The main difference between marine collagen and free range collagen is that wild-caught cod is the source of marine collagen whereas the source of free range collagen is the grass-fed, pasture-raised bovine.
Generally, marine collagen and free-range collagen are two types of collagen supplements that have health benefits for connective tissues in the body. Generally, collagen occurs in the skin, hair, nails, bones, and joints.

What is Marine Collagen
Marine collagen is the collagen extracted from the skin of fish. Generally, people use fish skin and scales for the production of marine collagen. Generally, the type of fish used in the production of collagen includes red snappers and cods. However, the killing of these fish has a negative impact on the environment. The main function of marine collagen is to provide amino acids for building strong and healthy connective tissue in the body.

Furthermore, marine collagen exclusively contains type I collagen. Moreover, the peptide molecules are smaller in size, which makes marine collagen more bioavailable and absorbable. Marine collagen also has hydroxyproline, which is an essential component of skin, blood vessel walls, and other connective tissues. The main health benefits of marine collagen include fewer wrinkles, reducing the signs of aging, and healthier skin.
What is Free Range Collagen
In general free-range collagen is collagen that comes from bovine collagen. After harvesting cattle for meat, their skin is removed and treated for the extraction of collagen. During the process, the collagen from the cattle’s skin hydrolyses into smaller and more digestible amino acids. Moreover, bovine collagen or free-range collagen contains both collagen type 1 and type 3. These collagens are important for the growth and repair of bones, tendons, ligaments, and skin.

Moreover, in order to produce collagen, our body requires amino acids such as glycine and proline. Therefore, collagen is the best source of amino acids. Apart from that, reduced joint pain, improved gut health, better recovery, and increased strength are the health benefits of free-range collagen.
Similarities Between Marine Collagen and Free range collagen
- Marine collagen and free-range collagen are two types of collagen supplements with different sources.
- There are no differences in nutritional value in marine and free range collagen.
- Generally, collagen is important for the health of the skin, hair, nails, bones, and joints.
Difference Between Marine Collagen and Free Range Collagen
Definition
Marine collagen refers to the collagen that comes from the skin of fish while free-range collagen refers to a blend of highly absorbable collagen peptides specifically selected for their ability to promote the healthy collagen structure of our skin, hair, and nails, as well as our joints, bones, and blood vessels.
Source
Usually, wild-caught cod is the source of marine collagen while the source of free-range collagen is the grass-fed, pasture-raised bovine.
Comes from
Marine collagen comes from the skin of fish while free-range collagen comes from the skin of pigs and cows.
Bioavailability
Marine collagen has a higher bioavailability while free-range collagen has comparatively less bioavailability.
Conclusion
In brief, marine collagen and free-range collagen are two types of collagen supplements. Generally, collagen is the most abundant protein that occurs in the connective tissue. It occurs in the skin, hair, nails, bones, and joints. The main feature of marine collagen is its source, which is the wild-caught cod. In comparison, the source of free-range collagen is pigs and cows. However, marine and free-range collagen have no significant difference in nutrition. Therefore, the main difference between marine collagen and free-range collagen is their sources.
