Check authorship and source quality

Look for named medical expertise, editorial review, publication dates and transparent organizational information. Reputable public health agencies and peer-reviewed clinical guidance are stronger starting points than anonymous posts. Treat promotional content that promises universal or immediate results with caution.

Understand what the evidence actually says

A single study may be preliminary, involve a small group or measure a surrogate outcome rather than meaningful health benefits. Check whether multiple independent sources agree and whether risks or limitations are discussed. Personal stories can be informative but cannot establish a treatment’s safety or effectiveness.

Apply information safely

General educational articles cannot diagnose an individual or replace a qualified clinician. Discuss medication changes, persistent symptoms and treatment choices with a healthcare professional who knows your history. Be especially careful with advice targeted at children, pregnancy or chronic illness.

Practical checklist

  • Identify a credible author and publication source.
  • Look for supporting evidence and stated limitations.
  • Discuss clinical decisions with a qualified professional.
