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 listing-image panel publishes an amount for each of its 4 listed rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Calories | 5 | — | |
| Magnesium (as magnesium lysinate glycinate chelate) TRAACS® | 200 mg | — | |
| Sodium (as sodium bicarbonate) | 130 mg | — | |
| Potassium (as potassium bicarbonate) | 180 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.
vision:claude-cli:subscription 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 #270598 “MagSoothe Tart Raspberry Lemonade Flavor” (Jigsaw Health), entered 2022-06-16, with the full Supplement Facts on file. NIH marks this label as off-market (superseded or discontinued version). Company on file: Manufacturer — Jigsaw Health, Scottsdale, AZ.
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 Jigsaw Direct, LLC (LIMITED LIABILITY COMPANY) in ARIZONA, 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.
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.
Technical check only: the panel’s 2 actives sum to 380 mg, which fits inside the ≈5,500 mg serving. This means the numbers are physically possible — it does not mean the formula was validated or the contents confirmed.
60 servings × 5.5 g = 330 g, matching the printed net weight 324 g (NET WT 324 G). This checks agreement within the photo read; it is not an independent contents test.
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 169 on 2025-08-08 to 175 on 2026-05-22 (net +6). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
Open Food Facts resolves 876634001863 to "Mag soothe" (brand not supplied), but that record lacks enough exact brand/product detail to confirm or contradict this listing.
What to ask and check
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 876634001863.
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 |
|---|---|---|
| Speed-of-results claim “…Fast-Acting, Calming Magnesium Glycinate Powder Supplement…” | No evidence located We looked for: a study measuring the stated outcome over the stated time | We found no study of this product measuring the stated outcome over the stated timeframe. |
| Benefit claim “…Supports Sleep & Stress: Promotes healthy, restful sleep and a balanced response to stress.…” | 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 (as magnesium lysinate glycinate c | shaded = doses used in studies (200 mg–420 mg) · bar = this label | 200 mg — within 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.
