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 5 listed rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Magnesium Complex | 300mg | — | |
| L-Theanine | 60mg | — | |
| Omega-3 | 50mg | — | |
| Vitamin B6 | 2mg | — | |
| Vitamin D | 25mcg | — |
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:google/gemini-flash-1.5 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.
USPTO lists Xiang Chen (INDIVIDUAL) in China 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.
Written reviews grew from 444 to 640 across 2026-02-18 – 2026-07-25 with no single manufactured spike (largest 30-day gain ~58).
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.
We read the full Supplement Facts panel from the listing-image panel (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 omega-3, 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 — Omega-3 Fatty Acids fact sheet, PubMed dose-response trial.
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 423 on 2026-02-04 to 640 on 2026-07-25 (net +217). 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
What is the product’s UPC or GTIN?
The barcode is how a product gets matched to outside records — certification registries, label databases, recall data. Without it, almost nothing can be cross-checked.
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.
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.
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 |
|---|---|---|
| Benefit claim “…Calm, Strawberry Flavor Healthy Sleep & Mood Support: Our magnesium glycinate drops for kids and…” | 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
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Omega-3 | shaded = doses used in studies (300 mg–1.8 g) · bar = this label | 50 mg — below the studied range |
| Magnesium Complex | shaded = doses used in studies (200 mg–420 mg) · bar = this label | 300 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.
Verifiability profile — 2 of 6 public signals

Related research & consistency
omega-3 (EPA + DHA) — NIH ODS — Omega-3 Fatty Acids fact sheet · PubMed dose-response trial · ClinicalTrials.gov — 684 registered studies
ℹ Use pattern in research: research measures EPA and DHA together, not the weight of the fish-oil concentrate; the panel must expose those rows separately.
magnesium — NIH ODS — Magnesium fact sheet · PubMed search: magnesium glycinate supplementation · WebMD: magnesium · ClinicalTrials.gov — 3,206 registered studies
ℹ Use pattern in research: daily oral use; chelated forms (glycinate) are studied for absorption — note labels may state compound mass rather than elemental magnesium, which differs ~7-fold.
These notes state where label numbers and marketing framing sit relative to published research — documentation for your own judgment, not medical advice. LookCloser does not advise for or against taking any supplement.
