Larazotide Acetate vs NAD+

Side-by-side comparison of key properties, dosing, and research.

Recovery & Repair
Larazotide Acetate
Anti-Aging & Longevity
NAD+
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.
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in all living cells that declines dramatically with age. It is critical for energy metabolism, DNA repair, and sirtuin activation. IV and subcutaneous NAD+ supplementation is used in anti-aging protocols and addiction recovery programs.
Half-Life
Local gut action; minimal systemic exposure
Varies by route; IV provides direct cellular delivery

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
  • Restored cellular energy production (ATP)
  • Sirtuin activation for longevity and metabolic regulation
  • Enhanced DNA repair capacity
  • Improved mitochondrial function and biogenesis
  • Cognitive clarity and mental energy
  • Reduced inflammation
  • Addiction withdrawal support (opioids, alcohol, benzodiazepines)
  • Improved sleep quality
  • Enhanced athletic endurance
Side Effects
  • Headache (mild, dose-dependent)
  • Nausea (rare)
  • Well-tolerated overall in clinical trials
  • Flushing and warmth during IV infusion
  • Nausea during rapid IV administration
  • Chest tightness (from rapid infusion — slow the rate)
  • Injection site irritation (subcutaneous)
