Evidence →Ingredient evidence exists; on dose: label states 40 mg/serving — about 100% of the adult daily reference (adult RDA 8–11 mg; NIH sets 40 mg/day as the tolerable upper limit for adults). A single serving isn’t meant to supply a full day, so this is context, not a shortfall. Caveat: chelate and gluconate labels may state compound mass rather than elemental zinc.
Ingredient research can support context, but it is not a trial of this exact product.

“PARTY”
Evidence →No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. 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.

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 40 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.
