Checked against public sources between July 22 and August 31, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Package and trademark records name different responsible entities. The package says manufactured for: Nutrifair, 4742 42nd Ave Seattle, WA 98116. USPTO names FINEST VITAMINS, LLC as the exact wordmark owner. That can be a normal distributor, manufacturer, or licensing…
“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.
The public sources did not settle the marketing promises on this label.
“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.
Ingredient research can support context, but it is not a trial of this exact product.
“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
No named laboratory or lot-specific certificate was found for this exact product. The exact brand page names no testing issuer and links no product-bound report. 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.
We looked and found no public proof. That does not count against the product.
Headlines first. Open evidence only when you want the source trail.
The barcode matches, so we are checking the right product rather than a look-alike.
The brand's store lists this exact barcode as “Berberine HCI 1200mg with Organic Ceylon Cinnamon - 120 capsules” (variant: Default Title) — identity confirmed across retailer listings.
