The Active Ingredient Is: Ashwagandha (KSM-66)

Ashwagandha, also known as Withania somnifera, is an adaptogenic herb used to support normal physiological function. The KSM-66 extract is a patented, highly studied form of Ashwagandha root. This formulation is recognised for its clinical testing in hormone-related outcomes.

This extract is a specialised Ashwagandha root preparation that is described as a bioavailable, standardized extract, designed to support ongoing healthy function and balance in the body.

What Does Ashwagandha (KSM-66) Do?

Scientific research suggests that KSM-66 Ashwagandha supplementation can lead to increases in serum testosterone and improvements in muscle strength after eight weeks in healthy men. It also participates in supporting hormonal balance and physical performance in line with EFSA- and NHS-aligned expectations.

Evidence indicates the extract plays a role in normal male hormone function and muscle support, contributing to overall performance and well-being.
