A clinically validated, organic adaptogen that reduces cortisol, supports cognition, mood, hormonal balance, muscle recovery, and resilience to physical and mental stress.

KSM-66® Ashwagandha (Withania somnifera Root Extract)

600 mg

Each batch of KSM-66® ashwagandha extract is standardized to contain 5% withanolides, the primary bioactive constituents in the herb [1]. This specific ashwagandha root extract (KSM-66®) has been clinically evaluated in 24 human studies, a feat that no other ashwagandha extracts have matched [2]. The findings of these studies demonstrate the compelling benefits of KSM-66® for human health and longevity, especially concerning anxiety, chronic stress, sex hormone production, body weight management, and cognitive functions/mental clarity. 

Ashwagandha (Withania somnifera), also known as Indian ginseng, is arguably the most versatile adaptogenic herb known to man. Adaptogenic herbs are so-named because they help the body adapt to and overcome physical and mental stress through diverse mechanisms, such as modulating stress hormone production (e.g., lowering cortisol levels) and attenuating inflammation.

Several recent research reviews comprising preclinical and clinical trials suggest that the health benefits of ashwagandha extract include [3,4]:

  • Controlling stress hormones (e.g., cortisol) and fighting anxiety 
  • Easing inflammation and oxidative stress
  • Enhancing mood and mental performance
  • Promoting healthy metabolic, endocrine, and immune function
  • Supporting blood glucose balance and insulin sensitivity
