Marine Collagen (Type I)
What is Marine Collagen (Type I)?
Marine Collagen (Type I) is a protein derived from the scales or skin of fish. It is primarily composed of Type I collagen, which is commonly found in human skin, tendons, and bones. The extraction process involves enzymatic hydrolysis to break down the protein into smaller peptides that are more easily absorbed by the body.
This ingredient is used in supplements and beauty products due to its potential benefits for skin health and joint function. However, scientific evidence on its efficacy is mixed. Some studies suggest it may help improve skin elasticity and hydration, while others call for more rigorous research to confirm these effects.
When you see Marine Collagen (Type I) on a label, it typically indicates the product is targeting skin or joint health, but keep in mind the potential variability in individual results.
Commonly found in: Dietary supplements, Beauty creams, Protein bars, Skin serums
Benefits
- May improve skin elasticity and hydration.
- Could support joint health and function.
Marine collagen is not subject to specific FDA regulation as a dietary supplement ingredient but is generally recognized as safe (GRAS).
Some studies suggest benefits for skin and joint health, but more extensive, controlled studies are needed to validate these claims.
Marine collagen is animal-derived and therefore not suitable for vegan consumers.

Scout's take
Marine collagen is predominantly Type I — the most abundant collagen in skin, hair, nails, and bones. Its smaller peptide size gives it higher bioavailability than bovine Type I.
