About this supplement
Marine collagen peptides are hydrolyzed collagen proteins derived from marine sources, primarily fish skin, scales, and bones. They consist of short-chain amino acid sequences (peptides) produced through enzymatic hydrolysis of native collagen, resulting in high bioavailability and solubility. This form of collagen is rich in glycine, proline, and hydroxyproline, which are essential for connective tissue synthesis. Unlike bovine or porcine collagen, marine collagen is primarily Type I collagen and is often marketed for its smaller molecular weight, which may enhance absorption. It is commonly used in dietary supplements and nutricosmetics for skin, joint, and bone health.

Physical properties
Typically a fine, white to off-white powder with little to no odor. Highly soluble in cold water, forming clear or slightly opalescent solutions. Hydrophilic and hygroscopic. Molecular weight ranges from 2–10 kDa due to hydrolysis.
How it’s made
Produced by cleaning and processing fish by-products (skins, scales, bones). Collagen is extracted using acid or alkaline treatment, then enzymatically hydrolyzed (e.g., with proteases like trypsin or pepsin) to break long collagen chains into short peptides. The hydrolysate is filtered, purified, concentrated, and spray-dried into powder.
