Source: Wild-caught North Atlantic deep-sea cod skin.

Collagen Type: Pure Type I collagen — the same type that makes up over 90% of human collagen, found in skin, bones, tendons, blood vessels, and joints.

Molecular Weight: Under 600 Daltons — nearly half the industry standard of 1,000 Daltons for low-molecular-weight peptides. Small enough to be absorbed directly through the intestinal wall without requiring digestion.

Bioavailability: 95%. The peptide chains enter the bloodstream intact rather than being broken down into individual amino acids.

Amino Acid Profile: Contains all 8 essential amino acids, including tryptophan — absent in porcine, bovine, and freshwater fish collagen. Tryptophan is the precursor to serotonin and melatonin, supporting both mood and sleep regulation.

Purity: 99%, achieved through six-stage directional enzymatic hydrolysis and multi-membrane nanofiltration.

Applications:

Oral beauty and skin hydration
Joint and cartilage health
Vascular endothelial repair
Bone density support
Post-surgery and postpartum recovery
Certifications: GMP · ISO · FDA Registered

Available as: Bulk raw powder, finished supplement sachets, or OEM/ODM custom formulations.

Factory: 100,000 sqm production park with 28 national invention patents. Direct factory supply. No middlemen.
