About this supplement
KSM-66 Ashwagandha is a proprietary, full-spectrum root extract of Withania somnifera, standardized to contain a minimum of 5% withanolide glycosides. It is produced using a unique, solvent-free, aqueous extraction process that preserves the full profile of bioactive compounds from the root, including withanolides, alkaloids, and sitoindosides. KSM-66 is specifically noted for its high concentration of root-only constituents, avoiding leaf material, and is clinically researched for its adaptogenic properties, supporting stress response, cognitive function, and physical performance.

How it’s made
Produced via a proprietary, green chemistry process using only water and milk (as a solvent for certain bioactive components), without using alcohol or synthetic solvents. The process involves extracting solely from the roots of Withania somnifera, followed by concentration and drying to yield a full-spectrum extract standardized for withanolide glycoside content.
