This policy sets the rules for everything we publish. It covers sources, independence, AI tools, corrections and updates. If a page on this site breaks one of these rules, we want to hear about it.

Who is responsible
Ellis Warren, Lead Reviewer, writes and approves our reviews and guides. Ellis is a researcher and editor, not a medical professional. Our content is for general information only. It is not medical advice. See the medical disclaimer.
What sources we use
We favor primary and official sources. In rough order of weight:
- Human clinical trials and systematic reviews in peer reviewed journals.
- Government sources such as the NIH Office of Dietary Supplements, the FDA and MedlinePlus.
- The product’s own label, sales page, terms and refund policy.
- Public records such as FDA warning letters, recall notices and FTC actions.
We do not treat brand press releases, paid reviews or customer testimonials as evidence that a product works. When we quote a brand claim, we label it as a claim.
What our “Lab” name does and does not mean
We do not run lab tests, and we do not buy or test products ourselves. “Lab” refers to our structured desk method: reading labels, studies and public records in the same order for every product. Our full steps are on the how we review page.
Independence from commissions
We earn affiliate commissions when readers buy through some links. That money keeps the site free. It does not buy coverage or a softer review.
- Brands cannot pay to be reviewed, to see a review early or to change one.
- We apply the same method whether or not a product has an affiliate program.
- We report weak evidence, hidden doses and strict refund terms even on products that pay us.
- We do not use scores, star ratings or verdict labels.
More detail is on our affiliate disclosure page.
How we use AI tools
AI tools help us draft and organize our work. We use them to sort research notes, outline pages, suggest plain wording and spot gaps in a draft. A human editor checks every fact and source before publishing. That check covers each dose, price, refund term, study finding and link. If an AI tool suggests a claim we cannot trace to a real source, we cut it.
AI tools do not decide what we review, what evidence grade an ingredient gets or what goes into the final page.
Corrections
We fix errors as soon as we confirm them. Small fixes, such as a typo, are made quietly. When a fix changes a fact a reader may have relied on, such as a dose, price or refund term, we note the change and the date at the end of the page.
To report an error, email [email protected] or use our contact page. Please include the page link and what you think is wrong.
Updates
Supplement formulas, prices and terms change often. We recheck published reviews on a regular cycle and whenever a reader or brand flags a change. Each page shows the date it was last updated.
Language and claims
We write in short, plain sentences. We avoid words that promise results. We do not say a supplement cures, treats or prevents any disease. When the evidence is thin, we say so in plain terms.
