Thymagen
Summary
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.
Thymagen is a dipeptide bioregulator (Glu-Asp) developed by Professor Vladimir Khavinson, tissue-specific for the thymus gland. It supports T-lymphocyte maturation, thymic function, and immune system normalization. As the thymus involutes with age (thymic atrophy), immune competence declines. Thymagen is used to support immune restoration, particularly in aging, post-illness recovery, and immunodeficiency states.

Key Benefits
  • 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
  • Supports thymic epithelial cell function and T-cell maturation
  • May partially restore thymic output reduced by age-related atrophy
  • Normalizes T-lymphocyte subpopulation balance
  • Supports immune recovery after illness, surgery, or chemotherapy
  • Anti-aging effects on thymic tissue
  • Complementary to Thymosin Alpha-1 and Thymalin in immune protocols
  • May improve vaccine responsiveness in older individuals
Side Effects
  • 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
  • Generally well tolerated
  • Mild injection site reactions
  • No significant immunological adverse events reported
