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 nih dsld label publishes an amount for each of its 1 listed row. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Magnesium | 150 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; the open question is whether those listed amounts are independently verified and how they compare with relevant research.
NIH DSLD label #271275 (public label filing for this exact product) Amounts are shown as listed panel data, not independently lab-tested contents.
Every check we ran
Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Label #271275 “Triple Calm Magnesium” (Natural Rhythm), entered 2022-07-21, with the full Supplement Facts on file. Company on file: Distributor — Natural Rhythm Nutrition, Keller, Texas.
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
USPTO lists Natural Rhythm, LLC (LIMITED LIABILITY COMPANY; CORPORATION) in TEXAS, USA; 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.
The brand's store lists this exact barcode as “Triple Calm Magnesium - 150mg of Magnesium Taurate, Glycinate, and Malate (Wholesale)” (variant: 1 Box - 12 Units) — identity confirmed across retailer listings.
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 observed listing claims third-party testing without naming a lab or certifier. No product-bound report is saved, so the claim cannot be verified as stated. NSF, IFOS, USP, and Informed-Sport were not checked in this record.
We read the full Supplement Facts panel from the NIH DSLD label (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.
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.
This means only that no enforcement record matched the brand name — it does not mean the product was tested, reviewed, or cleared by FDA. New and untested products also have no recall records.
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 1,670 on 2025-07-24 to 1,948 on 2026-08-23 (net +278). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
Open Food Facts resolves 764804317435 to "Magnesuim" (brand not supplied), but that record lacks enough exact brand/product detail to confirm or contradict this listing.
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.
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
Scan the barcode on the package and confirm it reads 764804317435.
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.
What the listing promises — claim by claim
| Claim | Status | What we found |
|---|---|---|
| Quality-testing claim “…Made in the USA in a cGMP-compliant facility and third-party lab tested for purity and potency you can trust.” | 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 names no testing issuer and links no product-bound report. 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. |
| Origin claim “…Made in the USA in a cGMP-compliant facility and third-party lab tested for purity and potency you can trust.” | 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. |
| Benefit claim “…It supports a calm nervous system and helps you drift into a restful sleep without next-day grogginess.…” | 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. 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
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Magnesium | shaded = doses used in studies (200 mg–420 mg) · bar = this label | 150 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
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.
