There is no proven best time to take ashwagandha or shilajit, because no study has compared morning with night dosing. Most ashwagandha trials split the daily amount into two doses, so a practical approach is to take it after breakfast and after dinner, shifting more towards the evening if it makes you drowsy or if better sleep is your main aim. Shilajit is traditionally taken in the morning with warm milk or water, and for both, taking them consistently and after food matters more than the exact hour.
Key takeaways
- No clinical study has compared taking ashwagandha in the morning with taking it at night.
- Most KSM-66 ashwagandha trials used 300 mg twice daily, and one insomnia trial allowed it to be taken with milk or water.
- Drowsiness is a known side effect of ashwagandha, so evening dosing suits people who feel sleepy after taking it.
- Taking ashwagandha and shilajit after meals may reduce stomach upset, the most common side effect.
- Keep tea and coffee away from meals and supplements; caffeine can affect the body for up to 7 hours.
Is it better to take ashwagandha in the morning or at night?
Neither is proven to be better. The right time depends on why you are taking it and how your body reacts, and many people do well splitting it between morning and evening, as most trials did.
Clinical trials of KSM-66, a standardised root extract of ashwagandha (Withania somnifera), have typically used one 300 mg capsule twice a day2. The trials did not test whether one time of day works better than another. What we do know is that drowsiness is one of ashwagandha's recognised side effects14, which gives a sensible rule of thumb.
Choose evening if:
- Ashwagandha makes you feel sleepy or heavy during the day.
- Your main aim is to unwind and support sleep quality. The sleep trials found the clearest benefits in people with insomnia3.
- You work long hours and find mornings rushed, making it easy to miss a dose.
Choose morning and evening if:
- You are using it for general stress and day-to-day energy, and it does not make you drowsy.
- Your product directions say twice daily, as many capsule formulas do.
- You want to mirror the twice-daily pattern used in most trials.
If you work night shifts or rotating shifts
Many people in IT, BPO, healthcare and manufacturing work nights or rotating shifts, where "morning" and "night" lose their usual meaning. In that case, anchor your doses to your meals and your main sleep period instead of the clock. Take one dose after the meal you eat on waking, and the other after your last main meal before sleep. If ashwagandha makes you drowsy, avoid taking it before a shift where you need to stay alert or drive. Shift work itself is a common cause of tiredness, so protecting a consistent sleep window matters far more than the timing of any supplement.
Whatever you choose, drive or operate machinery only once you know how ashwagandha affects you. For a fuller picture of what the trials found, see our guide to what the KSM-66 ashwagandha research says.
When is the best time to take shilajit?
Shilajit is traditionally taken in the morning, usually dissolved in warm milk or water, but there is no research on whether timing changes its effects. After breakfast is a practical, easy-to-remember choice.
Shilajit is a mineral-rich resin that seeps from rocks, mainly in the Himalayas, and is made up largely of humic substances, with fulvic acid considered its main active component6. In Ayurveda it is regarded as a Rasayana, a rejuvenating substance. Human research is limited: in a 2019 trial, 63 young men took 250 mg or 500 mg of purified shilajit a day for eight weeks, and the study did not examine timing at all5.
Because shilajit is often described traditionally as warming and invigorating, many people prefer it in the first half of the day. That is a reasonable personal choice rather than a rule. If you take shilajit and ashwagandha in one combined capsule, simply follow the label.
Shilajit is sold as a soft resin, a powder and in capsules. Resin is usually dissolved in a warm drink, which makes the amount harder to measure precisely; capsules are simpler because the amount per capsule is printed on the pack. Whichever form you use, keep to the directions and avoid adding extra.
Purity matters more than timing
Raw, unpurified shilajit may contain fungal toxins, heavy metals and other contaminants, and a 2012 review warned that taking it without purification may risk intoxication6. Only use purified shilajit from a licensed maker that can share batch test results.
Ashwagandha and shilajit timing guide
Use this table as a starting point and adjust to your routine and your product's directions.
| Your main goal | Suggested timing | Why | Take with |
|---|---|---|---|
| Winding down and better sleep | After dinner, 1 to 2 hours before bed | Drowsiness is a possible effect; sleep trials showed benefit in insomnia3 | Warm milk or water |
| Everyday stress resilience | After breakfast and after dinner | Mirrors the twice-daily dosing used in most trials2 | Warm milk or water |
| General energy and stamina | After breakfast and after dinner | Steady daily use matters more than the hour | Warm milk or water |
| Shilajit on its own | After breakfast | Traditional morning use; no timing research | Warm milk or water |
| Combined capsule | As per label, usually after meals | Formula-specific directions | As per label |
Should you take ashwagandha and shilajit with food or on an empty stomach?
