The Foundation
Our commitment to accuracy
Health decisions deserve better than guesswork. Every piece of content on Numan is built on clinical evidence, written with objectivity, and reviewed by qualified medical professionals before it ever reaches you.
Our content follows the principles of clinical evidence, sourcing data from peer-reviewed journals, academic institutions, and government health bodies (e.g., NHS, NICE, MHRA). This isn't a checkbox exercise. It's the foundation of how we operate.
Clinician-reviewed
Audited by GMC-registered doctors and GPhC pharmacists.
Objective
Education and commercial content are always separated.
Regularly reviewed
Audited against the latest UK medical standards.
Process
The Numan Clinical Review
Every piece of content follows a five-stage lifecycle.
1. Ideation
Topics are identified through patient needs, clinical data, and emerging medical trends.
2. Drafting
Written by health writers or clinical experts with subject-matter knowledge.
3. Clinical review
Checked by a GMC-registered doctor or GPhC-registered pharmacist.
4. Fact-checking
All data points, statistics, and citations are independently verified against source material.
5. Final approval
Signed off by the appropriate clinical team before publication. No article bypasses this step.
Sourcing & citation standards
Not all sources are equal. We operate a tiered sourcing framework that prioritises primary research and high-authority medical databases over secondary reporting.
Primary sources
Original peer-reviewed studies, randomised controlled trials, and systematic reviews published in recognised journals.
Institutional guidelines
We reference guidance from NHS, NICE, MHRA, WHO, and equivalent regulatory bodies.
Expert commentary
Authoritative analysis from recognised specialists, used only to contextualise — never as standalone evidence.

The medically reviewed badge
When you see this badge at the top of an article, it means a named, qualified clinician has personally vetted the content for medical accuracy.
What this means:
The reviewing clinician is a GMC-registered doctor or GPhC-registered pharmacist with relevant clinical experience.
Their name and credentials are displayed alongside the badge, linked to their full Expert Profile on Numan.
The review date is shown so you always know how recently the content was verified.

What we don't use
Anecdotal evidence, unsourced claims, non-peer-reviewed opinion pieces, and content from sources without verifiable credentials. If we can't trace a claim back to robust evidence, we aim not to publish.
Content maintenance & freshness
Medical guidelines evolve. New research emerges. Regulatory positions shift. What was accurate a year ago may no longer reflect best practice, and, for health content, that distinction matters.
Numan performs Annual Clinical Audits on all evergreen content. Every article, treatment page, and clinical guide is reassessed against current UK medical standards, with updates applied where the evidence base has moved.
Transparency
Independence & transparency
Numan is a healthcare company. We sell treatments. That context matters and we don't hide from it. What we do is draw a clear, visible line between clinical education and commercial recommendation.
Editorial independence
Clinical and editorial teams lead on health content. Medical accuracy and editorial direction aren't shaped by commercial priorities.
Clear labelling
Product pages and treatment recommendations are always identifiable. You'll never mistake a commercial page for an educational article.
Built for trust
Our writers and reviewers focus on accuracy, not performance. Their job is to inform, not to sell.
