Ashwagandha Capsules give you a concentrated ashwagandha root extract, standardised to withanolides, the main compounds in the root. Each capsule provides 450mg of a 10 to 1 root extract at 1.5% withanolides. You take two to three capsules a day with food, split across meals. One pot holds 90 capsules, which is a 45 day supply at two a day.
Ashwagandha is a root used in Ayurvedic practice for centuries and one of the adaptogenic herbs, the group traditionally taken during periods of demand. Root powder varies from batch to batch, so this extract concentrates the root ten times and states its withanolide content, which gives every capsule the same measured amount.
Ashwagandha Capsules are most useful for:
Each capsule provides 450mg of ashwagandha root extract at 10 to 1, standardised to 1.5% withanolides. The other ingredients are maltodextrin and the vegetable capsule shell. Withania somnifera, Indian ginseng and winter cherry are other names for it.
Take two to three capsules a day with food, split across meals. Two a day is the usual starting point, while three a day is the stronger amount. If you take it for the evening, take one capsule with breakfast and two with dinner. Allow four to eight weeks of daily use before you judge it. When you stop, taper over one to two weeks rather than stopping at once.
The capsules are suitable for vegans and vegetarians. They are free from gluten, dairy and nuts. Anyone under 16 should not take them.
The capsules are made in the UK in a GMP certified cleanroom facility accredited to ISO 9001 and ISO 14001. Every batch is traceable from raw material to finished product. Like every supplement Nutri Tailor stocks, they are practitioner grade and guaranteed additive free.
Root extract or root powder, does the withanolide percentage matter?
Root powder is the ground root as it is, so its withanolide content changes from batch to batch. A standardised extract concentrates the root and states that content, so each capsule gives a known amount. This one is a 10 to 1 extract at 1.5% withanolides, 450mg per capsule. Branded extracts standardise to other percentages at other prices, but the plant and the compounds are the same.
How much ashwagandha should I take a day?
Take two to three capsules a day, which gives you 900mg to 1,350mg of the extract. Start at two and move to three if you want the stronger amount.
When is the best time to take ashwagandha?
With food, split across your meals. For a calmer evening take the larger share with dinner, which is where its calming side sits.
Can I take it with other supplements?
Yes. It is often taken alongside Magnesium Bisglycinate (Glycinate) Capsules in the evening, which contribute to normal psychological function. Start with one adaptogen before adding another, so you know how you respond to each.
How long does ashwagandha take to work?
Most people give it four to eight weeks of daily use before judging it. It builds its effect over weeks rather than hours.
Does ashwagandha have side effects?
Taken with food it is well tolerated. Taper over one to two weeks when you stop. If you take prescribed tablets, are pregnant or breastfeeding, speak to your GP or pharmacist first.

Withania somnifera, one of the most widely researched adaptogenic herbs, used in traditional practice for centuries and now studied in modern clinical trials for the body's response to stress.
A plant that helps the body manage stress by supporting a balanced response rather than amplifying or sedating it. Ashwagandha is among the best studied.
45 days at the suggested daily dose of the concentrated root extract.
Energising adaptogens like rhodiola work best in the morning. Calming ones like ashwagandha can be taken evening.
Yes, adaptogens often work synergistically. Start with one, then add others once you know how you respond.
Root powder is the ground root as it is, so the amount of withanolides, the compounds the research measures, varies from batch to batch. A standardised extract concentrates the root and states its withanolide content, so each capsule gives a known amount; this one is a 10 to 1 root extract at 1.5 percent withanolides, 450 mg per capsule. Branded extracts standardise to different percentages and prices, but the plant and the compounds are the same. Choose the extract if you want a measured dose; powder suits people who prefer the whole root in a drink.
Tablets need binders, fillers and a coating to hold their shape. A capsule is a cellulose shell around the powder, so it carries no binders and breaks down quickly once swallowed.
