Best Ashwagandha Supplements in Australia

Ashwagandha labels vary more than most. Some use a branded root extract such as KSM-66, others a root-and-leaf extract such as Sensoril, and the amount per capsule on our shelves ranges from 125 mg to 600 mg. This page ranks the ashwagandha supplements our customers buy most at Supps247, checks each label for extract type, amount per serve and withanolide content, and sets out who should avoid ashwagandha or check with a doctor first. Updated October 2026.

Our top picks at a glance

Figures are per label serve, from the label panels on each product listing.

1. Beast Labs Nutrition Ashwagandha 600mg: best overall

Beast Labs Nutrition Ashwagandha is our best-selling ashwagandha by a wide margin. One capsule gives 600 mg of extract standardised to 5% withanolides, and the only other ingredient is the vegetarian capsule. The NIH Office of Dietary Supplements notes that in several stress studies, benefits appeared greater at 500 to 600 mg a day, so one capsule sits at that level without any counting.

• 600 mg ashwagandha extract (5% withanolides) per capsule
• 1 capsule per serve, 60 serves per bottle
• Ingredients: ashwagandha extract and an HPMC vegetarian capsule shell, nothing else
• Made in Australia from imported ingredients; labelled as a formulated supplementary sports food

Worth knowing: The label does not name a branded extract or say whether it uses root only or root and leaf, so it is harder to match to specific studies than KSM-66. The safety notes further down this page apply to every pick.

2. ALLMAX Essentials Ashwagandha KSM-66: best KSM-66 split dose

If you want KSM-66, the branded root-only extract used in several of the trials the NIH summarises, Allmax is our best seller. A serve is two capsules, one taken in the morning and one in the evening, for a total of 600 mg of KSM-66 standardised to 5% withanolides. Splitting the dose suits people who prefer a smaller amount at a time.

• 600 mg KSM-66 ashwagandha root extract per 2-capsule serve, standardised to 5% withanolides
• Label directions: 1 capsule twice a day
• 60 veggie capsules, 30 serves
• Other ingredients: hypromellose capsule, microcrystalline cellulose, magnesium stearate, silicon dioxide

Worth knowing: With 30 serves per bottle it is the most expensive pick per serve; NOW's KSM-66 gives the same 600 mg in one capsule. It is made in a facility that also handles milk, soy, egg, peanut, tree nuts, sesame, fish, crustacean and shellfish.

3. Ashwagandha by Primabolics: best for starting low

Primabolics' ashwagandha is Australian owned and manufactured, and at 150 mg of extract per capsule it is a gentle starting point for people who want to see how they respond. The extract is standardised to 5% withanolides, and the 120-capsule bottle costs less per capsule than any other pick on this page.

• 150 mg ashwagandha extract (5% withanolides) per capsule
• 1 capsule per serve, 120 serves per bottle
• Vegetarian HPMC capsule, with no other ingredients listed
• Australian owned and manufactured, according to the label

Worth knowing: One capsule is well below the 500 to 600 mg a day at which the NIH says benefits appeared greater in several studies. Follow the label directions, and ask your pharmacist before taking more than one capsule a day.

4. KSM-66 Ashwagandha by NOW Foods: best one-a-day KSM-66

NOW puts 600 mg of organic KSM-66 root extract into a single vegan capsule, so one capsule a day matches Allmax's two-capsule serve. With 90 capsules per bottle, it also costs much less per 600 mg serve than Allmax, which makes it our pick for KSM-66 value.

• 600 mg organic KSM-66 ashwagandha root extract per capsule
• Suggested use: 1 capsule daily
• 90 veg capsules; labelled vegetarian, vegan and non-GMO
• Not made with yeast, wheat, gluten, soy, milk, egg, fish, shellfish, tree nut or sesame ingredients (made in a GMP facility that processes them)

Worth knowing: NOW's label says it is not recommended in pregnancy or breastfeeding, asks people taking thyroid medication or with thyroid, liver or gastrointestinal conditions to see a doctor first, and notes it may cause digestive upset. Stock is limited, so check the product page.

5. NOW Foods Ashwagandha 450 mg: best budget extract

This is a lower-cost, non-branded option: 450 mg of ashwagandha root and leaf extract per vegan capsule, standardised to at least 2.5% total withanolides. It suits people who want a standardised extract from a large, established brand without paying for a branded one.

• 450 mg ashwagandha root and leaf extract per capsule
• At least 2.5% total withanolides, which the label lists as 11 mg per capsule
• 90 veg capsules, 1 capsule per serve
• Other ingredients: hypromellose capsule, stearic acid and rice flour

Worth knowing: Withanolides per capsule are about a third of a 600 mg, 5% extract (11 mg compared with about 30 mg). The NIH notes that ashwagandha root and leaf differ chemically and that most commercial supplements use root extracts.

6. Life Extension Optimized Ashwagandha: best Sensoril

Sensoril is a branded ashwagandha extract made from root and leaf, and Life Extension uses 125 mg of it per capsule. It is standardised differently from KSM-66, to 32% oligosaccharides and 10% withanolide glycoside conjugates, so it suits people who specifically want Sensoril.

• 125 mg Sensoril ashwagandha root and leaf extract per capsule
• Standardised to 32% oligosaccharides and 10% withanolide glycoside conjugates
• 60 vegetarian capsules, 1 capsule per serve
• Labelled gluten free and non-GMO

Worth knowing: Sensoril and KSM-66 are different extracts, so their milligram figures cannot be compared directly. It costs more per milligram of extract than any other pick here.

