About this supplement
Ashwagandha root extract is a standardized botanical preparation derived from the roots of Withania somnifera, a plant in the Solanaceae family. It is specifically standardized to contain a defined percentage of withanolides, a group of steroidal lactones considered the primary bioactive constituents responsible for its adaptogenic properties. This extract is widely used in traditional Ayurvedic medicine and modern dietary supplements for its purported ability to help the body resist physical, chemical, and biological stressors, support cognitive function, and promote overall vitality.

Physical properties
Typically a fine, brown to tan-colored powder. The extract is often soluble in water and ethanol, depending on the extraction process and carrier agents used. Has a characteristic earthy, bitter odor.
How it’s made
Produced by harvesting the roots of Withania somnifera, typically after 1-2 years of growth. The roots are cleaned, dried, and milled. The bioactive compounds are then extracted using solvents like water, ethanol, or a water-ethanol mixture. The liquid extract is concentrated and often spray-dried to produce a powder. The final product is standardized to a specific percentage of withanolides (e.g., 2.5% or 5%) through analytical testing and blending.
