Mode of Action

How KSM-66® Works in the Body

KSM-66® supports the body through multiple biological systems involved in stress, mood, and recovery.

Stress Response & Cortisol Regulation

KSM-66® mode of action is proposed to regulate the hypothalamic-pituitary-adrenal (HPA) axis, the system responsible for controlling the body's stress response. By supporting this pathway, it assists in maintaining healthy cortisol levels.

Neurotransmitter Support

KSM-66® is thought to influence key brain chemicals involved in mood and cognition, including:

  • Serotonin (mood balance)
  • Dopamine (motivation and focus)
  • GABA (calmness and relaxation)
Anti-inflammatory & Antioxidant Activity

It also supports the body's natural defence systems by helping reduce oxidative stress and inflammation, which can impact recovery and overall wellbeing.
