How we check a label

  1. We find every public test. Published lab results and certifier records, such as NSF. We date each search.
  2. We check each number against its source. We read the original report, and we count results one way: met the label means at least 90% in every tested batch.
  3. We pick by a written rule. Proof of the dose first, then the lowest cost per real dose. Brands can’t pay to be included, ranked or picked.
