Collagen peptides, also known as hydrolyzed collagen or collagen hydrolysate, are a popular dietary supplement derived from animal collagen. Collagen is the most abundant protein in the human body, providing structural integrity to skin, bones, tendons, ligaments, and other connective tissues. Collagen peptides are produced by a process called hydrolysis, which breaks down full-length collagen proteins into smaller, digestible protein fragments. This process makes them more bioavailable, meaning they are more easily absorbed and utilized by the body.
These peptides are characterized by a high content of specific amino acids, including glycine, proline, and hydroxyproline, which are crucial for the synthesis of new collagen within the body. While the body naturally produces collagen, this production declines with age, leading to visible signs of aging such as wrinkles, and contribute to joint stiffness. Supplementing with collagen peptides is thought to support the body's natural collagen production by providing the necessary building blocks.
Collagen peptides are typically found in a powdered form that can be easily dissolved in hot or cold beverages and foods. They are generally recognized as safe for consumption. (NIH ODS)
