Primary Benefits:

  • Reduces anxiety and promotes a calm mental state
  • Enhances mental clarity and emotional balance
  • Supports restorative sleep and mood stabilization
  • Improves focus by reducing stress-induced distraction

Mechanism of Action:
Selank is a synthetic heptapeptide derived from the naturally occurring tetrapeptide tuftsin. It modulates the balance of neurotransmitters such as serotonin and dopamine and exerts anxiolytic effects by enhancing the inhibitory action of GABA. It also promotes neurotrophic factors and has been shown to improve BDNF expression, contributing to cognitive resilience.
