You can take it at either time depending on your goals.
If you're looking for stress support during the day, take it in the morning with breakfast.
If you want help with sleep and relaxation, take it 1-2 hours before bedtime.

Most people start noticing some benefits within the first week, like feeling calmer or sleeping slightly better.
However, the full stress-reducing and energy-balancing effects typically develop over 4-8 weeks of consistent daily use.

While ashwagandha promotes relaxation, it shouldn't make you drowsy when taken as directed.
It's an adaptogen, which means it helps balance your energy - calming you when you're stressed but not making you sleepy when you need to be alert.
If you do feel drowsy, try taking it in the evening instead of morning, or consider if you might be taking too much.

Ashwagandha is generally safe for daily use for most healthy adults.
However, it's recommended to take breaks after 2-3 months of continuous use.

Always consult with a healthcare provider before starting any new supplement, especially if you're pregnant, nursing, or taking medications for thyroid or immune conditions.
