How products move from consideration to publication
Our Review Methodology
How we select products, review evidence, reach a verdict, handle conflicts of interest, keep reviews up to date and correct mistakes — and how editorial judgement stays separate from affiliate revenue.
Our process
1. Selection
A product enters review because readers ask about it, it is widely sold in its category, or it makes claims worth checking — never because a brand paid for inclusion.
2. Evidence
We compare label claims with the relevant research for the specific ingredients, doses and outcomes involved.
3. Commercial check
We disclose affiliate status on the page. Commercial terms are never considered when we reach a verdict.
Our four evidence tiers
- Systematic reviews and clinical guidelines — the strongest basis for a claim.
- Randomised controlled trials of the specific ingredient, strain or dose.
- Observational and early-stage studies — useful signals, reported with caution.
- Mechanistic, lab or anecdotal evidence — never treated as proof of benefit.
Our eight review criteria
- Label transparency
- Strength of evidence for the stated use
- Formulation and dosing
- Safety information and suitability
- Value for money
- Ease of use
- Manufacturer quality information
- Customer support and returns
Updates and corrections
Reviews show a “last reviewed” date and are rechecked when formulations, prices or evidence change. If you believe something is inaccurate, contact us — substantive corrections are noted on the page.
Editorial verdicts vs. customer ratings: our verdicts are our own editorial assessment. They are not aggregated customer reviews, and we do not publish star ratings. Read our affiliate disclosure.
