Does Ashwagandha Make You Sleepy? What It Does to Sleep, and When to Take It
Share
Ashwagandha doesn't usually make you sleepy the way a sleeping pill does. It isn't a sedative. A small share of people feel drowsy when they start, and in trials people slept better after several weeks of daily use, mostly because it helps the body handle stress. If it makes you drowsy, take it in the evening. If it doesn't, the time of day is up to you.
The name doesn't help. Ashwagandha's botanical name is Withania somnifera, and "somnifera" is Latin for sleep-bringing, so people expect it to knock them out. Here is what it actually does to sleep, what the research found, and how to time it.
Sleepy and sleeping better aren't the same thing
These two get mixed up, so it helps to separate them.
- Feeling drowsy is a short-term effect some people notice within hours of a dose. In a 2020 review of the human studies, drowsiness was one of the mild side effects reported by more than 5 percent of people, along with stomach discomfort and loose stools. Most people don't feel it at all
- Sleeping better is the effect the trials measured, and it builds over weeks. People fell asleep faster and rated their sleep higher, but woke up alert rather than groggy
So if you take ashwagandha in the morning and feel fine, nothing is wrong. And if you take it and feel a little heavy in the afternoon, that's a timing issue, not a reason to stop.
What the research shows about ashwagandha and sleep
In a six-week trial published in Sleep Medicine, 150 healthy adults who woke up feeling unrefreshed took a standardized ashwagandha extract once a day or a placebo. Self-reported sleep quality improved by 72 percent in the ashwagandha group, against 29 percent on placebo. Sleep trackers also showed they fell asleep faster, slept longer and spent less time awake during the night. No treatment-related side effects were reported.
A 2021 review in PLoS One pooled five randomized trials with 400 people and found a small but real improvement in overall sleep. The effect was strongest in people who already had trouble sleeping and in trials that ran eight weeks or longer. People also reported feeling more alert on waking, and no serious side effects turned up.
And in an eight-week trial in stressed adults, the ashwagandha groups reported lower stress and better sleep quality than the placebo group.
Why ashwagandha helps sleep without knocking you out
Most of the sleep benefit seems to come through stress. In a 60-day trial in adults under chronic stress, ashwagandha lowered both stress scores and blood levels of cortisol, the main stress hormone. A mind that isn't racing at 11pm falls asleep more easily, and that shows up as better sleep without any sedation.
That's also why it takes weeks. It works on your baseline, not on tonight.
When to take ashwagandha: morning or night?
- If it makes you drowsy: take it in the evening, with dinner. That turns the side effect into a help
- If it doesn't: take it whenever you'll remember, morning or evening. Consistency matters more than the clock
- Either way: take it with a meal, at the same time every day, and judge it after a few weeks, not a few days
If your ashwagandha comes with L-theanine, like ours, timing is even more flexible. L-theanine is associated with feeling calm but alert, and in a four-week trial 200 mg a day improved sleep quality scores without being a sedative, so taking ashwagandha with L-theanine doesn't tie you to an evening dose.
Ashwagandha, melatonin and magnesium: which does what
| Ashwagandha | Melatonin | Magnesium | |
|---|---|---|---|
| What it is | An adaptogenic root | The body's own sleep-timing hormone | A mineral |
| How it helps sleep | Lowers everyday stress over time | Signals that it's night | Supports normal muscle and nerve function |
| When you notice it | After weeks | The same night | Varies |
| Makes you sleepy? | Some people, mildly | Yes, that's its job | Not directly |
They do different jobs, so people often combine them. Magnesium isn't a sedative, so if a magnesium supplement makes you sleepy, the cause is usually something else on the label. Melatonin is the one built for sleep, and even then 10 mg of melatonin is more than most people need to start with. The natural sleep aids that work best are the ones matched to why you're actually awake.
What not to mix with ashwagandha at night
Because ashwagandha can add to drowsiness in some people, be careful about stacking it with other things that do the same. Talk to your doctor first if you take sedatives, sleep medication or benzodiazepines, and go easy on alcohol in the same evening.
According to the National Center for Complementary and Integrative Health, ashwagandha should be avoided during pregnancy and breastfeeding, and you should check with your doctor first if you take thyroid, immune-system or anti-seizure medication, or have a liver, thyroid or autoimmune condition. Rare cases of liver injury have been reported with ashwagandha supplements, so stop and see a doctor if you notice yellowing skin or eyes or dark urine.
Our ashwagandha gummies, day or night
Our Ashwagandha Gummies pair 225 mg of ashwagandha with 200 mg of L-theanine in a single gummy, taken once a day with a meal. Most people take them in the morning for a steadier day. If you find they relax you, take yours with dinner instead. They're made by hand in small batches in Holmes County, Ohio.
Each gummy holds a full daily serving, so the right number of ashwagandha gummies for ours is one a day, with a meal. For the end of the day itself, our rest and wind-down range is made for exactly that.
Frequently asked questions
Does ashwagandha make you sleepy during the day?
Most people don't feel sleepy. A small share notice mild drowsiness, especially in the first week or two. If that's you, take it in the evening instead.
Does ashwagandha help you sleep?
In trials, yes, over time. People who took it daily for six to eight weeks fell asleep faster and rated their sleep higher than people on a placebo, and they woke up feeling alert.
Can I take ashwagandha at night?
Yes. Taking it with dinner is a good choice if it relaxes you. Just keep the same time every day, and check with your doctor first if you take sleep medication or sedatives.
How long does ashwagandha take to help with sleep?
The trials measured sleep after six to eight weeks of daily use, and the effect was stronger in the longer trials. Give it at least a few weeks before you judge it.
Will ashwagandha make me groggy in the morning?
It isn't known for that. In the 2021 review, people reported feeling more alert on waking. If you feel groggy, move your dose earlier in the evening or to the morning.
Can I take ashwagandha and melatonin together?
Many people do, since they work differently. Start one at a time so you know how each affects you, and ask your doctor first if you take any sleep medication.
