Every ingredient shows its amount · 3 ingredients listed.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
Evidence and sources
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

Research behind the findings
Dose and research context
We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this 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.
0studied 8 mg–40 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
