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.
Every check we ran
Ingredient amounts are hidden inside a blend
The panel lists “Turmeric Curcumin Complex” as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.
Intake method matches the research
Nothing in this listing contradicts how these ingredients were studied (magnesium, turmeric / curcumin). For example, 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. Sources: NIH ODS — Magnesium fact sheet, PubMed search: magnesium glycinate supplementation.
Registered in NIH's supplement label database (DSLD)
Label #277240 “Turmeric Curcumin with BioPerine” (Nature's Nutrition), entered 2022-09-22, with the full Supplement Facts on file — see the panel below. Company on file: Manufacturer — Nature's Nutrition, Bluffdale, UT.
Exact trademark owner identified
USPTO lists SILVERONYX LLC (LIMITED LIABILITY COMPANY) in 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.
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.
Multi-ingredient formula — panel read, serving weight unknown
We read the full Supplement Facts panel from the photos (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.
180-day review-count history is on file
Exact-listing history records written-review counts from 1,560 on 2026-01-29 to 1,565 on 2026-07-12 (net +5). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
This item belongs to a catalog variation family
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.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Quality-testing claim “…CERTIFIED FACILITY VEGAN BOTTLED IN THE USA LAB TESTED QUALITY ASSURED BIOPERINE®” | 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. |
| Manufacturing claim “…uminoids WITH BIOPERINE® 1950 mg per serving GMP CERTIFIED FACILITY VEGAN BOTTLED IN THE USA…” | Claimed, not verifiable We looked for: the facility registration or certificate behind the claim | Facility-level claims can be accurate and still say nothing about this product’s contents. No registration document was located. |
| Benefit claim “…est Absorption - Daily Joint & Immune Health Support, Vegan, Non-GMO, Bottled in USA - 240 Capsul…” | 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 | Studies typically use 200 mg–420 mg. This product’s amount could not be read from public sources, so no comparison is possible. | |
| Turmeric Curcumin Complex | shaded = doses used in studies (500 mg–2 g) · bar = this label | 1.95 g — 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
- 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 — 2 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.

Turmeric — NIH ODS · MedlinePlus · PubMed (1,288) · botanical; rare hepatotoxicity reports
Reference data from the NIH Office of Dietary Supplements, IOM Dietary Reference Intakes, and PubMed. A Tolerable Upper Intake Level is a documented reference figure, not a safety verdict — both the declared amount and the reference are shown for your own judgment. LookCloser gives no medical advice.
Related research & consistency
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.
turmeric / curcumin — NIH NCCIH — Turmeric · PubMed search: curcumin bioavailability piperine · WebMD: turmeric · ClinicalTrials.gov — 286 registered studies
ℹ Use pattern in research: plain curcumin absorbs poorly — most positive trials pair it with piperine (black pepper) or a bioavailability-enhanced form.
