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.
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 450 mg of magnesium per serving. Studies we found used 200 mg–420 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.
