Collagen Peptides (Hydrolyzed Collagen Peptides (Types I, II, III))
Bioactive peptide fragments from enzymatic hydrolysis of collagen protein. Orally bioavailable and stimulate endogenous collagen synthesis in skin, joints, and bones.
How it works
Absorbed as di/tripeptides (Pro-Hyp, Hyp-Gly), accumulate in skin and signal fibroblasts to increase collagen, hyaluronic acid, and elastin production.
Key facts
- Molecular weight: 2,000-5,000 Da (average)
- Half-life: 4-6 hours (plasma peptides)
- Bioavailability: High (oral, >90% absorption)
- Storage: Room temperature, dry, sealed container.
Dosing overview
- Typical dose: 5-15 g
- Frequency: Once daily
- Duration: 8-12 weeks minimum
- Route: Oral (powder/capsule)
Reported benefits
- Improved skin elasticity/hydration
- Reduced wrinkle depth
- Joint pain reduction
- Nail/hair strength
- Bone density support
Possible side effects
- Mild bloating (initial)
- Unpleasant taste (some)
- Rare allergic reaction (marine)
Research
- Oral collagen peptides improve skin elasticity: meta-analysis (2023): Meta-analysis of 19 RCTs confirmed improved hydration (25%) and elasticity (20%) vs placebo.
- Specific collagen peptides improve joint function in athletes (2021): 5g daily reduced activity-related joint pain by 38% over 12 weeks.
