Collagen peptidesClinical evidence

Hydrolysed collagen

Hydrolysed collagen fragments taken orally — among the best-studied supplement peptides — researched for skin aging, joints and connective tissue.

⚙️ How it works

Hydrolysis yields bioavailable di/tri-peptides (notably proline-hydroxyproline) absorbed intact. These both supply collagen building-blocks and act as signalling molecules that stimulate fibroblasts and chondrocytes to upregulate collagen, elastin and hyaluronic acid.

🎯 What it's studied to help

Bars reflect the strength & volume of research evidence for each use — not a guarantee of results.

Skin72/100
Randomised human trials show improved elasticity, hydration and reduced wrinkle depth.
RCTs and meta-analyses support reduced joint pain and better connective-tissue outcomes.
Hair35/100
Provides amino-acid substrate with some trial signal for hair/nail quality.
With resistance training, shows modest lean-mass/strength gains, especially in older adults.
Back pain20/100
Indirect connective-tissue support only; little direct back-pain evidence.
