This policy sets out what every article on HealthDiseases.org must do, and what none of them may do.
Education first
Every important health topic is written to be useful on its own. A reader should be able to read a condition guide, a symptom page or an ingredient profile and come away better informed without clicking anything commercial. Medical information always comes before any discussion of supplements.
Three kinds of page
Every page on this site belongs to one of three categories, shown as a label at the top of the article:
- Educational article — contains no product recommendations and no affiliate links. Our page templates for these articles have no slot for a product, so one cannot be added by accident.
- Educational article with supplement context — discusses ingredients or supplement categories and may mention a single commercial product, with disclosure.
- Supplement research — evaluates commercial products and contains affiliate links, disclosed on the page.
The large majority of pages are in the first category.
Sourcing
Health claims are supported by references to government health agencies (NIH, CDC, FDA, NCCIH, MedlinePlus, NIDDK, NHLBI, NINDS, USDA and equivalents in other countries), systematic reviews and meta-analyses, randomized controlled trials, and major professional medical organizations.
We do not use affiliate websites, supplement sellers or content farms as sources for health claims. We do not invent studies, and we do not cite a study we have not been able to locate.
Language
We write for roughly a grade 7–9 reading level where the subject allows, explain technical terms, and use short paragraphs. We avoid filler phrases and do not use the same template paragraph across many pages with only the topic name changed.
We use conservative language for supplement effects: "may support", "has been studied for", "evidence for individual ingredients varies". We do not say that a supplement cures, treats, reverses or eliminates a disease, replaces medication, or is clinically proven to do something the evidence does not show.
Product facts
Prices, guarantees, doses, certifications and manufacturer details are checked against the product label and the seller's own page. Where a fact cannot be confirmed it is marked "not independently verified". We do not write customer reviews, testimonials or ratings on behalf of customers, and we do not display aggregate star ratings that are not backed by a real dataset.
Uniqueness
One topic, one page. If two pages would answer nearly the same question, we publish one and consolidate. We do not create pages simply because a keyword exists.
Review and updates
Every article shows who wrote it, who fact-checked it, the date it was last reviewed and the date it was last updated. Pages are re-checked on a rolling schedule and whenever guidelines change. See how we research and our corrections policy.
