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.
We did the comparison: the per-serving claim uses 150 mg, which equals Turmeric Extract (95% Curcuminoids) (Curcuma longa)(root) 150 mg + BioPerine® (Black Pepper Extract) (Piper nigrum)(fruit) 10 mg. It is a combined amount, not the amount of one ingredient. The full listed active total is 3.91 g including the other panel rows. This explains the label framing; it does not independently test the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Turmeric Curcumin Complex | 1950 mg | — | |
| Organic Turmeric (Curcuma longa)(root) | 1800 mg | — | |
| Turmeric Extract (95% Curcuminoids) (Curcuma longa)(root) | 150 mg | — | |
| BioPerine® (Black Pepper Extract) (Piper nigrum)(fruit) | 10 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; any remaining comparison concerns the front-label framing.

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 #277240 “Turmeric Curcumin with BioPerine” (Nature's Nutrition), entered 2022-09-22, with the full Supplement Facts on file. Company on file: Manufacturer — Nature's Nutrition, Bluffdale, UT.
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.
Documented concerns
These are documented contradictions or claims that need more evidence. They are separate from missing data.
label claims 150 mg/serving — below the range commonly used in research (studies typically use 500–2,000 mg/day of curcuminoids). A lower dose is not necessarily useless — but it is not the amount the research used. Sources: NIH NCCIH — Turmeric, PubMed search: curcumin bioavailability piperine.
Blend total, not the star ingredient. 150 mg is the total for the whole blend. Only 1,950 mg is broken out on the panel, and the amount of turmeric itself is not disclosed. You are getting 1,950 mg of turmeric per serving.
Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
The listing says 150 mg, while our photo read produced Turmeric Curcumin Complex at 1.95 g per serving. OCR can confuse small units and digits, so this remains unresolved until checked against the physical label.
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.
Published sources describe how turmeric / curcumin have been studied. This is ingredient context only; the record does not establish that this product delivers the studied dose or outcome. Sources: NIH NCCIH — Turmeric, PubMed search: curcumin bioavailability piperine.
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 3,007 on 2025-07-04 to 3,006 on 2026-05-30 (net -1). 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
Answered by the panel: the 0.15 g listing number equals Turmeric Extract (95% Curcuminoids) (Curcuma longa)(root) 150 mg + BioPerine® (Black Pepper Extract) (Piper nigrum)(fruit) 10 mg. What lot-specific document confirms those listed amounts?
The panel resolves what the headline number includes. The remaining question is whether the product in hand matches those listed amounts; ask for a lot-specific certificate of analysis.
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.
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.
What is the amount of each ingredient inside the proprietary blend?
A blend total tells you nothing about whether any single ingredient reaches a dose used in research. Brands may decline — that answer is informative too.
Why is the turmeric / curcumin amount below the dose used in published research?
There can be good answers — a more bioavailable form, a different intended use. Ask for the reasoning and any data behind 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 |
|---|---|---|
| Quality-testing claim “…LAB TESTED…” | 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. No exact brand product page was available for a document check. 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. |
| Manufacturing claim “…GMP…” | Partly supported We looked for: the facility registration or certificate behind the claim | “GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check. |
| Benefit claim “Turmeric Curcumin Supplement 95% Curcuminoids 1950mg with Organic Turmeric & BioPerine Black Pepper Extract for Best Absorption, Natural Vegan Joint Support, Non-GMO, Bot” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Ingredient evidence exists; on dose: label claims 150 mg/serving — below the range commonly used in research (studies typically use 500–2,000 mg/day of curcuminoids). |
“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 |
|---|---|---|
| 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.

Related research & consistency
turmeric / curcumin — NIH NCCIH — Turmeric · PubMed search: curcumin bioavailability piperine · WebMD: turmeric · ClinicalTrials.gov — 286 registered studies
ℹ Dosage: label claims 150 mg/serving — below the range commonly used in research (studies typically use 500–2,000 mg/day of curcuminoids).
ℹ Use pattern in research: plain curcumin absorbs poorly — most positive trials pair it with piperine (black pepper) or a bioavailability-enhanced form.
