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 2.5 g of creatine monohydrate per serving. Studies we found used 3 g–5 g a day, so this sits below that range.
0studied 3 g–5 g
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 450 mg of fenugreek per serving. Studies we found used 500 mg–600 mg a day, so this sits below that range.
