Mechanism of Action

Sequesters G-actin monomers (via LKKT motif), modulating cytoskeletal dynamics. Promotes cell migration, angiogenesis via VEGF upregulation, and anti-inflammatory action via downregulation of inflammatory cytokines.

Clinical Applications

  • βœ“Chronic tendon and muscle injuries
  • βœ“Cardiac tissue repair (emerging evidence)
  • βœ“Wound healing β€” particularly dermal
  • βœ“Ocular surface healing
  • βœ“Athletic performance recovery
