How to evaluate a source

  1. Identify who published it and whether the organization has relevant expertise.
  2. Check the publication or review date and whether the page has been updated.
  3. Look for methods, references, limitations, and a clear distinction between evidence and opinion.
  4. Confirm whether the information applies to your country, region, age group, and health context.
  5. For personal decisions, bring the source to a qualified clinician, pharmacist, lawyer, or public authority.
