Legion Athletics KSM-66® Ashwagandha Root Extract is an adaptogenic single-ingredient supplement that delivers 600 mg per serving of KSM-66®, a patented, root-only form of ashwagandha standardized to 5% withanolides. Standardization matters: withanolide concentration in commodity ashwagandha ranges from 1% to over 35% depending on how the plants are grown and processed, so an unspecified extract may be underdosed or overdosed. KSM-66® has been tested in 24+ clinical trials and is considered the gold standard.
