What this means for you · The useful read

What the public record can establish

The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

Panel, decoded

The 99 mg potassium claim matches the panel

MARKETING99 mg — listing title
PANELPotassium 99 mg — same amount
matches panel

We did the comparison: the listing claims 99 mg of potassium, and the listing-image panel shows 99 mg potassium 1 caplet. Those amounts agree. This is internal consistency, not independent lab testing.

Review counts rose gradually. Written-review counts rose from 282 to 351 across the observed period. That describes count movement, not review authenticity or product quality. A variation family may share some public counts.

Confirmed evidence

What checked out01

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.

Confirmed

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 missing06

We looked for these signals but could not settle them from public sources. A gap is not a strike.

The listing doesn't publish enough to check the math

The retained listing evidence does not establish net weight, unit count, per-serving dose, servings per container, so the dose claim cannot yet be checked against serving arithmetic. This is a neutral evidence gap, not a pass or strike.

No data

Multiple USPTO brand-owner records are shown

USPTO returned multiple live supplement-class records for the exact brand wordmark: NATURE'S BOUNTY, INC., NATURE'S BOUNTY (NY), INC., Société des Produits Nestlé S.A. (société anonyme (sa); SWITZERLAND). These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.

No data

No label filed with NIH's public catalog

The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.

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 282 on 2026-01-31 to 351 on 2026-07-15 (net +69). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.

No data

UPC valid, no independent record

Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.

No data

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.

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 074312011108.

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.