For most people, after a meal is better. Stomach upset, loose stools and nausea are the most common side effects of ashwagandha1, and taking it with food is the simplest way to reduce them.
Some practitioners recommend taking herbs on an empty stomach for faster absorption, but there is no good evidence that this improves results, and it does raise the chance of an upset stomach. If you have a sensitive stomach, acidity or reflux, after-meal dosing is the safer choice.
Why milk is traditional
In Ayurveda, the liquid a herb is taken with is called the anupana, or vehicle. Warm milk is the classic anupana for ashwagandha because both are considered nourishing and calming, and a pinch of cardamom, nutmeg or a little ghee is sometimes added. The 2019 insomnia trial of KSM-66 allowed participants to take their capsules with either milk or water2, so either works. Warm water is a good option if you are lactose intolerant, vegan or watching calories, and unsweetened plant-based milk is fine too. Try to avoid loading the milk with sugar.
Can you add honey or ghee?
A small amount of ghee in warm milk is a traditional way to take ashwagandha, and a little honey can be stirred in once the milk has cooled slightly. Ayurveda traditionally advises against heating honey and against mixing honey and ghee in equal quantities, so if you use both, keep the amounts clearly unequal. If you are managing your weight or blood sugar, skip the honey and keep ghee to a small spoonful.
Can you take ashwagandha and shilajit at the same time?
Yes. The two are often combined, either in a single capsule or taken together with warm milk, and there is no known reason to separate them by several hours. No trial has tested the pair, though, so keep to sensible doses.
The main risk is unintentionally doubling up. Ashwagandha appears in many men's wellness formulas, stress blends and sleep products, and shilajit is common in stamina tonics. If you take a combined product, do not add separate ashwagandha or shilajit on top. For more on why the two are paired, and where safed musli fits, read our guide to the shilajit, ashwagandha and safed musli combination.
How long should you take ashwagandha before judging if it suits you?
Most trials measured results after 8 to 10 weeks of daily use, so a fair trial means taking it regularly for at least that long, although responses vary and no timeline can be promised.
A 2021 meta-analysis of five sleep trials found the benefits were larger in studies lasting at least eight weeks and at doses of 600 mg a day or more3. The 2019 insomnia trial ran for ten weeks2. On the safety side, ashwagandha appears well tolerated for up to about three months, but long-term safety is not established14.
- Take it at the same times every day; a pill organiser or phone reminder helps.
- Keep a short note of your sleep, stress and energy each week so you can judge honestly.
- If you notice no difference after a fair trial, do not increase the dose; review whether it suits you.
- If you want to continue beyond about three months, discuss it with your doctor or practitioner.
What if you miss a dose?
Simply take the next dose at its usual time. Do not double up to make up for a missed capsule, as that only raises the chance of side effects such as stomach upset or drowsiness.
Missed doses are most common when routines change, such as during travel, festivals, weddings or busy weeks at work. A few practical habits help:
- Keep your capsules next to something you use after every meal, such as your water bottle or tiffin.
- Carry a small, labelled pill case when travelling, and keep the original pack for its directions and batch number.
- If you change time zones, shift to the new meal times rather than trying to keep home hours.
- If you have missed several days, restart at the label dose rather than trying to catch up.
What should you avoid taking with ashwagandha and shilajit?
Avoid alcohol and other sedating products alongside ashwagandha, keep tea and coffee away from your doses and meals, and check for interactions with any regular medicines.
- Alcohol and sedatives. Ashwagandha can cause drowsiness and may interact with sedatives4. Avoid combining it with alcohol, sleeping tablets or other calming supplements unless your doctor agrees.
- Tea and coffee close to meals. The ICMR-National Institute of Nutrition advises avoiding tea and coffee before, during or soon after meals, as tea binds dietary iron8. Since you take these supplements after meals, a gap before your chai is sensible.
- Late caffeine. Caffeine's effects can last up to 7 hours7, which can work against an evening dose taken to support sleep. Try to have your last cup by early afternoon.
- Certain medicines. Ashwagandha may interact with medicines for thyroid, diabetes, blood pressure, seizures and immune suppression4. Speak to your doctor before starting if you take any of these.

A sample daily routine for a busy working day
Here is how ashwagandha and shilajit can fit into a typical Indian working day, built around Ayurveda's dinacharya, or daily routine.
