Why KSM-66®?
Not all Ashwagandha extracts are the same. Many generic extracts are manufactured using combinations of roots and leaves, which can provide a different phytochemical profile from traditional root-based Ashwagandha preparations.
KSM-66® is different.
It is produced exclusively from the roots of the Ashwagandha plant, without using leaves. This root-only approach follows the traditional use of Ashwagandha while providing a modern, standardized extract with 5.22% withanolides.
KSM-66® has also been extensively studied in human clinical research, making it one of the most recognized and scientifically established Ashwagandha ingredients available to supplement manufacturers.
For premium formulations where ingredient quality, consumer recognition, and scientific substantiation matter, KSM-66® provides a clear step up from generic Ashwagandha extracts.

Frequently Asked Questions
What is KSM-66® Ashwagandha?
KSM-66® is a branded, standardized Ashwagandha extract produced from Withania somnifera. It is particularly well known for being manufactured exclusively from the roots of the Ashwagandha plant and for its extensive body of clinical research. It has become one of the most recognized premium Ashwagandha ingredients used by supplement brands worldwide.
Is KSM-66® made only from Ashwagandha root?
Yes. KSM-66® is a 100% root-only Ashwagandha extract. No Ashwagandha leaves are used in the extraction process. This is an important distinction because some generic Ashwagandha extracts use both roots and leaves to achieve their desired withanolide concentration. KSM-66® maintains a root-only approach consistent with the traditional use of Ashwagandha.
Why does root-only Ashwagandha matter?
The root is the part of the Ashwagandha plant traditionally associated with its use in Ayurveda. Roots and leaves have different phytochemical profiles, so simply comparing the total percentage of withanolides does not tell the complete story about an Ashwagandha extract. KSM-66® combines a root-only extraction philosophy with modern standardization, making it particularly attractive for premium formulations focused on authenticity and ingredient transparency.
What does 5.22% withanolides mean?
Our KSM-66® raw material is standardized to 5.22% withanolides, the naturally occurring compounds commonly used as key markers of Ashwagandha extract potency. This means manufacturers receive a clearly defined and consistent active compound concentration, making accurate formulation and batch-to-batch consistency easier.
Is KSM-66® the most researched Ashwagandha extract?
KSM-66® is widely recognized as one of the most extensively researched branded Ashwagandha extracts available, with a substantial body of human clinical research. Its scientific background is one of the key reasons it is frequently selected by premium supplement brands instead of generic Ashwagandha extracts.
What is KSM-66® Ashwagandha commonly used for?
KSM-66® is widely used in formulations targeting stress management, relaxation, sleep, cognitive performance, physical performance, recovery, vitality, and general wellbeing. Its versatility makes it suitable for standalone Ashwagandha products as well as complex adaptogen, nootropic, sports nutrition, and wellness formulas.
What is the difference between KSM-66® and generic Ashwagandha extract?
Generic Ashwagandha extracts can vary significantly in plant part, extraction method, standardization, and research background. KSM-66® offers several important differentiators: a recognizable branded ingredient, 100% Ashwagandha root - no leaves, standardized 5.22% withanolide content, extensive clinical research, consistent manufacturing and quality specifications. These characteristics make KSM-66® particularly suitable for premium products where ingredient provenance and scientific substantiation are important.
What packaging sizes are available?
BULKvitamins supplies KSM-66® Ashwagandha Extract in flexible bulk quantities ranging from 100 g to 25 kg. Smaller quantities are ideal for formulation development, testing, and smaller production runs, while larger quantities are suitable for commercial-scale supplement manufacturing.
Do you provide a Certificate of Analysis (COA)?
Yes. Batch-specific quality documentation is available, allowing professional buyers and manufacturers to verify relevant specifications, including the standardized withanolide content.
Is KSM-66® suitable for private label and contract manufacturing?
Absolutely. KSM-66® is particularly well suited to premium private label supplements where the branded ingredient itself can become an important part of the product's positioning. It can be incorporated into standalone Ashwagandha supplements, adaptogenic complexes, nootropic formulas, sports nutrition products, sleep-support blends, and other wellness formulations. With quantities available from 100 g to 25 kg, BULKvitamins can support everything from initial product development to larger commercial production.
