Five questions.
Same rubric. Every time.

Does each active ingredient meet the minimum effective dose from peer-reviewed clinical trials? We compute per-ingredient doses from proprietary blends using maximum possible allocation. A product cannot score above 7.0 if any primary active is sub-clinical.

Is the form of each compound the most bioavailable studied? Magnesium glycinate scores higher than oxide. Creatine monohydrate higher than ethyl ester. We use pharmacokinetic literature — not manufacturer claims.

Is the product independently verified for label accuracy, heavy metals, and banned substances? NSF Certified for Sport, Informed-Sport, USP, and equivalents accepted. Manufacturer COAs alone score zero.

What does one effective dose cost? We calculate cost-per-clinical-serving — not cost-per-label-serving, which often uses sub-clinical doses — and compare within category.

Does the label overstate effects? Misrepresent evidence? Use structure-function claims that exceed what the literature supports? A product loses points for every instance of unsupported claim.
