Common questions
Are Health Linear articles reviewed by a doctor?
No. We do not claim a medical reviewer. Articles are written by the Health Linear Editorial Team and every fact is checked against primary sources such as FDA prescribing information, DailyMed, NIH and peer-reviewed studies, which are linked so you can verify them yourself. Our editorial process page explains how this works. Always talk to your own doctor or pharmacist before changing a treatment.
How do you decide what to write about?
We prioritize topics readers are actively searching for and areas where we can offer genuine depth — medication comparisons and chronic condition management are our strongest areas of coverage.
Can I suggest a topic or report an error?
Yes — use the contact form to flag an outdated claim, a broken source link, or a topic you’d like covered. We review every report.
Are your calculators and screening tools safe to use?
They’re educational tools, not diagnostic or treatment devices — and we deliberately don’t build dosing or medication-conversion calculators, since those carry real risk without a licensed reviewer. See each tool’s own disclaimer for specifics.
