What is Ashwagandha KSM-66®?

An adaptogen with a millennia-old Ayurvedic tradition

Ashwagandha KSM-66® is a high-quality extract from the root of Withania somnifera – a plant that has been valued in Ayurveda for thousands of years. Originally from India, this adaptogen supports the body in adapting to stress and promoting mental balance. The term "adaptogen" describes natural substances that can contribute to stress resistance and general well-being.

Standardized branded extract (15 mg of withanolides per capsule)

KSM-66® is a licensed branded raw material with clinically studied effectiveness. Each capsule contains 300 mg of extract, standardized to 5% withanolides – that's 15 mg of the bioactive plant compounds per dose. This standardization guarantees consistent standards and active-ingredient content in every batch.

Scientifically confirmed benefits and effects

Natural support for stress resistance and balance

The mode of action is based on the natural properties of an adaptogen: this dietary supplement supports stress resistance and promotes mental balance in everyday life. The plant-based active ingredient can contribute to relaxation without causing drowsiness, and helps the body recover after strain. Many users appreciate the calming effect on the mind and nervous system – especially during periods of high demands.

Studies on the effects of KSM-66®

The effects of Ashwagandha KSM-66 have been examined in clinical studies. Research findings show that the branded raw material can support general well-being and contribute to recovery.
