How evidence levels work

How to read the evidence

Every result card shows the same five-segment bar. Each level below matches the color of that segment.

  1. Level 1: Laboratory Research

    Observed in cells, tissue, or computational models only.

  2. Level 2: Animal Research

    Studied in animal models; results often do not transfer to people.

  3. Level 3: Early Human Research

    Human research

    Small, early-stage, or uncontrolled studies in humans.

  4. Level 4: Controlled Human Studies

    Human research

    Randomized or otherwise controlled human trials exist.

  5. Level 5: Regulatory Review or Established Clinical Use

    Human research

    Reviewed by a regulator or established in clinical practice for a specific use.

Evidence is rated by claim—not popularity. More studies do not always mean stronger evidence.

A higher level describes research maturity. It is not a recommendation or endorsement.
