Every collection is a set of filters over the researched library — never a paid placement, and never a ranking of one brand above another.

Our process & standards

  • Every product here was researched against manufacturer, regulatory, and retailer sources, with the ingredient list captured as printed.
  • Sources are used in that order — the manufacturer first, then regulatory records, then retailers — and a claim only counts as the brand’s when the brand is the one making it.
  • Formula readings are derived from that ingredient list by a fixed rule set — the same one the consultation uses to match products to people.
  • Cost per ounce is computed from dated price observations and compared only against products of the same type and size class.
  • We sell nothing here. Nothing on these pages is paid placement, and no brand can buy a position, a badge, or a chip.
