Core Med Science Ashwagandha KSM-66 600mg delivers the exact dose and extract form used in gold-standard human clinical trials. KSM-66 is a full-spectrum, root-only extract standardized to 5% withanolides, produced through a proprietary green chemistry process that preserves the complete active compound profile without alcohol solvents or leaf material. Delivered in a clean vegan capsule with no unnecessary fillers.

At 600 mg per serving, this is the research-validated dose shown to meaningfully support cortisol regulation, sleep quality, cognitive performance, and physical recovery. Whether tracking HRV, optimizing sleep scores, or managing the demands of a high-output lifestyle, the science behind this formula is built to support how the body responds to stress at every level.*

Benefits

Stress and Cortisol Regulation

KSM-66 works by modulating the hypothalamic-pituitary-adrenal (HPA) axis, the system that governs the body’s stress response. Multiple randomized, double-blind, placebo-controlled trials demonstrate significant reductions in perceived stress and serum cortisol levels, supporting a calmer, more resilient baseline without sedation or stimulants.*

Sleep Quality and Recovery

Clinical research shows KSM-66 improves sleep onset, sleep quality scores, and daytime energy levels. For those who track recovery metrics, consistent use over 4 to 8 weeks is associated with measurable improvements in rest and reduced fatigue.*

Cognitive Performance and Mental Clarity

The withanolide compounds in KSM-66 support GABAergic and serotonergic pathways linked to focus, executive function, and psychological well-being under stress. Research confirms improvements in attention and cognitive performance, making this a strong daily support for high-demand mental workloads.*

Hormonal Balance and Vitality

KSM-66 has been shown to support healthy testosterone levels and overall energy in both men and women, contributing to daily vitality and a more balanced stress-to-recovery ratio without disrupting natural hormonal production.*
