Can you take Ashwagandha and Kava together?
Both reduce anxiety and promote relaxation through GABAergic pathways. The combination may cause significant sedation and impair driving ability.
Severity
Caution
Evidence
limited
Timing
Evening only, low doses if combining.
How it works
Kava acts directly on GABA-A receptors and sodium channels; ashwagandha modulates cortisol and has GABAergic activity.
The overlapping GABAergic mechanisms make additive sedation likely. Kava also carries hepatotoxicity concerns with long-term use, which ashwagandha does not share. Monitor liver health if using kava regularly.
What to do
If combining, use low doses and restrict to evening use only. Do not drive or operate machinery. Consider whether both are necessary — ashwagandha alone may provide sufficient anxiolytic effect.
