Does the marketing hold up?
Package and trademark records name different responsible entities. The package says manufactured for: nutricost, 351 E 1750 N, Vineyard, UT 84059. USPTO names eSupplements, LLC as the exact wordmark owner. That can be a normal distributor, manufacturer, or licensing…

Is it the real thing?✓Barcode matches outside records
Trouble on record?✓No recalls found
“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.

◐Partly confirmed2
“PARTY”
Evidence →A testing body is named on the brand page (NSF), but we found no lot-specific certificate of analysis.
“in an NSF Certified, GMP Compliant, FDA Registered”
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.

CheckedIs the label honest?
Every ingredient shows its amount · 3 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 50 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits above that range.
0studied 8 mg–40 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
