Does the marketing hold up?

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 210 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 1 g of prebiotic fiber (inulin-type) per serving. Studies we found used 3 g–10 g a day, so this sits below that range.

0studied 3 g–10 g

Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
