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…

“Vegetarian Caps Per Bottle 30 mg of Zinc (from Zinc Picolinate) Per Serving 120 Servings of Zinc Picolinate Per Bottle Non-GMO, Gluten Free,…”
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
“PARTY”
Evidence →No named laboratory or lot-specific certificate was found for this exact product. The exact brand page repeats a testing claim but names no issuer. 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.

CheckedIs the label honest?
Listing claim matches the Supplement Facts panel
The label promise and the Supplement Facts amount agree.
Evidence and sources
The listing claims 30 mg; the photo-read Supplement Facts panel shows Zinc (as zinc picolinate) at 30 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.

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.

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 30 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits inside that range.

Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
