Can I Take ashwagandha with l-theanine?

SUMMARY:

Taking ashwagandha together with L‑theanine can have additive calming/sedative effects; for most people this combination is generally tolerated but may increase drowsiness or lightheadedness.

ADDITIONAL NOTES:

Both are non-prescription supplements that promote relaxation—ashwagandha via adaptogenic/CNS‑calming effects and L‑theanine via promotion of relaxation and reduced stress. Combining them can increase sedation (drowsiness, slowed reaction time) and may unmask lightheadedness or dizziness. Use caution with driving or operating machinery, avoid adding other sedatives (including alcohol, benzodiazepines, sleep medications), and consult a healthcare provider if you take blood‑pressure medications, sedatives, antidepressants, or have medical conditions (pregnancy, breastfeeding, or serious illness).
