5 safety notes
Small collagen-derived peptides (e.g., Gly-Pro-Hyp) absorbed into the bloodstream are proposed to signal dermal fibroblasts to synthesize new collagen, elastin, and hyaluronic acid, improving skin firmness and reducing wrinkle depth.
Dose: 1–5 g
Tested as: hydrolyzed collagen peptides; most positive trials used the patented bioactive collagen peptide Verisol (GELITA AG) at 2.5-5 g/day for 8 weeks; one independent-brand trial used 1 g/day of a different, fish-derived low-molecular-weight collagen peptide for 12 weeks
