?Couldn’t verify independently2
“are proud that our products are manufactured in the USA, and we stand behind our customers'”
Evidence →“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
“with premium ingredients, our Zinc Picolinate supplement undergoes rigorous testing for purity and potency, ensuring top-notch quality you can rely”
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 50 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits above that range.

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