Comparison
Best ashwagandha in the UK for women
There is no authorised EFSA health claim for ashwagandha, so the best product is not about a promised effect on stress or sleep but about a clearly stated standardised extract, the amount per serving and a transparent UK label. Below we compare named UK brands on extract, format and who each suits. Ashwagandha is not suitable in pregnancy or breastfeeding or for people with liver problems, and can interact with medication, so speak to your GP or pharmacist first.

The shortlist

Ashwagandha
Her Vitals' own ashwagandha is a capsule of organic root (Withania somnifera) with organic black pepper, not a standardised extract such as KSM-66 or Sensoril, and the label does not state a milligram strength for the root or a standardisation percentage. As above, there is no authorised EFSA health claim for ashwagandha in any form. It sits alongside the brands compared here as one option, not the pick, and is not directly comparable to extract-based products on trial-relevant terms. Do not take it if you are pregnant or breastfeeding, and check with your pharmacist or doctor first if you have a liver, thyroid or autoimmune condition or take any regular medicines.

How we compared
We shortlist real, named UK brands in each category by desk research: product form, typical dose against NHS and EFSA reference intakes (our dose and evidence constants are dated on the research index), who each product suits, and value for money. We have not hands-on tested these products and don't claim to. No brand pays for inclusion or placement, and we don't rank by commission. Some links may earn us a commission, and that is disclosed where the link appears. Our own products are labelled wherever they appear.
Frequently asked questions
What is the best ashwagandha in the UK?
There is no single best, and importantly there is no authorised EFSA health claim for ashwagandha, so any product promising results for stress, sleep or mood is going beyond what UK rules allow. A sensible choice comes down to a clearly stated standardised extract, the amount per serving and a transparent UK label. We compare named products below.
How did you choose these?
We shortlisted real UK ashwagandha brands, then compared them on the extract used, format and who each suits, with a clear note that no health claim is authorised. How we handle commission and our own products is set out in our methodology below.
What is KSM-66 ashwagandha?
KSM-66 is a branded, standardised root extract used by several supplement makers. Standardisation means the extract strength is stated, which makes it easier to compare like with like. It does not change the fact that no EFSA health claim is authorised for ashwagandha.
Who should not take ashwagandha?
Do not take ashwagandha if you are pregnant or breastfeeding: its safety has not been established. If you are trying to conceive or planning a pregnancy, ask a healthcare professional before using it. Ashwagandha supplements have been linked to rare cases of liver injury, so avoid it if you have liver disease or a history of liver problems unless a specialist advises it. Stop taking it and get urgent medical advice if you develop yellowing of the skin or eyes, dark urine, persistent nausea, unusual tiredness, itching or abdominal pain. Avoid it if you have a thyroid condition or an autoimmune condition such as rheumatoid arthritis, lupus or multiple sclerosis, unless your healthcare professional has said it is appropriate. It can interact with thyroid medicines such as levothyroxine, medicines for diabetes or high blood pressure, sedatives and some sleeping tablets, anticonvulsants and immunosuppressants. Tell your pharmacist or doctor about all the medicines, herbal remedies and supplements you take before starting it.
