Editorial Methodology

Our process is designed to separate facts from marketing claims and direct evidence from indirect evidence.

1. Verify the product

We identify the current product, company, formula, Supplement Facts, serving information, directions, price, seller, guarantee and availability.

2. Classify claims

Information is treated as a verified product fact, seller claim, independent evidence, consumer report or unverified claim.

3. Evaluate evidence distance

We give more weight to exact finished-product human trials than to comparable formulations, ingredient studies, mechanistic evidence, anecdotes or seller claims.

4. Examine limitations

We consider dose differences, formulation differences, study size, population, conflicting sources and lack of finished-product testing.

5. Recheck commercial facts

Price, packages, shipping, subscriptions, guarantees and availability are time-sensitive and should carry a real last-checked date.

6. Correct material errors

Reliable newer information should replace outdated material rather than preserving an old statement simply because it previously ranked.
