What is collagen?

Collagen is a protein that our body produces. Our joints, bones, muscles, tendons, as well as hair and nails, are made up of collagen. In fact, 30% of all proteins in our body are collagen. In other words, collagen is essential and plays a crucial role in our entire body. It forms the basis for all connective tissues in the human body and can be compared to a kind of glue that holds the body together. It is essential for maintaining the structure and strength of connective tissue. Collagen proteins, also known as collagen peptides, for example, provide cohesion, firmness, and elasticity to our body and are responsible for regenerating cartilage. Moreover, it ensures strong nails, less hair loss, and flexibility of muscles and joints. When tissues are damaged, the body needs collagen to repair and strengthen.


From the age of 25, the natural production decreases, and the quality of the collagen produced by the body slowly deteriorates. As a result, the skin ages, wrinkles appear, and skin elasticity decreases. Fortunately, there is also good news: you can boost and increase your collagen production by taking our collagen supplement.


Innerfit uses type 1 collagen peptides (Peptan®) enriched with vitamin C. These type 1 collagen peptides are identical to the natural peptides found in the human body and are the same type found in our skin, hair, nails, tendons, and bones. It is an essential building block that ensures healthy skin, hair, nails, muscles, tendons, bones, and joints from within. Moreover, vitamin C contributes to the normal formation of collagen and helps to firm the skin.



  • Healthy and firm skin: Collagen helps maintain the firmness and elasticity of the skin. As we age, natural collagen production decreases, which can lead to wrinkles, fine lines, and sagging skin.
  • Less hair loss and stronger nails: Collagen is also essential for strong nails and shiny, healthy hair. It supports the growth and structure of these keratin-rich tissues.
  • Muscle building and recovery: Collagen plays a significant role in promoting muscle building by supporting the structure and strength of muscles, while also helping to speed up the recovery process after intense workouts by promoting the repair of damaged muscle fibers.
  • Healthy joints and stronger bones: The collagen in our joints provides lubrication and support, allowing us to move smoothly without discomfort or stiffness. Moreover, it plays a role in maintaining healthy, strong bones and helps reduce the risk of bone loss and osteoporosis.
  • Good gut health and a stronger immune system: Collagen supports good gut health by improving intestinal wall integrity, making nutrient absorption more efficient, and reducing inflammation. This contributes to a stronger immune system as healthy gut flora and optimal nutrient absorption are essential for a well-functioning immune system.


The different types of collagen:

There are over 28 different types of collagen, each offering specific benefits. Collagen peptides type 1 and type 2 are by far the most important in our bodies. Moreover, 90% of the total collagen contains collagen peptides type 1. Each type has its characteristics and occurs in the body.

  • Collagen type 1 is found in the skin, hair, nails, bones, cartilage, connective tissue, ligaments, tendons, and blood vessels.
  • Collagen type 2 is found in the joints, intervertebral discs, ribs, nose, larynx, and trachea.
  • Collagen type 3 is found in the skin, blood vessels, and tissues for wound healing.

Our Innerfit collagen products contain collagen peptides type 1. This type of collagen is an essential building block and contributes to healthy skin, hair, nails, muscles, tendons, bones, and joints. Breakdown of this collagen type 1 leads to wrinkles, hair loss, brittle nails, and age-related discomforts.
