FactoWiki Research Team

The FactoWiki Research Team is the role responsible for reading and summarising published scientific literature on supplement ingredients. It writes evidence reviews, ingredient guides and deep-dive articles, which are reviewed for publication by the FactoWiki Editorial Team. It does not hold or claim medical credentials.

What the Research Team does

How sources are selected

  1. Systematic reviews and meta-analyses of randomised controlled trials, including Cochrane reviews.
  2. Individual randomised, placebo-controlled human trials indexed in PubMed.
  3. Guidance and fact sheets from NIH (including the Office of Dietary Supplements), NCCIH and the FDA.
  4. Observational human studies, identified as such.
  5. Animal and laboratory studies, used only to explain a proposed mechanism and never as evidence of benefit in people.

Where reviews disagree, pages describe the disagreement and possible reasons — trial size, funding source, extract type, population — rather than selecting the most positive result. Industry funding is noted where it is apparent.

Ingredient evidence versus product evidence

Every evidence page keeps three questions apart: is there human evidence for the ingredient; was a benefit seen at a particular dose and form; and has a finished commercial product been tested. A result for one of these is not treated as an answer to the others.

How updates are handled

Evidence pages are revised when important new systematic reviews, large trials or regulatory safety information appear, or when a reader identifies an error. Dose figures are labelled as study doses, recommended intakes, upper limits, regulatory figures or commercial amounts so that updates do not blur these categories.

How corrections are handled

If a study is misdescribed or a citation does not match its source, the text is corrected or the citation removed, and the page’s updated date is changed. Report issues via the contact page.

How affiliate relationships work

Research Team pages — evidence reviews, ingredient guides and deep-dives — contain no affiliate purchase links. Where they mention products at all, they link to FactoWiki’s own desk-based reviews, not to sellers.

How conflicts of interest are avoided

Desk-based or first-hand?

Research Team work is desk-based literature review. The team does not conduct clinical trials, laboratory analysis or product testing.
