How we choose
This page sets out the rules we hold ourselves to: where our health information comes from, how often it's checked, and what a company has to be before we'll send you to it.
Effective date: 10 September 2026. Last reviewed: 10 September 2026.
1. Editorial independence
Commercial partners have no input into navigator logic, question wording, results, or the order in which options appear. Free and publicly funded routes are always shown before paid options. Partners cannot pay for placement, and we don't accept payment for reviews or "sponsored content" that isn't clearly labelled as such.
2. Sources we write from
Navigator content and thresholds are written against current published guidance from: NHS and NICE (UK); CDC, USPSTF, NIH Office of Dietary Supplements and FDA labelling (US); Health Canada and Canadian Task Force on Preventive Health Care (Canada); and peer-reviewed clinical literature. Where guidance differs between countries, we show the version for the country you select. We don't use anecdote, influencer content or manufacturer marketing as a source.
3. Review process
- Every navigator is reviewed against its sources before publication and at least every 12 months.
- Emergency and crisis numbers are checked every 6 months.
- Threshold changes in official guidance (for example prescribing criteria, screening ages, supplement dose advice) trigger an out-of-cycle review.
- Clinical review: [name and credentials of reviewing clinician; or "in progress" — see About].
4. Health claims policy
We do not claim that any product, test, service or supplement diagnoses, treats, cures, mitigates or prevents any disease. We describe what a test measures, what a service offers, and what published guidance says — nothing more. Partner marketing language is not reproduced on this site. This policy is applied to all content, including future articles and social posts.
5. Partner inclusion criteria
A company is only linked to if it meets all applicable criteria below. We check at onboarding and re-check annually or on any public regulatory action.
| Category | Minimum requirements |
|---|---|
| At-home testing | Samples analysed by accredited laboratories (CLIA-certified in the US; UKAS-accredited in the UK; provincially licensed in Canada). Results reviewed or explained by a clinician. Clear guidance on what to do with abnormal results. |
| Telehealth and medical weight-loss | Prescribing by clinicians licensed in the patient's jurisdiction (state licensure; CQC registration and GPhC-registered pharmacy in the UK; provincial college registration in Canada). Medical history taken before prescribing. Follow-up offered. FDA-, Health Canada- or MHRA-approved medicines; services offering only unapproved or compounded products are excluded. |
| Therapy platforms | Therapists licensed or accredited in the user's jurisdiction and verifiable. Clear crisis escalation policy. Published privacy practices for session data. |
| Supplement retailers and brands | Third-party testing (USP, NSF, Informed Choice or equivalent) on own-brand products. No disease-treatment claims in marketing. Complies with FDA DSHEA / UK and EU food-supplement rules. |
6. What we exclude
- "Miracle", "detox", "cure" or rapid-weight-loss products and any nutraceutical marketed with disease claims.
- Services that prescribe from a questionnaire alone with no history, no follow-up and no clinician contact.
- Unvalidated tests (for example IgG food-sensitivity panels, hair mineral analysis) and "adrenal fatigue" products.
- Sweepstakes, lead-generation forms that harvest personal data, or any offer that requires payment details before disclosing price.
- Any partner subject to an unresolved regulatory enforcement action.
