How this ranking is built
| Component | Weight | Basis |
|---|---|---|
| Dose integrity | 40% | Share of key actives meeting clinical thresholds, minus a blend penalty |
| Value | 30% | Cost per fully dosed serving, ranked against the category |
| Label disclosure | 15% | Share of the actives the label puts a number against. An amount hidden in a proprietary blend, or simply not stated, scores zero here rather than counting as missing data — non-disclosure is a fact about a label, not an absence of one |
| Consensus | 15% | Buyer rating shown on the brand’s own product page (read from the page, or from the review service that draws its stars; source-linked), minimum 25 reviews, re-read within the last 30 days, count, source and capture date printed on every product page |
A missing component is never scored as zero. Its weight is redistributed across the components that exist, and the page says which one was omitted.
