Common questions
Is Health Linear’s content medically reviewed?
Every article is checked against primary sources — FDA labeling, clinical trials, and peer-reviewed research — as part of our editorial process. See our editorial process page for exactly how that works.
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Yes — use the contact form to flag an outdated claim, a broken source link, or a topic you’d like covered.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.
