Ashwagandha capsules, tablets or powder: what's the difference?

Short answer: Ashwagandha capsules, tablets, powder and gummies all contain the same plant, Withania somnifera, but not in the same form. The difference comes down to three things: ground root or extract, how many mg you get per day, and what else is in it, such as binders in tablets or sugar in gummies. Capsules are the easiest to dose, powder is the most flexible, and with tablets and gummies it pays to read the label closely.

At GOYU we sell ashwagandha in three forms: KSM-66 capsules, capsules with ground root and powder. We don't sell tablets or gummies, but you will find them everywhere, including at drugstores. Below we put all the forms side by side, using the figures from our own labels. What ashwagandha is and what has been studied is covered in ashwagandha: effects and KSM-66.

What is the difference between ashwagandha capsules, tablets and powder?

The biggest difference is not the form but what is inside: ground root or an extract, and how much per day. After that come convenience, taste and additives.

Ground root or extract: what is in your capsule?

First check whether it contains ground root or an extract. Ground root is the dried root, finely milled. An extract is concentrated: the plant compounds are drawn out of the root. With a standardised extract, the amount of withanolides is fixed. Withanolides are a group of plant compounds found in ashwagandha.

This is what it looks like for us, according to our labels:

• Ashwagandha KSM-66 Capsules: 500 mg organic root extract per capsule, of which 25 mg withanolides (5%).
• Ashwagandha Capsules 500 mg: 500 mg organic ground root per capsule. The label does not state a withanolide content.
• Ashwagandha powder: organic ground root, a single ingredient.

The sleep studies summarised by Cheah and colleagues used extracts of 120 to 600 mg a day (Cheah et al., 2021). So you cannot transfer those results one to one to capsules with ground root or to powder. What KSM-66 is exactly and what to look for when buying is covered in buying ashwagandha: what to look for.

No health claims for ashwagandha have been definitively authorised in the EU yet. All three of our products carry these claims, which are pending assessment by the European Commission:

• Ashwagandha helps the body cope with stress*
• Ashwagandha helps maintain mental balance*
• Ashwagandha supports falling asleep*
• Ashwagandha helps maintain energy levels*
• Ashwagandha contributes to relaxation*

*Health claim pending approval by the European Commission.

How many mg of ashwagandha are in a daily dose?

Count per day, not per capsule. This is what our labels say:

So a capsule with ground root holds roughly half a scoop of powder. You cannot compare a KSM-66 capsule with that: 500 mg of extract is not the same as 500 mg of root. Take all three during or just after a meal and do not exceed the daily dose on the label.

If you see "ashwagandha 500 mg" on a pack, check whether it refers to root or extract and how many you take per day. How long studies ran before researchers measured a difference is explained in how long does ashwagandha take to work?

Ashwagandha capsules: who are they for?

Capsules are handy if you don't want to taste anything and want a fixed amount. You swallow them with water and there is nothing to measure. Check the capsule shell: HPMC is plant-based, gelatine is not. Our capsules have an HPMC shell and contain no fillers, just ashwagandha and the capsule shell.

If you are choosing between our two capsules, the main question is: do you want an extract with a fixed withanolide content (KSM-66), or the ground root, the part of the plant that is traditionally used?

Ashwagandha tablets: how are they different from capsules?

A tablet is pressed powder or extract. To press the powder into a firm tablet, manufacturers often use additives, such as a binder or a lubricant that stops the powder sticking to the press. Some tablets also get a coating. These are permitted ingredients, but they will appear in the ingredients list. It can be done without them: our chlorella tablets, for example, contain nothing but chlorella.

For the rest, check the same things as with capsules: root or extract, how many mg per tablet and how many tablets a day.

Ashwagandha gummies: what should you look out for?

Gummies are sweets with ashwagandha in them, and you see them more and more, including at drugstores. Check three things:

1. How much ashwagandha per gummy. Check whether it is root or extract, how many mg are in one gummy and how many gummies make up the daily dose.
2. What else is in it. Besides ashwagandha, a gummy contains sugar or sweetener, a gelling agent such as pectin or gelatine, and usually flavouring. Gelatine is not vegan.
3. Out of reach of children. Gummies look like sweets, and the French authorities advise against ashwagandha for anyone under 18. So store them where children cannot get to them.

