Collagen Peptides Research Guide

Full name: 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 Collagen Peptides Works

Absorbed as di/tripeptides (Pro-Hyp, Hyp-Gly), accumulate in skin and signal fibroblasts to increase collagen, hyaluronic acid, and elastin production.

Dosing Protocol

• 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

Potential Side Effects

• Mild bloating (initial)
• Unpleasant taste (some)
• Rare allergic reaction (marine)

Research Citations

1. Oral collagen peptides improve skin elasticity: meta-analysis (2023) - Meta-analysis of 19 RCTs confirmed improved hydration (25%) and elasticity (20%) vs placebo.
2. Specific collagen peptides improve joint function in athletes (2021) - 5g daily reduced activity-related joint pain by 38% over 12 weeks.
