Checked against public sources on July 26, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
FDA recall appears in this brand's history. An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
Is the dose real?✓Listing and panel agreeboth say 1,000 mg of Curcumin Extract
What a serving costs$0.70per serving, at the checked price
Is it tested?No testing claim made
Who’s behind it?USPTO lists 2 owner recordssame brand name, more than one registrant — we don’t choose between them
Is it the real thing?✓Barcode matches outside records
Trouble on record?Brand history — not this product
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

FDA recall appears in this brand's history
An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
Evidence and sources
This recall is not about the product on this page. QUTEN RESEARCH INSTITIUTE LLC recalled a different product on December 16, 2025. FDA lists that case as Ongoing. The recalled item was “Qunol, Extra Strength Turmeric Capsule, 1000mg ,HDPE bottle with cap, BIO7771 120 count…”

Registered owner records: Quten Research Institute, LLC · Quten IP Holdings, LLC
The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.
Evidence and sources
USPTO returned multiple live supplement-class records for the exact brand wordmark: Quten Research Institute, LLC, Quten IP Holdings, LLC. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.

Every ingredient shows its amount · 5 ingredients listed.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
Evidence and sources
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

The barcode identity checks out · 850184008091.
The barcode matches, so we are checking the right product rather than a look-alike.
Evidence and sources
The brand's store lists this exact barcode as “Liquid Turmeric Curcumin, 1000 mg” (variant: 40 Servings | 20.3 Ounces) — identity confirmed across retailer listings.
Locked evidence record →Open the full source-linked findingChecks outCan you trust the review pattern?
Reviews rose from 1,337 to 1,372 between January 31 and May 19, 2026 — no sudden jump.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 1,337 to 1,372 between January 31 and May 19, 2026. The largest rise inside any single 30-day window was about 11, so the count moved in steps rather than in one burst.

Research behind the findings
Dose and research context
We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.
Background reading
What the research says about these amounts
Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.
The panel lists 1 g of turmeric / curcumin per serving. Studies we found used 500 mg–2 g a day, so this sits inside that range.
0studied 500 mg–2 g
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.

The observed listing and exact brand page repeat 1000 mg. That confirms cross-page consistency of the published claim, not the product contents.
