Dihexa vs Glutathione

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

Cognitive Enhancement
Dihexa
Anti-Aging & LongevityImmune Support
Glutathione
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.
Glutathione is the body's master endogenous antioxidant tripeptide, composed of glutamate, cysteine, and glycine. It neutralizes reactive oxygen species, supports detoxification in the liver, recycles other antioxidants (vitamins C and E), and plays a central role in immune function, DNA repair, and cellular redox balance.

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
  • Primary endogenous antioxidant and free radical scavenger
  • Supports hepatic detoxification of xenobiotics and heavy metals
  • Recycles vitamins C and E to maintain antioxidant network
  • Modulates immune function and T-cell activity
  • Skin brightening via inhibition of tyrosinase (IV/topical routes)
  • Neuroprotective in oxidative stress-related conditions
  • Mitochondrial protection and energy metabolism support
Side Effects
  • Headache
  • Irritability
  • Brain fog during washout period
  • Unknown long-term effects (insufficient data)
  • Oral bioavailability is limited (largely hydrolyzed in gut); liposomal or sublingual forms preferred
  • IV administration: rare allergic reactions, vein irritation
  • High-dose supplementation may cause zinc depletion over time
  • Inhaled glutathione may trigger bronchoconstriction in asthmatics
