How we write

Evidence first. Marketing second. Clearly separated.

Lio makes a flavoured air device, so we have a stake in this topic. That's why every guide shows who wrote it, which sources it uses and when it was last checked.

  • Named author. Every guide is signed.
  • Sources you can check. Every claim links to the study or source behind it.
  • No cure claims. Lio is not a medical device or a smoking cessation aid.
  • Corrections in public. If we get something wrong, we fix it and say so.
