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.
The 500 mg potassium claim matches the panel
We did the comparison: the listing claims 500 mg of potassium, and the listing-image panel shows 500 mg potassium 2 capsules. Those amounts agree. This is internal consistency, not independent lab testing.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Vitamin B6 | 2 mg 118% | — | |
| Magnesium | 40 mg 10% | — | |
| Potassium | 500 mg 11% | — | |
| Taurine | 100 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.
vision:google/gemini-flash-1.5 Amounts are shown as declared panel data, not independently lab-tested contents.
Every check we ran
Exact trademark owner identified
USPTO lists The Health & Wellness Center Inc. (CORPORATION) in VIRGINIA, 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.
No data yet: Testing claimed — documentation not found
The listing claims third-party testing without naming any lab or certifier, so the claim can't be verified as stated.
No data yet: Review-count history: not available
Marketplace rating not shown★ — rating count unavailable. No exact-listing count history was available, so no review-pattern claim is made.
Listing claim matches the Supplement Facts panel
The listing claims 500 mg; the photo-read Supplement Facts panel shows Potassium at 500 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
Research context is available for the listed ingredients
Published sources describe how magnesium 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.
Not found in NIH's DSLD label registry
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
FDA recall appears in this brand's history
Brand-level context only, not a finding about this product. Health & Wellness Center, Inc. recalled a different or not-exactly-bound product on 2021-09-24: “Product recalled because of the presence of mold and/or yeast found in amounts that exceed the product's established specifications .” (status: Terminated). The recalled product was: “Dr. Berg Nutritionals, Liquid Vitamin D with Zinc Dietary Supplement ( Liquid Vitamin D ), Individual 1 FL OZ bottle (with no secondary packaging), Glass bottle. The label of t” — not necessarily the product on this page. Verify at FDA’s recall database.
UPC valid, no independent record
Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Quality-testing claim “…𝗠𝗣𝗟𝗘𝗧𝗘 𝗣𝗢𝗧𝗔𝗦𝗦𝗜𝗨𝗠 𝗖𝗢𝗠𝗣𝗟𝗘𝗫 + 𝗖𝗟𝗘𝗔𝗡 𝗙𝗢𝗥𝗠𝗨𝗟𝗔: 4X lab tested for purity and safety. Non-GMO, no fillers,…” | Claimed, not verifiable We looked for: a named laboratory, a certificate of analysis, or a certification-registry entry | No named laboratory, no certificate of analysis, and no certification-registry entry matching this product was located. |
| Professional-endorsement claim “…ural health. Supports healthy heart function Doctor Formulated 4X Lab Tested No Junk Non-GMO No Preservativ…” | Marketing credential We looked for: who the professionals are, whether they were compensated, and what the endorsement covers | A professional endorsement is a marketing credential, not clinical evidence. Public sources don’t establish who was consulted, whether they were paid, or what specifically they reviewed. |
| Benefit claim “…0 mg Potassium Supplement for Muscle & Nerve Support* – Maximum Strength Potassium Formula w/Magn…” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Published research exists for ingredients in this formula — see Related research below. Whether this product’s doses match those studies could not be confirmed. |
“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.
This label vs. the doses studied
Why is this shown?
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Magnesium | shaded = doses used in studies (200 mg–420 mg) · bar = this label | 40 mg — below the studied range |
Matching a studied dose does not mean the product works, and missing it does not mean it fails — it shows whether the label and the research are talking about the same amounts. Not a recommendation to take any amount.
Documented cautions
- magnesium — daily oral use; chelated forms (glycinate) are studied for absorption — note labels may state compound mass rather than elemental magnesium, which differs ~7-fold
Statements from published sources about these ingredients — not advice about this product, and not a complete safety review. Anyone taking medication should talk to a pharmacist or clinician.
Verifiability profile — 3 of 6 public signals
What this listing gives the public to check. Publishing these signals doesn't prove quality — but withholding them means claims can only be taken on faith.
