Collagen - All about the protein and its application

No connective tissue without collagen

Collagen is not only a term familiar in skincare but is also well known among athletes. What exactly is collagen and why is it so popular in these areas? We explain it 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, making up around 25–30% of total protein. Collagen forms a sort of scaffold that holds our body together and gives it structure, strength and elasticity.

Structurally, collagen consists of long, fibrous molecules arranged into bundles. There are different types of collagen, each with its specific functions and properties. For example, type I collagen is the most common in skin, bone, tendons and blood vessels, while type II collagen is found mainly in cartilage tissue.

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

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

What benefits does collagen have for the skin?

1. The ability of collagen to provide elasticity and firmness is especially valued as we age.
2. Collagen helps to strengthen the skin’s structure.
3. Collagen can bind moisture in the skin and keep 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 interesting for people who engage in intense sport. In particular, athletes in high-impact, power sports that place heavy loads on bones, tendons and ligaments can benefit from collagen.

Collagen is found mainly in animal products and is primarily sourced from animal tissue. Bones and cartilage from cattle, pigs, poultry and fish are particularly rich in collagen. Collagen-rich foods include bone broth, gelatin and certain cuts of meat and fish with a high connective tissue content. People following a vegan or vegetarian diet should therefore pay particular attention to ensuring adequate collagen intake.
