Does the marketing hold up?
The label’s 220 mg reads 4× larger than the zinc on the panel. Salt weight, not the actual mineral. 220 mg is the weight of the zinc sulfate compound. The actual zinc in it is 50 mg. You are getting 50 mg of zinc per serving.

Is it the real thing?✓Barcode matches outside records
Trouble on record?✓No recalls found
“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.

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.
