“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.

Nutrabio Zinc Chelate (30mg)
Checked against public sources on August 7, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Testing claimed — documentation not found. The observed listing claims third-party testing without naming a lab or certifier. No product-bound report is saved, so the claim cannot be verified as stated. …
“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 confirmed1
Ingredient research can support context, but it is not a trial of this exact product.
?Couldn’t verify independently2
“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.
What is worth knowing.
Headlines first. Open evidence only when you want the source trail.
Registered owner records: NUTRABIOCOM, INC. · NutraBio Labs, Inc.
The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.
Evidence and sources

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.

Dose and research context
The label amount is shown beside the range used in the linked ingredient studies.
Zinc
30 mg per serving — within the 8–40 mg/day used in the linked studies.
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.
