Marine Collagen Peptide

Marine Collagen Peptide is a Type I collagen peptide produced by enzymatic hydrolysis of fish skin, principally from tilapia, cod, and pangasius. Delivers low-molecular-weight peptides (typically 1,500 to 3,000 Da) with high cold-water solubility and minimum 90 percent protein on a dry basis.

Protein content of 90 percent minimum (Kjeldahl, N x 5.55), with average molecular weight typically lower than bovine or porcine peptides at 1,500 to 3,000 Da, supporting rapid absorption. Light yellow to off-white free-flowing powder with neutral to mild marine note depending on grade.

The amino acid profile is the collagen signature: glycine, proline, and hydroxyproline dominant. Marine collagen carries the highest skin-permeability profile among the commercial collagens in cosmetic application studies and is the preferred peptide for beauty-from-within positioning.

We supply food-grade and cosmetic-grade Marine Collagen Peptide from manufacturers in China holding ISO, HACCP, Halal, Kosher, and other certifications relevant to the product and production. Halal certification is straightforward as the fish raw materials are inherently compliant.

Common market grades include standard 90 percent protein marine peptide at 2,000 to 3,000 Da, premium ultra-low-molecular-weight grades at 1,000 to 1,500 Da, deodorized cosmetic grade with extensive odor management, and instant cold-soluble grades for ready-to-drink beverages. Bulk and reduced-MOQ shipments. Batch-level COA covering protein, molecular weight, hydroxyproline, heavy metals (particularly mercury given marine origin), and microbiology.

Marine collagen extraction scaled commercially in East Asia in the 2000s and entered global premium supplement markets in the 2010s. The category grew rapidly with the rise of beauty-from-within positioning and consumer preference for non-mammalian protein sources.

Manufacturing begins with fish skin, principally from tilapia, cod, and pangasius aquaculture and processing. The skin is cleaned, demineralized, and pretreated under controlled acid or alkali conditions to swell the collagen. Thermal extraction releases gelatin into solution. The gelatin is then enzymatically hydrolyzed with food-grade proteases to a target molecular weight, deodorized using activated carbon or chromatographic technology to address marine-note flavor, filtered, evaporated, and spray-dried.

Regulated as a permitted food ingredient under U.S. FDA GRAS provisions, regulated under EU food law, and free of BSE concerns associated with bovine material. Listed as one of the 14 EU declarable allergens (fish) on finished product labels.

Amino acid quality positioning: functionally equivalent to bovine and porcine collagen on the bioactive peptide level, with a typically lower molecular weight profile that supports faster absorption and higher skin permeability in cosmetic applications.

Strategic positioning: marine collagen carries a premium price relative to bovine and porcine collagen and is the dominant collagen source in premium beauty supplements, Halal markets, Kosher markets, pescatarian formulations, and cosmetic applications.
