Full-spectrum ashwagandha root extractKSM-66® Ashwagandha
The root-only, full-spectrum ashwagandha extract.
Brand / technology by Ixoreal Biomed
KSM-66® is the ashwagandha root extract in our capsules. Research on this ingredient includes studies of stress and sleep. We chose a root-only extract with a consistent 5% withanolide concentration.
Why this matters
A researched ashwagandha root extract in two daily capsules.
- Made from the root
KSM-66® uses ashwagandha root, with no leaf extract. It is standardised to 5% withanolides, naturally occurring plant compounds.
- What the research looks at
One placebo-controlled study followed 64 adults with a history of chronic stress for 60 days, measuring perceived stress and cortisol. The studies below explain the findings for this extract; they did not test our finished capsules.
- How it fits into your day
Two capsules provide 600 mg KSM-66®, including 30 mg withanolides.
The technology
KSM-66® is standardised to ≥5 % withanolides (measured by HPLC) and is produced with a proprietary “Green Chemistry” extraction — water-based, with no alcohol or chemical solvents. “Full-spectrum” means it aims to keep the natural balance of the root’s constituents rather than concentrating a single fraction.
A large clinical program
KSM-66® has been used in multiple randomised, double-blind, placebo-controlled human trials. The sources below describe the participants, duration and measurements.
