About Collagen Peptides
Collagen is the most abundant structural protein in the body, supporting skin, joints, bones, and connective tissue. Hydrolyzed collagen peptides are broken down for better absorption — low-molecular-weight peptides (2–5 kDa) are best absorbed. Branded bioactive peptides are optimized for specific outcomes: Verisol (2.5 g/day, clinically studied for skin elasticity and wrinkle reduction), Fortigel (5–10 g/day, targeted at cartilage and joint health), and Peptan (general-purpose, broad clinical data across skin, joints, and bones). Marine collagen (from fish) is rich in Type I collagen with smaller peptide size. Generally well tolerated. No established RDA/UL.
What Collagen Peptides supports
- Supports skin elasticity, hydration, and reduces wrinkle depth
- Supports joint comfort and cartilage integrity
- May support tendon and ligament recovery
- Supports nail strength and hair health
- Contains ~33% glycine — at 10g+, delivers the 3g glycine dose studied for sleep quality
How much Collagen Peptides to take
Clinical studies typically use 5–20 g of Collagen Peptides. Most clinical studies use 5–15 g/day of hydrolyzed collagen peptides. Benefits for skin typically seen at 2.5–10 g/day, joint support at 10–15 g/day.
- Effective range
- 5–20 g
Forms of Collagen Peptides compared
- Hydrolyzed collagen peptidesStandardPre-broken into di- and tripeptides for rapid uptake.
- Gelatin (unhydrolyzed)BudgetUnhydrolyzed — larger molecules, lower absorption
Clinical evidence
Moderate clinical evidence. 26+ clinical trials and multiple meta-analyses for skin, joint, and bone outcomes
