You've probably seen the amber-colored jars sitting on your friend’s kitchen counter or spotted the "mood-boosting" gummies next to the checkout at Whole Foods. Ashwagandha is everywhere. It's the crown jewel of Ayurvedic medicine, a plant technically known as Withania somnifera, and people are obsessed with it. But after you buy the bottle, a nagging question usually hits: what time of day should you take ashwagandha to actually feel something?
Timing matters.

If you swallow it at 8:00 AM with your espresso, you might have a totally different experience than if you pop it right before brushing your teeth at night. It isn’t like a stimulant that hits your bloodstream in twenty minutes, nor is it a sedative that knocks you out cold. It’s an adaptogen. That means it works with your body's HPA axis—the hypothalamic-pituitary-adrenal axis—to manage how you react to stress.
Honestly, the "best" time is mostly about what you're trying to fix. Are you a vibrating ball of nerves during your 2:00 PM Zoom calls? Or are you staring at the ceiling at 2:00 AM wondering why your brain won't shut up? Your personal biology dictates the schedule.
The Case For Morning Dosing: Crushing Daily Stress
Taking your supplement early can be a game-changer for people who deal with "morning dread." You know that feeling. Your eyes open, and within seconds, your brain has already listed seventeen things that could go wrong today.
When you consider what time of day should you take ashwagandha, the morning is ideal if you want a buffer against the world. It doesn't make you drowsy in the way a Benadryl does. Instead, it subtly blunts the sharp edges of cortisol.
A study published in the Indian Journal of Psychological Medicine looked at high-concentration full-spectrum ashwagandha root extract. They found it significantly reduced serum cortisol levels over a 60-day period. If you take it in the morning, you’re essentially "pre-gaming" for the stress of traffic, emails, and that one coworker who always eats your yogurt.
But watch out for the empty stomach trap.
Some people swear by taking it before breakfast. They think it absorbs faster. Maybe. But for a lot of folks, ashwagandha on an empty stomach leads to a "sour" feeling or mild nausea. It’s a root, after all. It’s fibrous and potent. If you have a sensitive gut, take it with your eggs or avocado toast. The fat in your meal might actually help with the absorption of the fat-soluble compounds called withanolides.
Taking It At Night: The Sleep Connection
If your main goal is better sleep, the evening is your winner.
The name somnifera literally translates to "sleep-inducing" in Latin. It’s not a coincidence. Researchers have found that triethylene glycol, a component of the plant’s leaves, promotes non-rapid eye movement (NREM) sleep.
Taking it about 30 to 60 minutes before bed helps your nervous system shift from "fight or flight" (sympathetic) into "rest and digest" (parasympathetic). It’s great for the "tired but wired" crowd. You're exhausted, but your pulse is still racing? That's where the evening dose shines.
- Lowering the Midnight Cortisol Spike: Normally, cortisol should be lowest at night. Stress messes that up. Ashwagandha helps bring it back down so melatonin can do its job.
- Muscle Recovery: If you hit the gym hard in the evening, taking it afterward might help with recovery. A study in the Journal of the International Society of Sports Nutrition showed that participants taking the herb had significantly greater increases in muscle mass and strength.

Consistency is king.

Ashwagandha isn't a one-and-done miracle. It builds up. Most clinical trials that show real results—like the ones by Dr. K. Chandrasekhar—use a twice-daily dosing protocol. Usually, that’s 300mg in the morning and 300mg in the evening.
Splitting the dose keeps the active compounds steady in your system. It prevents the "crash" some people feel when a single high dose wears off. If you’re using a high-potency extract like KSM-66 or Sensoril, check the mg count. Taking 600mg or 1000mg all at once might be a bit much for your stomach to handle in one go. Split it. Your digestive tract will thank you.
Does It Actually Matter If You Miss Your "Window"?
Kinda, but don't freak out.
The most important factor in what time of day should you take ashwagandha is actually whether or not you'll remember to take it at all. If you’re a morning person who forgets everything after noon, take it in the morning. If you have a rock-solid nighttime skincare routine and can tuck your supplement in there, do that.

The benefits are cumulative. You aren't going to feel like a Zen monk after one pill. Most studies show that the most profound changes in anxiety and physical stamina happen after 4 to 12 weeks of daily use. It’s a marathon, not a sprint.
Real World Nuance: Who Should Be Careful?
It’s a "natural" herb, sure, but that doesn't mean it’s for everyone.
- The Thyroid Factor: Ashwagandha can increase thyroid hormone levels. If you have hyperthyroidism, you need to be extremely careful. Even if you're hypothyroid and on medication like Levothyroxine, the herb could potentially overstimulate your system. Always talk to an endocrinologist first.
- Autoimmune Issues: Because it can "boost" the immune system, people with Lupus, Rheumatoid Arthritis, or Multiple Sclerosis might find it flares up their symptoms.
- The "Anhedonia" Effect: This is a weird one that nobody talks about. A small percentage of users report feeling "numb" or emotionally flat after taking ashwagandha for a long time. They don't feel sad, but they don't feel happy either. If you start feeling like a robot, try cycling off it for a few weeks or reducing the dose.
How To Choose Your Extract
Don't just buy the cheapest bag of powder on the internet. It might be full of "fillers" or, worse, heavy metals. Look for "Full Spectrum" extracts.
KSM-66 is probably the most researched version; it uses only the roots and is standardized to a high percentage of withanolides. Sensoril is another popular one that uses both leaves and roots, making it a bit more potent and often better for sleep. If you want to be alert, KSM-66 in the morning is a solid bet. If you want to be a puddle on the couch, Sensoril at night might be the way to go.
Summary of Actionable Steps
- Identify your goal: Morning for anxiety management and focus; evening for insomnia and recovery.
- Start low: Try 300mg once a day to see how your stomach reacts before jumping to a higher dose.
- Pair with food: A little healthy fat helps absorption and prevents nausea.
- Be patient: Give it at least 30 days before deciding if it works for you.
- Cycle your use: Many herbalists recommend taking a week off every couple of months to prevent your body from building too much of a tolerance.
The real answer to what time of day should you take ashwagandha is simply "whenever you can do it consistently." If you're looking for that sweet spot, try 10:00 AM for workday stress or 9:00 PM for deep sleep. Just listen to your body—it usually knows better than a label does.
Stick to a high-quality, third-party tested brand. Monitor your mood and your energy levels in a journal for the first two weeks. If you notice you're getting sleepy at your desk, move your dose to the evening. If you're too energized to sleep, move it to the morning. Optimization is a personal experiment.
Next Steps for Implementation
- Check your current supplement: Verify if it is a root-only extract (like KSM-66) or a blend.
- Set a "Trial Week": Pick one specific time—either 30 minutes after breakfast or 30 minutes before bed—and stick to it for seven days straight.
- Audit your results: At the end of the week, note if your primary symptom (stress, poor sleep, or fatigue) has shifted even slightly. If you feel "heavy" or groggy the next morning after a night dose, reduce the amount by half.
