Marine Fish Collagen Peptides CAS 9064-67-9

The collagen protein is removed and then broken down into smaller units of protein (or collagen peptides) through a process called hydrolysis (why you'll also hear these referred to as hydrolyzed collagen). These smaller bits make it so marine collagen peptides easily dissolve in hot or cold liquids, which makes it an easy addition to your morning coffee, smoothie, or oatmeal. And yes, it's odorless and tasteless.
As with all sources of collagen, the body doesn't simply absorb marine collagen whole and deliver it directly where it needs to go. It breaks the collagen down into its individual amino acids, which are then absorbed and utilized by the body. While it contains 18 amino acids, marine collagen is characterized by high levels of glycine, proline, and hydroxyproline. It's important to note that marine collagen contains only eight out of the nine essential amino acids, so it's not considered a complete protein.
There are at least 28 "types" of collagen that can be found in the human body, but three types—Type I, Type II, and Type III—comprise about 90%2 of all collagen in the body. Marine collagen contains Types I & II collagen. Type I collagen, specifically, is found all over the body (except for cartilage) and is most highly concentrated in bone, ligaments, tendons, skin, hair, nails, and the gut lining. Type II is mainly found in cartilage. Grass-fed bovine collagen, on the other hand, is high in Types I & III. Type III collagen is found in skin, muscle, and blood vessels. The combination of Type I and III make grass-fed bovine collagen superior for overall health.