How we chose

We ranked ashwagandha products by units sold at Supps247 over the last six months and kept single-ingredient ashwagandha supplements that are live online and in stock. Products that tied on units were ordered to cover a different extract or dose. We left out multi-ingredient blends, products we could not match to a current brand label, and products that are sold out or not available online. Label facts were checked against the label panels on each listing in October 2026. Value tiers come from price per label serve at the time of writing: $ is lower than most picks here, $$ is in the middle and $$$ is premium. Because doses range from 125 to 600 mg, compare the milligrams as well as the tier. Brands do not pay for placement.

How to choose an ashwagandha supplement

Check the extract and the plant part. KSM-66 is a root extract, while Sensoril and Shoden use root and leaf. The NIH Office of Dietary Supplements says preparations and doses vary so much that it is difficult to identify specific extracts or recommended amounts. A label that names the extract, the plant part and the withanolide percentage is easier to compare than one that just says ashwagandha.

Know what the research looked at. A 2021 review summarised by the NIH covered seven trials in 491 adults taking 240 to 1,250 mg a day for 6 to 8 weeks, all run in India, and found reduced stress and anxiety compared with placebo; several studies suggested larger benefits at 500 to 600 mg a day. Sleep evidence is limited to a small number of studies. Results come from different extracts, so they do not automatically apply to every product.

Give it weeks, not days, and keep it short term. Most trials ran 6 to 12 weeks. The NIH says ashwagandha appears to be well tolerated for up to about three months, but its long-term safety is not known.

Safety notes

Liver. The TGA says there may be a very rare risk of liver injury from Withania somnifera. Up to February 2024 it had received 12 Australian reports of liver problems, seven with enough information to suggest possible liver injury, and four cases required hospital care. In a later update it reported four more cases, all of which resolved after the product was stopped. Stop taking ashwagandha and see a doctor if you notice yellowing of the skin or eyes, dark urine, nausea, vomiting, unusual tiredness, stomach pain or loss of appetite. People who have or have had liver problems should avoid it.

Thyroid. The NIH notes ashwagandha might affect thyroid function, with small studies showing changes in thyroid hormone levels and three case reports of an overactive thyroid that settled after stopping. If you have a thyroid condition or take thyroid medication, check with your doctor first.

Pregnancy and breastfeeding. The NIH says some experts advise against ashwagandha in pregnancy, Denmark has banned it, and France's food safety agency recommends against it in pregnancy and breastfeeding. Food first, and talk to your GP or midwife before taking any herbal supplement.

Medicines and other conditions. The NIH says ashwagandha might interact with medicines for diabetes and blood pressure, immunosuppressants and sedatives, as well as thyroid hormone. The NIH also says it might raise testosterone and might not be safe for men with hormone-sensitive prostate cancer. Reported side effects are usually mild, such as stomach upset, loose stools, nausea and drowsiness. Ask your pharmacist if you take any regular medication. Several labels on this page say adults only, so teenagers should talk to a GP first.

Tested athletes. None of our picks shows HASTA or Informed Sport certification; see our guide to supplements for drug-tested athletes. For a general overview, read our ashwagandha explainer, or compare every option in our ashwagandha range.

FAQs

What is the best ashwagandha in Australia?

It depends on the extract and dose you want. On this page, Beast Labs Nutrition Ashwagandha ranks first because it is our best seller and gives 600 mg of a 5% withanolide extract in one capsule. Choose NOW KSM-66 or Allmax KSM-66 if you want the branded KSM-66 root extract, Primabolics if you want to start with a lower dose, or Life Extension if you want Sensoril.

Which is the best KSM-66 ashwagandha?

We stock two KSM-66 products that suit different habits. NOW Foods puts 600 mg of organic KSM-66 in one capsule, with 90 capsules per bottle, so it is the better value. Allmax splits the same 600 mg across two capsules taken morning and evening, with 30 serves per bottle. Both are root-only extracts standardised to 5% withanolides.

How much ashwagandha should I take?

Follow the label for your product, because extracts differ. The trials summarised by the NIH used 240 to 1,250 mg a day of various extracts, and several suggested larger benefits at 500 to 600 mg a day. Most of our picks give 450 to 600 mg per serve, while Primabolics gives 150 mg and the Sensoril capsule 125 mg. Long-term safety beyond about three months is not known.

Is ashwagandha bad for your liver?

For most people it appears well tolerated, but the TGA says there may be a very rare risk of liver injury, which can be severe. Stop taking it and see a doctor if you notice yellowing of the skin or eyes, dark urine, nausea, stomach pain or unusual tiredness. The TGA advises that anyone who has or has had liver problems should avoid ashwagandha products.

Can I take ashwagandha with a thyroid condition?

Check with your doctor first. The NIH notes ashwagandha might affect thyroid function: small studies found changes in thyroid hormone levels, and there are case reports of an overactive thyroid that settled once people stopped taking it. It might also interact with thyroid medication, and NOW's label specifically asks people taking thyroid medication to consult a physician.

Can I take ashwagandha while pregnant or breastfeeding?

It is best avoided unless your doctor says otherwise. The NIH reports that some experts advise against ashwagandha in pregnancy, Denmark has banned it, and France's food safety agency recommends against it in pregnancy and breastfeeding. Several labels on this page also say it is not recommended. Talk to your GP or midwife before taking any herbal supplement.
