Background
- Nine years writing and editing consumer health explainers before going independent
- Reads and cites primary sources only: peer-reviewed literature, ACOG and NAMS clinical guidance, NIH and NIA material, and the STRAW+10 staging criteria
- Not a physician, nurse, dietitian or therapist, and says so on every page
- Re-reads and re-dates every guide on a fixed review cycle rather than leaving old advice standing
- Takes no vendor sponsorship, no supplement partnerships and no telehealth referral fees
