Larazotide Acetate
Summary
AICAR is a cell-permeable AMP analog that activates AMPK (AMP-activated protein kinase) — the master metabolic switch that triggers fat burning, mitochondrial biogenesis, and adaptations normally only achieved through exercise. It has been called the 'exercise in a pill' compound.
Larazotide acetate is an 8-amino acid peptide (Gly-Gly-Val-Leu-Val-Gln-Pro-Gly) derived from Zonula Occludens Toxin (ZOT) of Vibrio cholerae. It paradoxically acts as a ZOT antagonist to close tight junctions and reduce intestinal permeability ('leaky gut'). It is the most advanced clinical compound targeting gut permeability directly.

Key Benefits
  • AMPK activation mimics aerobic exercise adaptations
  • Increased fat oxidation and endurance
  • Mitochondrial biogenesis (PGC-1alpha)
  • Improved insulin sensitivity and glucose metabolism
  • Anti-inflammatory effects
  • Potential cardiac protection during ischemia
  • Synergistic with actual exercise training
  • Reduces hepatic glucose production
  • Directly reduces intestinal tight junction permeability
  • Clinical efficacy in celiac disease (Phase 3 trials)
  • Reduces systemic inflammation from gut permeability
  • Targets root cause of leaky gut (Zonulin pathway)
  • Local gut action without systemic absorption
  • Potential application in IBS, IBD, autoimmune conditions
Side Effects
  • Hypoglycemia risk
  • Lactic acidosis at high doses (animal data)
  • Injection site irritation
  • Headache (mild, dose-dependent)
  • Nausea (rare)
  • Well-tolerated overall in clinical trials
