Collagen - All about the protein and its application

No connective tissue without collagen

Collagen isn’t just a term you come across in skincare; it’s also well known amongst athletes. What exactly is collagen, and why is it so popular in these fields? We’ll explain it all in this blog post.

As a naturally occurring protein, collagen is an essential component of connective tissue. It is the most abundant protein in our bodies, accounting for around 25–30 per cent of total protein. Collagen forms a kind of scaffold that holds our bodies together and gives them structure, strength and elasticity.

Structurally speaking, collagen consists of long, fibre-like molecules arranged in bundles. There are various types of collagen, each with its own specific functions and properties. For example, type I collagen is the most common form found in the skin, bones, tendons and blood vessels, whilst type II collagen is mainly found in cartilage tissue.

The main role of collagen is to hold tissues and organs together and strengthen them. In the skin, collagen provides firmness and elasticity. It also supports wound healing by promoting skin regeneration. Furthermore, collagen provides a solid foundation in bones, tendons, ligaments and cartilage.

Over time, the skin’s natural production of collagen declines. Exposure to harmful environmental factors such as UV radiation, smoking and stress can accelerate the breakdown of collagen.

What are the benefits of collagen for the skin?

1. Collagen’s ability to provide elasticity and firmness is particularly valued as we age.
2. Collagen helps to strengthen the skin’s structure.
3. Collagen can bind moisture within the skin, keeping it hydrated and supple. Collagen plays a role in skin regeneration and can support wound healing.
4. The presence of collagen in bones, tendons and ligaments makes it of particular interest to people who engage in intensive sporting activities. Athletes involved in high-intensity sports that place significant strain on bones, tendons and ligaments can benefit particularly from collagen.

Collagen is primarily found in animal products and is mainly derived from animal tissue. The bones and cartilage of cattle, pigs, chickens and fish are particularly rich in collagen. Foods rich in collagen include bone broth, gelatine and certain types of meat and fish with a high proportion of connective tissue. Vegans and vegetarians, in particular, should therefore take special care to ensure they have an adequate intake of collagen.
