100% Root-Only – No Leaves, No Fillers

Many ashwagandha supplements use a mix of leaves and roots to cut costs, but this dilutes potency and may introduce unwanted compounds. KSM-66 is a true root-only extract, preserving the natural balance of withanolides, which are the key active compounds responsible for its stress-relieving, performance-enhancing, and cognitive-boosting effects. With no unnecessary fillers or synthetic ingredients, you’re getting pure, clinically-proven potency.

Full Spectrum Root Extract - No Need for Bio-Enhancers

Most herbal extracts require bio-enhancers like black pepper (piperine) to boost absorption. KSM-66 is different. It’s naturally optimized for superior bioavailability, thanks to its unique extraction method that preserves the full spectrum of active compounds. This means your body can absorb and utilise KSM-66 efficiently without needing synthetic additives or enhancers.

KSM-66 is produced using a green extraction process, free from harsh chemicals and solvents. It’s ethically sourced and adheres to strict Good Manufacturing Practices (GMP) to ensure purity, potency, and sustainability. Completely vegan, non-GMO, and gluten-free, KSM-66 is crafted to support both your health and the planet.
