How are we different?
Our KSM-66® ashwagandha extract is derived exclusively from the roots of the plant and contains no leaves. The leaves of the ashwagandha plant contain other ingredients, such as withaferin A, which is not present in our pure root extract. The KSM-66® extract provides the highest naturally achievable withanolide content of 5% from a pure root extract. It delivers the full spectrum of withanolides from the root in their natural ratio. Higher concentrations can only be achieved by mixing with other extracts and no longer correspond to the natural composition of ashwagandha root. The KSM-66® extract is produced entirely without ethanol and other solvents, as is common with many extracts. In our production, we also forgo the usual milk pre-treatment of the ashwagandha roots, making the extract perfectly suitable for vegans. The manufacturer of KSM-66® is the only ashwagandha producer in the world with its own farms, production facilities, laboratories and research centres.
For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We use environmentally friendly amber glass jars for the packaging of this product.

Ashwagandha
Ashwagandha
Ashwagandha (Withania somnifera) is a plant from the nightshade family. The name comes from Sanskrit and roughly translates as "smell of horse," as the roots have a strong scent that is reminiscent of horses. The term "somnifera" comes from Latin and can be translated as "sleep inducing" (somnus = sleep, ferre = to bring), hence its nickname as the "sleeping berry." In this formula, the roots and leaves of the ashwagandha plant are used and not the berry, which is poisonous in large quantities due to its alkaloid content and has a very bitter taste. The roots and leaves contain withanolides, the most widely studied phytochemicals in ashwagandha. These belong to the group of steroidal lactones and are similar to steroid hormones in their chemical structure.
