Evidence lens

Read as directional context, not settled clinical proof.

LimitedLimited evidence

Human clinical evidence: Not the primary signal

Mechanistic / preclinical: Mechanism mapped — GABAergic Neurotransmission Modulation · CNS Depressant Like Effects · Neurotransmitter Modulation

Research maturity: Theoretical / mechanistic research — Mechanistic or unresolved evidence is kept separate from established human outcomes.

Safety boundary: Safety note available — Kava/kavalactones are linked with sedation and liver injury concerns; avoid alcohol, sedatives, liver disease, and pregnancy.

How evidence grades work

Each grade reflects the strength and consistency of published human evidence — not marketing claims. Grades are based on study count, design quality, effect size, consistency, and recency.

Strong: Multiple RCTs, consistent direction, adequate effect size
Moderate: Some RCTs or consistent observational data in humans
Preliminary / Mixed: Animal or in-vitro only, or conflicting human data
Traditional / Theoretical: Traditional use only; no controlled human trials
