Every result card shows the same five-segment bar. Each level below matches the color of that segment.
Level 1: Laboratory Research
Observed in cells, tissue, or computational models only.
Level 2: Animal Research
Studied in animal models; results often do not transfer to people.
Level 3: Early Human Research
Human research
Small, early-stage, or uncontrolled studies in humans.
Level 4: Controlled Human Studies
Human research
Randomized or otherwise controlled human trials exist.
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.
