What is KSM-66® Ashwagandha?
KSM-66® is a full-spectrum root extract that maintains the natural balance of active compounds found in the ashwagandha plant. Developed through a proprietary extraction process, it delivers the highest concentration of bioactive withanolides available in root-only extracts — while preserving safety and tolerability.
With more than 20 published clinical studies, KSM-66® has become the benchmark ashwagandha ingredient in the global supplement market. Known for its benefits in stress, cognition, and recovery, it is also set apart by its neutral flavor profile. While most ashwagandha extracts are bitter and difficult to work with, KSM-66® offers a cleaner taste, making it easier to integrate into beverages, powders, capsules, and functional foods without compromising the consumer experience.
