A credible explanation should help you see what a study can support—and where it stops. Start with the source itself, not only a summary, a screenshot or a product claim.
Identify the kind of evidence
| Source | Question to ask |
|---|---|
| Laboratory experiment | Was this studied in cells or another model? |
| Animal study | What prevents direct translation to people? |
| Human trial | Who participated, and what was measured? |
| Review article | Which underlying studies support its conclusion? |
| Product label | Is it the exact approved formulation? |
| Personal report | What other explanations cannot be excluded? |
Read beyond the headline
Look for the population, sample size, comparison group, duration, outcome measures and adverse events. A change in a laboratory marker is not necessarily the same as a meaningful improvement in health.
Follow the formulation
A compound name can appear in different formulations and routes of administration. Evidence about one version does not automatically cover another. Similar spelling or a shared nickname is not enough to establish equivalence.
Separate observation from causation
A reported event after exposure is important to investigate, but the timing alone may not establish its cause. Equally, an absence of reported problems in a small study does not prove safety.
A protocol is part of a study
Study schedules exist alongside eligibility criteria, monitoring, stopping rules and clinical oversight. Copying a schedule without that context does not recreate the study.
Make a small evidence record
- Exact substance and formulation
- Source title, link and publication date
- Study type and participant or model details
- What was measured and what was found
- Limitations, adverse events and unresolved questions
The PubMed database can help you find biomedical literature. A search result is a starting point for reading, not an endorsement of a claim.
