As one of the most abundant compounds in the body, collagen is vital to forming the tissues that make up organs, bones and more. Collagen supplements, when taken regularly, have been shown to provide numerous health benefits, including support for bone health, healthy joints, a healthy heart, a normal metabolism, and liver and kidney function. They’ve even been found to promote relaxation and restful sleep.
But today, there are various types of wholesale collagen supplements on the market — and countless benefits to each. Use this guide to learn more about the types of collagen available and the different sources of collagen peptide.
Difference Between Collagen Types 1 2 And 3
There are 28 types of collagen in the body. Out of these 28 types, the first three are the most abundant and readily available on the market. But what are they each responsible for?
The main difference between collagen types 1, 2, 3 is that type 1 and 3 are the most abundant in the human body and increase skin elasticity while strengthening bones and nails. Whereas type 2 collagen is found in joint cartilage and serves as a protective tissue for your bones.
- Type I Collagen is the most abundant in the human body. It makes up 80 percent of the dermis layer of the skin and is thus considered to be the key building matrix protein which gives skin its structure and firmness. Collagen supplements should contain at least 90 percent type I collagen if they’re going to help improve the skin.
- Type II Collagen makes up movable joints and is commonly used to treat joint aging and relieve arthritis pain.
- Type III Collagen is the second most abundant collagen in human tissue. As we age, type III collagen is gradually replaced by type I collagen.
Where Do Collagen Supplements Come From?
There are four primary sources of collagen found in most common supplements: bovine (cow), chicken, porcine (pig) and marine (fish) collagen.
Made of the skin, bones and muscles of cows, bovine collagen is rich in type I and type III collagen. Beef collagen peptides are excellent for maintaining bone and gut health, healing wounds and promoting strong joints. They’re also a rich source of proline and glycine, both of which help reduce fatigue and even repair sun-damaged skin.
Chicken collagen, a type II collagen, is loaded with joint-healthy chondroitin sulfate and glucosamine sulfate – both great for supporting joints and maintaining healthy pH levels. The type of protein that comes from chicken collagen supplements, like eggshell membrane capsules, is also used to treat arthritis, back and neck pain, and even pain caused by surgery.
Like bovine collagen, porcine (pig) collagen (found in both type I and type III collagen) can typically be obtained at a lower cost and is commonly used in cosmetics.
Extracted from fish, marine collagen (type I) is absorbed up to 1.5 times more efficiently into the body. The body’s cells can easily absorb fish gelatin and use it to keep skin tight and wrinkle-free. Due to its digestibility, fish collagen is excellent for digestive issues or to heal the gut. While marine collagen is more costly, it can be more effective because it’s absorbed by the body up to 1.5 times as easily as cheaper bovine and porcine collagen.
