Editorial Methodology

Last reviewed: September 25, 2026

Every effectiveness or safety claim on this site is placed into one of these categories, and labeled accordingly wherever it appears:

CategoryWhat it means
Verified product factConfirmed directly from the manufacturer's current official checkout or packaging (e.g., price, guarantee length, ingredient list).
Seller claimStated by the manufacturer but not independently verified by us (e.g., "no auto-ship subscription").
Independent evidenceA peer-reviewed, published study we traced back to its original source — tagged by strength (strongest / moderate / weaker) based on sample size, study design, and how closely it matches the actual product (same ingredient vs. same route/dose vs. finished product).
Consumer reportGeneral patterns reported for this product category — never a fabricated individual quote.
Unverified claimSomething we found repeated elsewhere but could not confirm from a primary source — flagged explicitly, not repeated as fact.

Evidence Distance

Ingredient-level evidence is never presented as proof that the finished product works. We rank evidence on a distance scale: an exact finished-product trial would be strongest; a trial on the same ingredient at the same dose and delivery format is next; a trial on the same ingredient at a different dose or format (which describes most of what's cited for LeanBiome) is weaker still; animal/lab evidence and anecdote are weakest. Where a claim sits on that scale is stated directly on the page it appears on.
