Check the Source of an Online Health Claim
A confident headline is not enough. Check who wrote the claim, what evidence it uses, and when it was updated.
What this guide helps you doInspect the source, purpose, evidence, date, and privacy practices without making a diagnosis.
Who this guide is for
People who want to review a health claim before discussing it with a clinician.
Use the source document or official route that applies to your situation. This guide does not contact another person or verify external information.
Steps
Open the original source
Do not rely only on a screenshot or a repost.
Identify the provider
Find the organization and author. Check their role and contact details.
Check the evidence
Look for named studies, expert review, or links to primary evidence.
Check the date and purpose
Find the update date. Decide whether the page informs, sells, or collects data.
Ask a clinician
Use the claim to prepare a question. Do not change treatment based on this checklist.
Worked example
A post says that one food prevents a disease. The reader opens the linked article, checks its author and references, and asks a clinician about the claim.
Use your own source and details. The example is not a record about a real person or organization.
