Collagen Peptide
Full name: Hydrolyzed Collagen
Short peptides (primarily dipeptides and tripeptides such as Pro-Hyp and Hyp-Gly) derived from enzymatic hydrolysis of collagen. Oral supplementation studies suggest potential benefits for skin elasticity, joint cartilage, and bone density. Among the few peptides with clinically demonstrated oral bioavailability due to their small size and resistance to gastric breakdown.
