How it works

Kava is primarily used for its potent anxiolytic properties, with multiple clinical trials supporting its efficacy in reducing generalized anxiety. It is also frequently used as a social lubricant and sleep aid due to its ability to promote relaxation without significant cognitive impairment.

Kavalactones modulate GABA-A receptors and inhibit the reuptake of noradrenaline and dopamine, while also providing mild monoamine oxidase B (MAO-B) inhibition.

Safety

  • Potential for liver toxicity, particularly when using non-noble varieties or ethanol-based extracts.
  • Do not combine with alcohol or other CNS depressants due to extreme potentiation of sedative effects.
  • May cause drowsiness; avoid driving or operating heavy machinery after consumption.
