Before you save a tip
Follow the claim back to its source.
The NIH's Office of Dietary Supplements recommends checking who is responsible for health information, the evidence behind it, its review process and its date. [1]
Find the person or team.
Look for the publisher, the writer and the reviewer, with their roles or credentials explained.
Follow the evidence.
Open the cited source. Separate the study's findings from the guide writer's opinion and any testimonial.
Check the review date.
Look for a dated review or update, then check whether the guide still reflects its source.
Sources for reading critically
- NIH Office of Dietary Supplements: How To Evaluate Health Information on the Internet. Publisher, evidence, reviewer and update-date checks.
- ACSM: 2026 resistance-training position stand. Healthy-adult scope and discussion of group-level findings and individualization.
The reading routes and topic groups are editorial ways to navigate this site. The source-checking questions are reading aids, and the ACSM example illustrates research scope.