- 6:30 to 7:00 am: Wake at a fixed time, drink a glass of warm water and take a short walk or do 10 minutes of yoga.
- Before bathing: A few minutes of oil massage if you have time; our guide to abhyanga self-massage shows how.
- 8:00 am: A proper breakfast, then your first capsule with warm milk or water.
- 1:00 to 2:00 pm: Lunch as the main meal of the day, followed by your last tea or coffee.
- 6:00 to 7:00 pm: A 20 to 30-minute walk, even if it is just around the colony.
- 8:00 to 8:30 pm: A lighter dinner, then your second capsule with warm milk.
- 10:30 pm: Screens away and lights dim, aiming for a consistent bedtime.
If your workday runs later, shift the whole routine, but keep the gaps the same: supplement after meals, caffeine well before bed, and dinner two to three hours before sleep. Our guide to habits that drain men's energy has more ideas.
Where Purely Yours Ashwa Vigour fits
Ashwa Vigour combines KSM-66 Ashwagandha, Himalayan Shilajit and Safed Musli in vegan capsules, so you do not need to time separate products. It is designed to support everyday energy, stamina and strength, and the suggested use is one capsule twice daily after meals with warm milk or water, which fits the routine above. It has not been tested in its own clinical trial. It is not a treatment for tiredness caused by anaemia, thyroid disease, diabetes, depression, sleep apnoea or any other condition, and it does not replace medical care. Super Beast Mode is a broader formula that adds Ginseng, Gokshura, Maca root, Jatiphala and Kapikacchu for strength and stamina support. Because Super Beast Mode contains Kapikacchu (a natural source of L-dopa), Ginseng and Jatiphala (nutmeg), check with your doctor before taking it if you take medicines for Parkinson’s disease, depression, blood thinning or diabetes.
When to see a doctor
- Tiredness has lasted more than two to three weeks without a clear reason, or is affecting work or driving.
- You develop yellow eyes or skin, dark urine, pale stools or itching after starting ashwagandha or shilajit.
- You notice palpitations, tremor, sweating or unexplained weight loss, which may signal a thyroid change.
- You feel excessively drowsy during the day, especially if you also take sleeping tablets or anxiety medicines.
- You take medicines for diabetes, blood pressure, thyroid or seizures and want to add any herbal product.
- You are pregnant, breastfeeding or planning surgery.
Persistent tiredness needs a proper check-up with blood tests, usually including haemoglobin, thyroid function, blood sugar, vitamin B12 and vitamin D. You can also book a free consultation with our Ayurveda team to plan a routine that suits your schedule.
The bottom line
There is no proven best hour for ashwagandha or shilajit: take them after meals, at the same times each day, and lean towards the evening if ashwagandha makes you drowsy or sleep is your main goal. Choose purified, clearly labelled products, keep caffeine and alcohol away from your doses, and check with a doctor if you have a health condition or take regular medicines. You can browse our men's wellness range to find a formula that fits your routine.
Frequently asked questions
Is it better to take ashwagandha in the morning or at night?
There is no single best time, because no study has compared morning with night dosing. Most trials split the dose into two a day. If ashwagandha makes you drowsy, or you mainly want support with sleep, take it in the evening. If it does not affect you, morning and evening doses after meals work well for most people.
When should I take shilajit?
Shilajit is traditionally taken in the morning with warm milk or water, but no research has tested whether timing matters. Taking it after breakfast is a practical choice for most people. Consistency matters more than the exact hour, and you should only use purified, tested shilajit from a licensed manufacturer.
Should ashwagandha be taken with milk or water?
Either is fine. Ayurveda traditionally pairs ashwagandha with warm milk as a nourishing vehicle, and one clinical trial allowed participants to take it with milk or water. If you are lactose intolerant, vegan or watching calories, warm water or a plant-based milk works just as well.
Can I take ashwagandha and shilajit together?
Yes, they are commonly taken together and are often combined in one Ayurvedic capsule. No trial has tested the pair, so follow your product label, take it after meals and avoid adding separate ashwagandha or shilajit products. Check with a doctor first if you are pregnant, have a medical condition or take regular medicines.
How long should I take ashwagandha before judging if it suits me?
Clinical trials usually measured results after 8 to 10 weeks of daily use, and a sleep meta-analysis found larger effects in studies lasting 8 weeks or more. Responses vary, so no timeline can be promised. Short-term use of up to about three months appears well tolerated; review with your doctor before continuing longer.
