What is KSM-66 ashwagandha?

KSM-66 is a branded, standardised ashwagandha root extract developed by Ixoreal Biomed Inc. It is produced using a root-only, milk-based extraction process and is standardised to a minimum of 5% withanolides by HPLC. KSM-66 is the most clinically studied ashwagandha extract in the world, referenced in a large body of published human trials. This product uses genuine KSM-66 extract supplied under a trademark licence agreement with Ixoreal Biomed.

What is the KSM-66 500 mg dose used in clinical trials?

Published human trials on KSM-66 have used doses between 300 mg and 600 mg per day, most commonly 300 mg twice daily or a single 500-600 mg dose. Each capsule of this product contains 500 mg of KSM-66 extract, so one to two capsules daily aligns with the dose ranges used in the research. Take with food, as withanolides are fat-soluble.

How does KSM-66 differ from generic ashwagandha?

Generic ashwagandha is typically unbranded root (or root-and-leaf) powder or extract with no guaranteed withanolide concentration, and can vary batch to batch. KSM-66 is a single, consistently specified extract — root-only, standardised to at least 5% withanolides, and the form used in most published clinical research. If a supplement does not name its extract or withanolide percentage, it is not equivalent to KSM-66.

Does the NHS recommend ashwagandha?

No. Ashwagandha is a herbal food supplement, not a medicine. The NHS does not make specific supplement recommendations of this kind, and NICE (the National Institute for Health and Care Excellence) has not issued guidance endorsing ashwagandha for any condition. EFSA has also not yet authorised specific health claims for ashwagandha. If you are considering ashwagandha alongside prescription medication, speak to your GP or pharmacist first — this is especially important for thyroid, sedative, immunosuppressant and diabetes medications.

Is this the same KSM-66 used in published clinical studies?

Yes. KSM-66 is a single, trademark-protected extract produced only by Ixoreal Biomed. Any product displaying the KSM-66 name is required by trademark licence to source the extract from Ixoreal and meet their identity and quality specifications. Camden Medicals holds a licence agreement with Ixoreal Biomed Inc. to use the KSM-66 Ashwagandha trademark on this product.

Is Ashwagandha KSM-66 500 mg suitable for vegans?

Yes. The capsule shell is HPMC (hydroxypropyl methylcellulose, plant-derived) and the extract itself contains no animal-derived ingredients. The product is suitable for vegans and vegetarians, and is manufactured in the United Kingdom to GMP standards.
