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?Panel read — dose not verified4 ingredients listed; no advertised amount we could confirm against them
What a serving costs$0.50per serving, at the checked price
Is it tested?NSF seal printed on the labelwe read it off the package photo; not confirmed in NSF’s registry
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.

The checks, one by one
The public sources did not settle the marketing promises on this label.
◐Partly confirmed2
“wellness supplement is made in GMP-certified facilities, and our purity and potency testing includes independent third-party”
Evidence →“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.
?Couldn’t verify independently1
“wellness supplement is made in GMP-certified facilities, and our purity and potency testing includes independent third-party”
Evidence →No named laboratory or lot-specific certificate was found for this exact product. A related brand page names no testing issuer and links no product-bound report; its UPC is not published. 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.

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. Swanson Health Products, Inc recalled a different product on March 4, 2022. FDA has since closed that case. The recalled item was “Swanson Ultra: Vitamin B12 Methylcobalamin High Absorption 60 serving per container, Item Code…”

Registered owner records: Swanson Health Products, Inc. · Swanson Health Products, Incorporated
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: Swanson Health Products, Inc., Swanson Health Products, Incorporated. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.

Every ingredient shows its amount · 4 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.

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 prebiotic fiber (inulin-type) per serving. Studies we found used 3 g–10 g a day, so this sits below that range.
0studied 3 g–10 g
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
