The public sources did not settle the marketing promises on this label.

The label amount is shown beside the ranges used in the linked ingredient studies.
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 0.7 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits below that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
