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.
KPV is a naturally occurring anti-inflammatory tripeptide derived from the C-terminal of alpha-MSH. It powerfully suppresses intestinal and systemic inflammation via melanocortin receptors, making it valuable for IBD, gut healing, and wound repair.
Half-Life
N/A — food-derived; absorbed peptides circulate for hours, depot accumulation in tissues
Short half-life (~15–30 minutes), but effects persist longer due to receptor-level anti-inflammatory cascades

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
  • Reduces intestinal inflammation (IBD, Crohn's, colitis)
  • Promotes gut mucosal healing and barrier integrity
  • Accelerates wound healing topically
  • Suppresses systemic inflammatory cytokines
  • Antimicrobial properties against pathogens
  • Reduces neuroinflammation when administered systemically
  • May improve symptoms of inflammatory skin conditions
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 very well tolerated
  • Mild injection site reactions (SC)
