Can you take Kava and Melatonin together?
Kava is a significant sedative on its own. Adding melatonin may cause excessive drowsiness and prolonged grogginess.
Severity
Caution
Evidence
limited
Timing
Before bed, reduced doses.
How it works
Kava kavalactones enhance GABAergic inhibition and block sodium channels; melatonin activates MT1/MT2 circadian receptors.
No published studies on this specific combination. Kava's sedative, anxiolytic, and muscle-relaxant properties are well-established. The additive effect with melatonin is expected based on their pharmacology.
What to do
Reduce doses of both if combining. Take 30–60 minutes before bed only. If kava alone is sufficient for sleep, melatonin may be unnecessary.
