Ashwagandha can cause morning grogginess—often called an "ashwagandha hangover"—due to dose size, timing, individual sensitivity, formulation, and interactions with other supplements or medications. To minimize sluggishness, work with your doctor to adjust your dosage, shift timing earlier in the evening, try a different formulation, implement cycling patterns, and improve sleep hygiene. Personalized monitoring and testing help you enjoy ashwagandha's benefits without waking up foggy.

Take a free, instant, online symptom check to better understand what's driving your fatigue and confidently navigate your next steps.
