The Active Ingredient Is: Ashwagandha Extract (KSM-66)

Ashwagandha is a traditional herb used for its adaptogenic properties. The KSM-66 extract is derived from the Withania somnifera root and is presented here as a root-based extract for nutritional support.

This form is produced using Green Chemistry to preserve a full spectrum of bioactives and is supplied in a vegan capsule, with ingredients originating from certified organic material.

What Does Ashwagandha Extract Do?

Ashwagandha extract acts as an adaptogen, supporting the body's natural response to daily stress and helping normal mood and energy regulation. It participates in processes that balance stress-related pathways in the body, in line with general expectations for adaptogenic herbs.

Dr. Chandrasekhar of the Indian Medical Association found that daily KSM-66 supplementation can support healthy stress responses and mood in adults.

Dietary supplements are not a replacement for a balanced diet. Do not take more than the recommended amount. Keep in a cool, dry area away from light and heat. Ensure they are out of children's reach and view.
