Thymosin Alpha-1
Summary
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.
Thymosin Alpha-1 is a naturally occurring 28-amino acid peptide derived from the thymus gland. It is a powerful immune modulator approved in many countries for treating chronic hepatitis B, hepatitis C, and as an adjunct in cancer immunotherapy.

Key Benefits
  • 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
  • Enhances T-cell and NK cell activity
  • Supports recovery from viral and bacterial infections
  • May reduce inflammation systemically
  • Supports healthy aging and immune resilience
  • Improves vaccine response
  • Supports liver health
  • May help with chronic fatigue syndrome and post-viral conditions
  • Approved in multiple countries for hepatitis B and C treatment
Side Effects
  • Headache (mild, dose-dependent)
  • Nausea (rare)
  • Well-tolerated overall in clinical trials
  • Injection site irritation
  • Mild flu-like symptoms initially (immune activation)
  • Fatigue (rare)
