The Afera Encyclopaedia is an evidence-graded reference published by Camden Medicals Limited. It is written in editions, and each edition lives on the site its readers already use.
The editions
- Health edition, here on camdenmedicals.co.uk: the ingredient encyclopaedia. Each entry covers what an ingredient is, what UK-authorised health claims allow, what the evidence shows, and what to look for when buying.
- Careers edition, on verifera.co.uk: professional registers, credentials and career pathways, with editions for the Netherlands and Portugal on verifera.eu.
How entries are written
- Sources on the page. Every entry lists the sources it relies on, with numbered citations in the text.
- Official guidance first. Where the NHS, NICE or another national body has published guidance, the entry shows it first. Our own appraisal of the research sits beneath that guidance, never above it.
- Graded, not guessed. Health claims on an entry carry a grade for the strength of the published evidence. How we grade the evidence explains the method and where it does not yet reach.
- Dated reviews. Each entry shows when it was last reviewed and when its next review is due.
- Corrections. Every entry has a link to report a concern or a mistake to our editorial team.
Who publishes it
Afera is the editorial property of Camden Medicals Limited, a UK supplement retailer. We have a commercial interest in some of the ingredients described in the Health edition. We declare it on every entry, and our editorial process forbids adjusting copy to favour our own products. Read our editorial policy.
Afera is information, not medical advice. Talk to your pharmacist or GP before starting any supplement, especially if you take prescribed medicines, are pregnant or breastfeeding, or have an existing condition.
Former name
Until October 2026 the encyclopaedia was called the Verifera Encyclopaedia. Verifera is now the name of our sister business, Verifera Recruitment.
