Collagen, What Is It?

Updated: Sep 15




Collagen is the most abundant protein in the human body. There are actually 28 different types of collagen, but today we are going to be discussing the three most prominent and important!


But what is collagen? If you have any kind of connective tissue disorder, specifically EDS/HSD, you have probably heard it numerous times. For those with EDS/HSD, there is a weakening in the collagen, and can be due to insufficient amounts of structurally normal collagen, or for those with Classical EDS, a mutation in type V collagen (which we will discuss another day!)


Type I collagen makes up to 90% of your body’s collagen. It can be found in the skin, bones, blood vessel walls, and in the connective tissue and fibrous cartilage. Type I collagen is also found in scar tissue, and it has been suggested that it aids in wound healing and blood clotting. It is often revered for its anti-aging properties but is also incredibly beneficial for those with connective tissue disorders. Type I collagen can be found in egg whites, protein rich foods like fish and beef, bone broth, and marine collagen.


Type II collagen is like the elastic sister of Type I collagen, as it is known for promoting joint and tendon health, and is known for treating joint pain. Studies show that in patients with rheumatoid arthritis showed that the majority of patients experienced some kind of joint relief. Out of all of the collagen supplements, type II has been shown to last in the digestive system longer than the other types of collagen, and can be found in bone broth, protein rich foods, and collagen peptide powders.


Type III collagen provides and improves the makeup of our muscles, as well as organs and blood vessels. This is the second most prevalent type of collagen in the body behind type I. This collagen is particularly abundant in the intestines, and studies are being conducted to test this point. Like the other types of collagen, the best sources for this type III is bovine collagen peptides, protein rich foods like beef and fish, bone both, egg whites, and collagen peptide powder.


Dr. Perretto recommends the Vital Proteins brand of collagen peptides, since their formula includes a high concentrate of type I and type III collagen. But if you want an extra kick of type II, they also offer the cartilage collagen!
