About this ingredient
KSM-66® Ashwagandha is a branded extract of the root of Withania somnifera, one of the best-known botanicals in Ayurvedic herbal traditions.
The KSM-66 ingredient is designed as a full-spectrum root extract, meaning the extract aims to retain a broad range of naturally occurring Ashwagandha root compounds rather than focusing on a single isolated constituent. Withanolides are among the principal bioactive compounds associated with Ashwagandha.
Human research on Ashwagandha preparations has reported potential effects on perceived stress and related outcomes. For example, randomized controlled studies of standardized Ashwagandha root preparations have reported reductions in perceived stress and cortisol, although these studies used different branded extracts and therefore should not automatically be interpreted as clinical evidence specifically for KSM-66®.
For Wellmart.pk product listings, it is important to distinguish KSM-66® from generic Ashwagandha powder, generic Ashwagandha extract and root-and-leaf extracts. The exact extract specification and standardized withanolide content should be taken from the product's current certificate of analysis or official specification.
