Summary
Livagen is a dipeptide bioregulator (Lys-Glu) developed by Professor Vladimir Khavinson, tissue-specific for the liver and thymus. It supports hepatocyte function, promotes liver cell regeneration, and modulates immune function via thymic activity. Research suggests benefits in chronic liver disease, hepatic aging, and immune restoration following liver damage.
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.

Key Benefits
  • Supports hepatocyte regeneration and liver tissue repair
  • Normalizes liver cell protein synthesis
  • Immune modulation via thymic activity
  • Potential benefits in chronic hepatitis and liver aging
  • Anti-aging effects on hepatic tissue
  • May support liver recovery after toxic insult or alcohol damage
  • Complementary to NAD+ and glutathione in liver health protocols
  • 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
Side Effects
  • Generally well tolerated
  • Mild injection site reactions
  • No significant hepatotoxic effects reported at standard doses
  • 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)
