Start with a focused question
Identify the exact product and proposed benefit. Then ask whether the study actually addresses both. Keep the publication date and funding information in your notes so a later comparison has some context.
Record what the paper reports
Use a consistent worksheet instead of collecting impressive phrases.
- Participants and sample size.
- Product and comparison condition.
- Outcome and measurement period.
- Reported uncertainty and limitations.
- Funding and independent replication.
Leave space for an uncertain answer
FTC guidance explains that publication does not necessarily make research conclusive evidence of a product’s effect. A careful reading may support only a limited conclusion. Avoid turning a tentative result into advice for an individual health situation.
