“GMP”
Evidence →“GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check.

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 400 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits inside that range.
0studied 200 mg–420 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
The panel lists 11 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits inside 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.
