The evidencejudges the product.

Each product here sits beside the evidence that judged it: its full label, its testing, each ingredient’s findings, and its price, with no account needed to see any of it.

the independence ruledecision D6

Evidence strength never depends on whether we sell the product.

  1. 01We list our own label against the bar of evidence and quality below, and each product’s page shows how it fares.
  2. 02Our own label’s evidence is judged by the same public rules as every other product’s, and its page says it is ours.
  3. 03Every referral link says so where it sits, and what we earn from it.

the bar

Four tests, the same for every product.

A product that has not met all four cannot be bought here.

  1. 01Full labelEvery ingredient and its amount per serving. A blend that hides its amounts fails.
  2. 02TestingThird-party testing, or a certificate of analysis for the lot.
  3. 03EvidenceEach ingredient’s findings, with the evidence strength the graph computes. The threshold is not published yet.
  4. 04Open priceThe price is on the page without an account.

how we are paid

Said where it happens.

referral

Most products here are other companies’. If you buy through our link, the retailer pays us a fee. The link says so where it sits, with what we earn, and again before you leave.

our own label

We also sell our own, made and shipped for us by a supplier. Its page says it is ours and what we earn, and its evidence is judged by the same rules.
