    "methodology": "Claims collected from each brand's public product page, marketing copy, and feature bullets during Q2 2026. Each claim was matched to the strongest available peer-reviewed evidence (Cochrane systematic reviews preferred; PubMed-indexed RCTs and meta-analyses next; observational studies last). Evidence grades follow Cochrane GRADE conventions (high, moderate, low, very low). Verdicts: 'supported' (claim matches direction and magnitude of evidence), 'partially supported' (direction correct, magnitude overstated or context-dependent), 'unsupported' (claim is not supported by current evidence base), 'contradicted' (best available evidence points the other direction). Brand transparency score is a 0-100 composite of (a) presence of a citations or evidence section on the product page, (b) accuracy of any cited studies, (c) absence of unsupported superlatives (cure, eliminate, guaranteed), and (d) qualified language on contested claims.",
