How we rank sellers

Sellers are ranked by what they prove, not by what they pay us: lab proof first, then FDA letters, then labels.

Every seller we have checked is listed, whether or not it pays us. We check each one on the same points, and we show what we found, with the date we checked. We add sellers as we check them.

What decides the order

  1. Lab proof comes first, in the order of the labels below. A report you can see beats one sent by email, and either beats a claim with no document.
  2. An FDA warning letter moves a seller down. It stays listed, with the letter shown next to its name.
  3. If everything else is equal, a seller whose own label says “not for animals” ranks lower, and it gets no link.
  4. Sellers level on all of these are listed by name.

Lab test labels we use

Whether a seller pays us is not part of the ranking. No seller yet shows a report for the batch you would get.
