How we research

Every guide and review is built from primary sources: product labels, official product pages, government health agencies and peer-reviewed studies. We say clearly when evidence is weak, we never invent testimonials, and we update articles when prices or research change.

  • We link to the sources we used.
  • We separate what a manufacturer claims from what research shows.
  • We tell you when to talk to a doctor instead.
