Collagen peptides are broken-down fragments of collagen — the most abundant protein in your body. Our research, from 3 meta-analyses and 3,137 participants, shows they modestly improve skin elasticity, reduce wrinkles, improve osteoarthritis symptoms, and may support muscle strength when combined with exercise. The evidence is moderate but consistent. Collagen is safe and well-tolerated with essentially no known drug interactions.
