How We Research and Use Sources

Source order

1. FDA medication guides, safety communications, and approved labeling
2. Government and professional medication-safety guidance
3. Systematic reviews and high-quality pharmacoepidemiology research
4. Current manufacturer labeling used only for verified product-specific facts

How claims are handled

We separate established guidance, research findings, practical reader steps, and unknowns. A seller, organization, or press release may document what that party says; it does not independently prove the claim.

Freshness

Health, safety, legal, regulatory, and school-policy information can change. Pages should show a review date and be checked again when guidance or the underlying evidence changes.

What we never invent

We do not invent hands-on testing, credentials, interviews, institutional affiliations, quotations, study results, or personal outcomes.
