Bovine vs Marine Collagen
Collagen powders and supplements have been on the beauty and diet markets for some time now. Many people are still curious as to whether or not they are worth the money or how collagen will benefit their health, well find your answers here! Collagen is a key protein found in connective tissue. Itis the most abundant protein in the body. Its fiber-like structure is used to make connective tissue. Like the name implies, this type of tissue connects other tissues and is a major component of bone, skin, muscles, tendons, and cartilage.
There are two types of collagen being used in the diet and nutrition industry: bovine (cow) and marine (fish and shellfish). Collagen is a protein that comes from the bones and connective tissue of these animal sources. There are over 20 types of collagen that exist in your body, each with a specific role. The main types are collagen I, II, III, and IV. Bovine collagen contains types I and III collagen, while marine collagen contains types I and II.
Once consumed, via supplement pill or powder, collagen is digested in the stomach. Collagen is broken down just like any other protein: into smaller molecules called amino acids. All amino acids will be used by the body later to build more proteins. Therefore, if there are more abundant amino acids that can be used to make collagen for our own bodies than supplementation may increase the collagen production within our bodies.
“The collagen in your skin is primarily made up of types I and III collagen, meaning that bovine collagen may be especially useful for reducing wrinkles, promoting elasticity, and increasing skin moisture.”
There is some evidence that suggests that marine collagen “…carries a lower risk of transmitting diseases, has fewer inflammatory effects, and boasts a higher absorption rate than bovine collagen.” Although bovine collagen has been used for a longer period of time and has had more research supporting its health claims such as possibly alleviating osteoarthritis symptoms, decreasing signs of aging, and preventing bone loss (which happens with age).
Although non-industry funded research on collagen supplements is lacking, some “… doctors believe that other treatments like retinol, tretinoin, and vitamin C might provide more benefits by helping your body make the collagen protein.”
Overall there are benefits to both marine and bovine collagen supplements. Each can support our connective tissue health, but just as with any supplement it should not be consumed instead of healthy collagen-containing food sources like lean meats and fish. Also, “it's important to note that supplements are not regulated by the FDA, so if you're thinking about using either as a supplement or a cream, talk with your doctor about it first to make sure it's right for you.”
