UPC valid, no independent record

We did the comparison: the listing claims 500 mg of acetyl-l-carnitine, and the listing-image panel shows 500 mg acetyl-l-carnitine serving size 3 capsules. Those amounts agree. This is internal consistency, not independent lab testing.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Acetyl-L-Carnitine | 500 mg | — | |
| N-Acetyl-L-Cysteine (NAC) | 600 mg | — | |
| Alpha-Lipoic Acid | 600 mg | — | |
| Benfotiamine | 300 mg | — | |
| Thiamin (as thiamine mononitrate) | 50 mg | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a declared “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.

Review counts rose gradually. Written-review counts rose from 190 to 230 across the observed period. That describes count movement, not review authenticity or product quality. A variation family may share some public counts.

The summary stops at product-specific facts. The full report preserves every source, calculation, limitation, and unresolved check for review or sharing.
Confirmed evidence
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
These are documented contradictions or claims that need more evidence. They are separate from missing data.
No contradictions or product-specific cautions were found at this check depth.
Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
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.
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
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.
Exact-listing history records written-review counts from 190 on 2026-01-31 to 230 on 2026-07-14 (net +40). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.

What to ask and check
Ask the brand or seller
Answered by the panel: the 0.5 g listing number equals Acetyl-L-Carnitine 500 mg + Black Pepper (Piper nigrum) (Fruit) Extract (std. 95% Piperine) 5 mg. What lot-specific document confirms those declared amounts?
The panel resolves what the headline number includes. The remaining question is whether the product in hand matches those declared amounts; ask for a lot-specific certificate of analysis.
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.
Where are the ingredients sourced, and where is the product manufactured?
“Made in USA” can describe only the final bottling step. Ask which country the actives came from and whether the facility is audited.
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
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.
Scan the barcode on the package and confirm it reads 665355648101.
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.
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.