The advantage of gummies: you don't have to swallow anything. Stick to the daily dose on the label with gummies too, however tasty they are.

Ashwagandha powder: who is it for?

Powder is the most flexible form. You measure it yourself and stir it into warm (plant-based) milk, a smoothie or yoghurt. In India, ashwagandha is often taken in warm milk with spices. The taste is earthy and slightly bitter; if you would rather not taste that, capsules are easier.

Our powder is a single ingredient: organic ground root, with 37.4 g of fibre per 100 g according to the label. The powder and the capsules with ground root also carry this nutrition claim: Ashwagandha is naturally high in fibre**. How to use the powder is explained in how to use ashwagandha powder.

**Authorised nutrition claim (Regulation (EC) No 1924/2006).

Which form suits you?

• You don't want to taste or measure anything: capsules.
• You want a fixed withanolide content: a standardised extract, such as KSM-66.
• You want the ground root in warm milk or a smoothie: powder.
• You would rather not swallow anything: powder, or gummies if you keep an eye on sugar and the daily dose.
• You choose tablets: read the ingredients list for additives and check whether it is root or extract.

If you switch to a different form, start again from the daily dose on the new label. Don't add products together: use one ashwagandha product at a time.

Who should avoid ashwagandha, whatever the form?

The form does not change the warnings. For food supplements with ashwagandha, the French government requires these five warnings (Compl'Alim):

• Not recommended for pregnant or breastfeeding women.
• Not recommended for people under 18 years of age.
• Not recommended for people with endocrine disorders (particularly thyroid disorders and hyperandrogenism).
• Not recommended for people with liver or heart disorders.
• Not recommended when driving vehicles or operating machinery and/or in combination with substances that depress the central nervous system.

Our product pages also state that you should not use ashwagandha if you have or have had a liver condition. In 2023 the Netherlands Pharmacovigilance Centre Lareb received four reports of liver injury with products containing ashwagandha (Lareb, 2023). The Dutch RIVM advises, as a precaution, against using herbal preparations with ashwagandha, especially during pregnancy (RIVM, 2024), and the German BfR advises especially children, pregnant and breastfeeding women and people with current or previous liver disorders not to take food supplements with ashwagandha, and advises everyone else to be cautious (BfR, 2024). In the EU, ashwagandha in food supplements is not a novel food (Novel Food Catalogue). If you take medication, check with your doctor or pharmacist first.

Summary in 3 points

• The difference between capsules, tablets, powder and gummies is mainly what is inside: ground root or extract, how many mg per day and which additives.
• At GOYU: KSM-66 capsules with 500 mg extract (1 a day), capsules with 500 mg ground root (1 capsule once or twice a day) and powder (1 scoop of about 1 g a day).
• The warnings apply to every form: not recommended during pregnancy and breastfeeding, under 18, with endocrine, liver or heart disorders, or when driving or combined with substances that depress the nervous system.

Frequently asked questions

Which is better: ashwagandha capsules or powder?

Neither is better. Capsules are easier to dose and you don't taste anything; powder can be mixed into food and drinks. What matters more is whether it is ground root or extract and how much you get per day.

How many ashwagandha capsules should you take a day?

That depends on the product, so follow the label. Of our KSM-66 capsules you take 1 capsule a day, of our capsules with ground root 1 capsule once or twice a day, during or just after a meal.

Is 500 mg of ashwagandha extract the same as 500 mg of root?

No. An extract is concentrated. 500 mg of KSM-66 extract contains 25 mg of withanolides; with 500 mg of ground root that content is not fixed. So only compare products of the same type.

Are ashwagandha gummies as good as capsules?

You can't say that in general. It depends on how much ashwagandha each gummy contains and whether it is root or extract. Gummies also contain sugar or sweetener and a gelling agent; capsules don't.

Are your ashwagandha capsules vegan?

Yes. The capsule shell is made of HPMC, a plant-based material, and the powder consists only of ground root.
