KSM-66: a named, full-spectrum ashwagandha root extract, chosen for a clearly defined botanical identity.
What it is
Ashwagandha is the common name for Withania somnifera, a plant used in traditional Ayurveda. Its roots contain naturally occurring compounds including withanolides.
Why extract identity matters
Root powder, root extract and root-and-leaf extracts differ in composition. KSM-66 is a named root extract, which makes the ingredient used in our formula clear.
Suitability
Avoid ashwagandha during pregnancy or breastfeeding. Ask a pharmacist before use if you take medicines or have thyroid, autoimmune or liver concerns. Rare liver injury has been reported with ashwagandha supplements.
Why we use it
We choose KSM-66, a full-spectrum extract made from ashwagandha root. Using a named extract gives our formula a defined botanical identity, rather than treating every root powder and extract as the same ingredient. Our organic ashwagandha capsules pair it with organic black pepper.

Scientific Studies
Want To Learn More?
The 2012 placebo-controlled trial studied a full-spectrum root extract at 300 mg twice daily for 60 days in 64 adults with a history of stress. Later research used different populations and protocols. We identify the extract in our formula so the research can be read precisely, without treating all ashwagandha preparations as equivalent.
