified, GMP Compli…” | Partly supported We looked for: the observed listing, saved brand product page, any linked COA or test report; NSF, IFOS, USP, Informed-Sport were not queried | A testing body is named on the listing, but we found no lot-specific certificate of analysis. |
| Manufacturing claim “…rty Tested Manufactured in an NSF Certified, GMP Compliant, FDA Registered Facility DIETARY S…” | Partly supported We looked for: the facility registration or certificate behind the claim | “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. |
| Benefit claim “…acinamide. Consuming On An Empty Stomach May Increase Flush Reaction 240 Capsules of fast release…” | Not checked yet We looked for: whether the ingredient doses on the label match the doses used in published research | Ingredient-level evidence for this formula isn’t in our knowledge base yet. Recorded as not checked yet — not as a negative. |
“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.
