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