What is worth knowing.
Headlines first. Open evidence only when you want the source trail.
Checks outIs the label honest?
Every declared ingredient has an amount · 11 quantified rows.
You can compare each declared dose with research instead of guessing what is hidden inside a blend.
Evidence and sources
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Locked evidence record →Open the full source-linked findingChecks outWho is behind it?
The barcode identity checks out · 737870231363.
The outside identifier points to this product, so the other checks are less likely to be about a look-alike.
Evidence and sources
Open Food Facts resolves 737870231363 to "One per day multivitamin" (life extension) — consistent with this listing.
Locked evidence record →Open the full source-linked findingChecks outCan you trust the review pattern?
Written reviews moved 285 → 339 from 2026-02-04 to 2026-07-11 without one large burst.
Gradual growth is more ordinary; a sudden burst deserves a closer look. Neither pattern proves whether individual reviews are genuine.
Evidence and sources
Written reviews grew from 285 to 339 across 2026-02-04 – 2026-07-11 with no single manufactured spike (largest 30-day gain ~18).

Confirmed evidence
What checked out04
These checks found support in the public record. They confirm specific facts, not the product as a whole.
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 Life Extension Foundation, Inc. (['CORPORATION', 'CORPORATION']) in ['FLORIDA, USA', 'FLORIDA, 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.
Barcode confirmed in an outside database
Open Food Facts resolves 737870231363 to "One per day multivitamin" (life extension) — consistent with this listing.
Reviews accumulated gradually
Written reviews grew from 285 to 339 across 2026-02-04 – 2026-07-11 with no single manufactured spike (largest 30-day gain ~18).
Documented concerns
What needs caution00
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
What is still missing05
We looked for these signals but could not settle them from public sources. A gap is not a strike.
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.
Research context is available for the listed ingredients
Published sources describe how 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 — Magnesium fact sheet, PubMed search: magnesium glycinate supplementation.
Public label filing not retained
This record does not currently hold an identity-bound 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 285 on 2026-02-04 to 339 on 2026-07-11 (net +54). 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
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
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.
2
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
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 737870231363.
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.
