Collagen peptides are bioactive fragments derived from collagen, the most abundant protein in the human body, primarily sourced from animal connective tissues. Researchers primarily study collagen peptides for their potential benefits in enhancing connective tissue recovery, improving skin health, and supporting bone density. Key findings indicate that collagen peptide supplementation may reduce pain and improve function in active adults, while also promoting dermal matrix synthesis and reducing skin wrinkles in aging populations. Additionally, studies suggest that specific collagen peptides can positively influence bone mineral density and markers of bone formation in postmenopausal women. Current research is ongoing to further elucidate the mechanisms and benefits of collagen peptides across various health domains.
