Overview

What is Ashwagandha Ksm66?

KSM-66 is a full-spectrum, root-only ashwagandha extract standardized to 5% withanolides, developed by Ixoreal Biomed over 14 years. It is the most clinically-studied ashwagandha extract, with the largest body of human RCTs across stress, sleep, testosterone, and athletic performance.

Key Benefits

Strongest evidence for cortisol reduction and stress relief, reproducible boost in testosterone and DHEA-S in men, improved muscle strength and recovery in resistance-training trials, and modest sleep improvement.

Mechanism of Action

Same multi-target mechanism as base ashwagandha — HPA axis attenuation, GABAergic anxiolysis, antioxidant and anti-inflammatory withanolide effects. Root-only, full-spectrum extract preserves the natural withanolide ratio.

What to Expect

  • Week 1
    Tolerability and dose-response.
  • Week 2-4
    Early effect window.
  • Week 4-8
    Peak benefit assessment.
  • Week 8+
    Cycle decision point.

Side Effects & Safety

Same as parent ashwagandha entry. KSM-66-specific notes:

  • Lower withaferin A than Sensoril → potentially lower autoimmune-flare risk (theoretical)
  • GI upset somewhat less than Sensoril at equivalent withanolide load (anecdotal)
  • Hepatotoxicity case reports exist for ashwagandha generally; KSM-66 has fewer reports than unstandardized products but background rate non-zero
