Different Types of Collagen and its Functions

Different Types of Collagen and its Function

Collagen makes up about 30% of the protein in your body. It plays a crucial role in giving your skin, muscles, bones, and connective tissues their shape and strength. 

Collagen is getting all the hype these days, but do you really know what it does for your body? We’re here to break it down for you. From the types of collagen to how it works in your body, plus some treatments to amp up your skin’s collagen game, we’ve got you covered in this blog. 

What is Collagen? 

3 Types of Collagen

Collagen is a vital protein in the human body, serving as a foundational component. It plays a key role in giving structure and strength to our skin, muscles, bones, tendons, and various connective tissues. Collagen is also present in organs, blood vessels, and the intestinal lining. 

This essential protein is formed from specific amino acids, including proline, glycine, and hydroxyproline, which combine to create strong protein fibrils in a triple helix structure. Adequate levels of vitamin C, zinc, copper, and manganese are essential to support the production of this critical protein in the body.

3 Primary Types of Collagen and Their Functions

We often think of collagen as just one thing. However, there are actually 28 different types of collagen. But for most of our concerns, we mainly focus on three primary collagen types and their functions.

1. Collagen Type I

Collagen Type I makes up most of the body’s collagen, accounting for up to 90% of it. It’s composed of tightly packed fibres. This collagen type is responsible for providing structure to various parts of the body, such as the skin, bones, tendons, cartilage, connective tissues, and teeth.


Interestingly, natural levels of collagen type I in the body begin to decrease in our twenties. Because collagen type I is abundant in connective tissues, a decrease in its levels can lead to less firm skin, fragile nails, thinning hair, and the development of fine lines and wrinkles.

2. Collagen Type II

Collagen Type II has a different structure, with fibres that are more loosely packed and typically found in elastic cartilage. This type of collagen acts as a cushion for your joints, aiding in their mobility and function. It’s often included in supplements to support the skeletal system. Collagen Type II consists of long, identical chains of amino acids that form a dense network of fibres. This network provides cartilage with the strength and flexibility necessary to withstand mechanical stress and absorb shocks. Adding collagen type II to your body can assist in managing the wear and tear that your joints experience.

3. Collagen Type III

Collagen Type III plays a crucial role in maintaining the structure of muscles, organs, and arteries in the body. It’s the second most abundant type of collagen and is typically present in reticular fibres like those found in the bone marrow.

What are the Different Sources of Collagen? 

Collagen can be sourced from various places, and the collagen from each source has unique properties and can be found in different parts of the body.

  • Marine collagen is taken from fish bones, skin, and scales. It’s believed to be particularly good for the skin and bones
  • Bovine collagen comes from cows and is thought to be helpful for joint health
  • Vegetarian or vegan collagen isn’t “true” collagen because it doesn’t come from animals. However, it’s believed to encourage your body to produce its own collagen naturally
  • Hydrolysed collagen is collagen that’s been broken down into smaller pieces to make it easier for your body to absorb into your bloodstream
  • Gelatin is similar to collagen but not quite the same. It’s made from animal bones, typically by boiling them. However, our bodies can’t directly absorb collagen from gelatin
