Browse CatalogCollagen Peptides, also known as hydrolyzed collagen or collagen hydrolysate, are small peptide fragments derived from the enzymatic hydrolysis of collagen protein. Collagen is the most abundant protein in the human body, providing structural support to skin, bone, cartilage, tendons, and other connective tissues. The hydrolysis process breaks down the large collagen molecules into smaller, more bioavailable peptide fragments typically ranging from 2 to 20 amino acids in length.
Research on collagen peptides is extensive and crosses multiple disciplines. Published studies have investigated their effects on skin elasticity and hydration, bone mineral density, joint health, and wound healing in various models. The peptides are rich in glycine, proline, and hydroxyproline, amino acids that are critical building blocks for collagen synthesis. Some research has specifically examined how ingested collagen peptides stimulate endogenous collagen production through a matrikine-like signaling mechanism.
Unlike most of our catalog, which consists of single defined-sequence peptides, Collagen Peptides are a complex mixture. This is inherent to the product and is actually important for its research applications, as the diversity of fragment sizes and sequences contributes to its biological activity profile.
NXPeptides provides high-quality Collagen Peptides with thorough quality testing documentation. Store in a cool, dry place. Once reconstituted or dissolved, keep at 2-8C. See our storage guide for specifics.
