Dihexa vs Teduglutide

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

Cognitive Enhancement
Dihexa
Recovery & Repair
Teduglutide
Summary
Dihexa is a potent experimental oligopeptide derived from angiotensin IV that dramatically enhances synaptogenesis. Preclinical research shows cognitive enhancement orders of magnitude more potent than BDNF — it is considered one of the most powerful nootropic compounds in research, but has very limited human safety data.
Teduglutide is a GLP-2 (glucagon-like peptide-2) analog with enhanced stability. Unlike GLP-1, GLP-2 specifically acts on the intestinal epithelium to increase intestinal length, villus height, and absorption surface area. FDA-approved as Gattex for short bowel syndrome, it is also being investigated for IBD, leaky gut, and mucosal healing.

Key Benefits
  • Dramatically increases synapse formation (potentially 10 million× more potent than BDNF in animal models)
  • Enhances memory and learning
  • May reverse cognitive decline
  • Improves neuroplasticity and executive function
  • Long-lasting cognitive benefits from short courses
  • Potential therapeutic agent for Alzheimer's
  • Increases intestinal villus height and absorption surface area
  • Reduces intestinal permeability (leaky gut)
  • FDA-approved for short bowel syndrome
  • Reduces parenteral nutrition dependence in SBS patients
  • Promotes intestinal mucosal healing in IBD
  • Increases tight junction proteins ZO-1 and occludin
Side Effects
  • Headache
  • Irritability
  • Brain fog during washout period
  • Unknown long-term effects (insufficient data)
  • Injection site reactions
  • Abdominal pain and bloating
