KSM-66 Ashwagandha is a high-concentration, full-spectrum root extract of Withania somnifera, standardized to deliver high levels of withanolides. It is widely recognized for its adaptogenic properties—helping the body resist physical and psychological stress.
In fitness and sports contexts, KSM-66 may improve strength, reduce cortisol levels, enhance recovery, and support testosterone levels in men. Clinical studies have shown improvements in VO₂ max and reductions in exercise-induced muscle damage.
It is commonly used in performance-enhancing and stress-support formulas for both athletes and individuals under physical or lifestyle stress.
