Zinc test results
Every zinc bottle a public source has named, with the lab numbers where a document printed them. We test nothing ourselves: each figure links to the document that printed it.
Records retrieved Oct 23, 2026 20 bottles 0 with a printed result
The short answer
From 4 public sources- None of 20 zinc bottles has a printed result for zinc in the public record. 2 have a printed panel for another ingredient only and 18 are certification listings with no numbers. A listing means a certifier named the bottle; it publishes no numbers.
Every zinc bottle
Grouped by what the public record is. A group heading opens that publisher’s page, filtered to this compound.

What is not here
ConsumerLab is not one of the sources: its reviews are paywalled, and nothing on this page is estimated from ConsumerLab. Anresco, InvaPharm, Eurofins appear as the laboratory on a Labdoor certificate, not as a publisher.
