The panel states Potassium 99 mg per serving.
Rebuilt from public sources on July 22, 2026 · evidence availability is not a safety or effectiveness verdict.
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

Specific fact confirmed
Open Food Facts resolves 817716014043 to "potassium gluconate" () — consistent with this listing.
We 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 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.

This is the USPTO owner of the brand wordmark. It tells a shopper who is behind the brand, but does not by itself identify the manufacturer or prove where this product was made.
Review counts rose gradually. Written-review counts rose from 620 to 671 across the observed period. That describes count movement, not review authenticity or product quality. A variation family may share some public counts.

Can the testing claim be tied to a named laboratory and this product lot? Evidence that would settle it: lot-specific COA naming the laboratory and matching the product lot.

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.
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.
The listing claims third-party testing without naming any lab or certifier, so the claim can't be verified as stated.
Brand-level context only, not a finding about this product. BEST NUTRITIONALS LLC recalled a different or not-exactly-bound product on 2022-08-29: “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” (status: Terminated). The recalled product 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” — not necessarily the product on this page. Verify at FDA’s recall database.
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 620 on 2026-01-26 to 671 on 2026-07-08 (net +51). 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
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.
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 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.
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.
