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.

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 listing amount and panel row need explanation
MARKETING595 mg — per-serving claim
PANELPotassium 99 mg — panel read
amount differsWe compared the listing claim (595 mg) with the panel row (99 mg potassium). They do not match within the report tolerance; the source label or serving basis needs checking.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Potassium | 99 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.

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
Exact trademark owner identified
USPTO lists VNH, LLC (LIMITED LIABILITY COMPANY) in DELAWARE, 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.
Found on the brand's own store
The brand's store lists this exact barcode as “Best Naturals Potassium Gluconate 595 mg 250 Tablets” (variant: Default Title) — identity confirmed across retailer listings.
Barcode confirmed in an outside database
Open Food Facts resolves 817716014043 to "potassium gluconate" () — consistent with this listing.
Documented concerns
What needs caution2
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Reviews arrived in a burst, not gradually
The dated series runs from 45 written reviews on August 7, 2025 to 690 on August 26, 2026. Up to 519 written reviews were added within a single ~30-day window — 75% of the total. Sudden bursts are the usual fingerprint of incentivized or bought reviews; a steady climb is not.
The label’s 595 mg reads 6× larger than the potassium on the pan
Salt weight, not the actual mineral. 595 mg is the weight of the potassium gluconate compound. The actual potassium in it is 99 mg. You are getting 99 mg of potassium per serving.
Unresolved 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.
Listing and photo-read panel need confirmation
The listing says 595 mg, while our photo read produced Potassium at 99 mg per serving. OCR can confuse small units and digits, so this remains unresolved until checked against the physical label.
“Lab tested” claimed, but no lab or report named
The observed listing and the exact brand product page both claim third-party testing. Neither names the laboratory or links a product- or lot-specific report. Repeating the claim across two pages confirms the brand publishes it, not that testing occurred. NSF, IFOS, USP, and Informed-Sport were not checked in this record.
FDA recall appears in this brand's history
This recall is not about the product on this page. BEST NUTRITIONALS LLC recalled a different product on August 29, 2022. FDA has since closed that case. The recalled item was “White plastic bottle with green, gold, and blue labeling containing 360, 610mg hard gelatin capsules of Fenugreek seed powder, labeled in part, "Best Naturals Fenugreek Premium Her”. FDA recorded the reason as “Best Nutritionals LLC 120 Centennial Ave, Piscataway NJ 08854, is initiating a recall of Fenugreek 610 mg , 360 Capsules ,in White Plastic HDPE bottles because the product has the potential to be contaminated with Salmo”. Verify at FDA’s recall database.
Public label filing not saved
We have not found a public label filing for this exact product. That is a gap in our records, 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 555 on 2025-07-31 to 690 on 2026-08-26 (net +135). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
Package and trademark records name different responsible entitie
The package says manufactured for: Best Naturals,, PO Box 394, Kenilworth NJ 07033 USA. USPTO names VNH, 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
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.
2
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.
3
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 817716014043.
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 “…3rd Party Lab Tested for Purity & Quality.…” | 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. The exact brand page repeats a testing claim but names no issuer. 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. |
| Manufacturing claim “…Proudly Made in USA, GMP Compliant, FDA Registered Facility.…” | 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. |
| Origin claim “…Proudly Made in USA, GMP Compliant, FDA Registered Facility.…” | Claimed, not verifiable We looked for: customs records or label filings showing where ingredients were sourced and where it was made | “Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product. |
“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.
