Collagen Peptides

Structural protein for joints, skin elasticity, and connective tissue

Evidence Grade: B — Good clinical evidence Joint & Skin Health
B
Evidence Grade B: Good clinical evidence Based on the volume and quality of published human clinical trials.

Collagen is the most abundant protein in the human body (30% of total protein), forming the scaffolding of skin, bones, tendons, ligaments, and cartilage. Collagen peptide supplements (hydrolysed collagen) provide amino acids — particularly hydroxyproline — that stimulate fibroblasts to produce new collagen. Evidence is accumulating for joint health, skin elasticity, and bone density.

Key Benefits

  • Joint pain & cartilage support
  • Skin elasticity & hydration
  • Bone density (with calcium & D3)
  • Wound healing
  • Muscle mass (with exercise)
  • Nail & hair strength

Best Form

Hydrolysed collagen peptides (Type I & III for skin/nails; Type II for joints); UC-II (undenatured Type II collagen) for joint-specific benefits at very low doses

Dosage

10–15 g hydrolysed collagen/day (skin & general); 40 mg UC-II/day (joints)

⚠ Safety Notes

Safe for most people. Derived from animal sources (bovine, marine, porcine) — not suitable for vegans. May cause mild GI discomfort. Marine collagen preferred by many for taste and sustainability.
