Summary
Collagen peptides are short-chain amino acid sequences produced by enzymatic hydrolysis of whole collagen (typically bovine or marine). They serve as bioactive signals that stimulate fibroblasts and chondrocytes to produce new collagen, elastin, and cartilage matrix, supporting skin, joint, bone, and gut health.
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
  • Stimulates skin collagen and elastin production
  • Reduces wrinkle depth and improves skin hydration
  • Supports joint cartilage regeneration
  • Reduces joint pain in osteoarthritis
  • Promotes bone density (stimulates osteoblasts)
  • Improves gut barrier integrity (leaky gut)
  • Supports hair and nail growth
  • Excellent amino acid profile for muscle recovery
  • 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
  • Excellent safety profile as food-derived protein
  • Rare: bloating or GI discomfort at high doses
  • Rare: allergic reaction (bovine or fish allergy)
  • Mild bad taste (some forms)
  • Generally well tolerated
  • Mild injection site reactions
