Collagen fibres are basically the scaffolding for all tissues in the body. They keep your skin, internal organs and even your bones in shape and prevent them from collapsing.

Without collagen fibres, we would look very... plastic. This is because they play a significant role in our body. They make up about 30% of the total weight of proteins in the body and are present in skin, bones, cartilage, muscles and joints, among others. Below you will find everything you need to know about them.

From this article you will learn:

How collagen fibres are built.
Where they are found in the body.
How they are formed and what you can do to rebuild them.

What are collagen fibres?

To get a good understanding of what collagen fibres are, you have to start at the beginning, i.e. with the cell. Or, more precisely, what it isn't. Surely you have come across the term cells of the human body many times. However, our body is made up of more than just them.

The non-cellular part of our tissues is the extracellular matrix. Its main components are fibrous elements - primarily collagen fibresand

Collagen fibres are therefore extracellular matrix fibres and are composed of collagen glycoproteins (or in human terms, collagen proteins). Breaking the collagen fibre into even smaller fragments yields strands of collagen peptides, and going even further individual amino acidsand

This breaking down/disintegration of collagen fibres when exposed to water is called the process of hydrolysis.

Ilona Krzak Master of Pharmacy

Collagen fibres are characterised by their elongated structure and the fact that they are strong and insoluble in water. In our body, they are usually arranged in bundlesand

Indeed, gram for gram, type I collagen is stronger than steel.

Molecular Cell Biology, 6th Edition(Lodish et al., 2007)

Collagen fibres under the microscope

This is what collagen fibres look like under an electron microscope:

Functions of collagen fibres

Collagen fibres have different functions depending on their location in the body:

Place of occurrence	Functions of collagen fibres
The skin	Provide structural support and contribute to skin elasticity, enables wound healingand
Joints	Play a key role in maintaining joint structure and function - they provide flexibility and influence joint stabilityand
Muscles	They are responsible for maintaining the integrity and function of movement and play a role in muscle development and regenerationand
Tendons	Provide tensile strength and contribute to the mechanical properties of the tissueand
Arteries and blood vessels	Helps maintain the shape of the vesselsand
Internal organs	Responsible for maintaining the structure of the organs; in the heart, it additionally prevents it from overstretching during contractionand
Hair and nails	In the hair shaft, they provide strength and flexibility and protect against mechanical damage; in the nails, they are responsible for the strength and flexibility of the plate; they are also an important part of the connective tissue that surrounds the nail and provides stabilityand

Magister of Pharmacy Ilona Krzak points out that excess collagen can be detrimental to our health:

Collagen is also involved in the formation of scars. Its excessive and abnormal deposition manifests itself in the formation of scars (keloids). This is primarily an aesthetic problem. Unfortunately, scarring does not disappear on its own, surgery is required.

Scarring is very important.

It is very important to take care of the correct healing of the wound (correct choice of dressing, good wound environment, watching out for the "scab" so that it is not torn off too early.

Also, micro-injuries to the heart can be 'repaired' by excessive amounts of collagen, which causes fibrosis of the organ and impairs its function, leading to, among other things, myocardial infarctions.

Where are the collagen fibres located?

Collagen fibres are found throughout the body. They are like a scaffolding for tissues. They allow them to maintain their shape, elasticity, strength and their motor function. That's why you'll find them practically all over the body - even in the cornea of the eye. Where are they most abundant?

Dermis

The dermis is the inner layer of the skin that lies just below our epidermis. Collagen fibres are arranged in it in a way that resembles a not-so-dense network. They make up about 70-80% of the dry weight of the dermis and are responsible for its structure.

Collagen fibres influence the skin's regeneration processes, taking part in wound healing and scar formation. They also influence its appearance and condition. The collagen scaffolding holds the tissues in place, providing firmness to the skin. This is why, when the production of collagen decreases with age, the skin loses elasticity and wrinkles formand

Periosteum

The periodontium is the tissue that connects your tooth to your gums and is 70-80% made up of collagen fibresand. They prevent teeth from wobbling and falling out. Collagen fibres also play an important role in the structures of the tooth, including the tooth pulp, its cementum and the alveolar bone.

Joints

Collagen makes up approximately 60% of articular cartilage and is present mainly in the connective tissue and in the form of stiff, glassy fibres surrounding joints. Here, collagen fibres form dense structures and provide the joints with the right level of hydration, as well as the right amount of surface glide with movementand

Connective tissue

Connective tissue is one of the tissues that make up our body. As its name suggests connective tissue ... connects other tissues together. Collagen fibres make up about 30% of the dry weight of connective tissue and are responsible for its structure and elasticity.

Collagen fibres ensure its structural integrity and protect it from mechanical damage. In addition, collagen influences tissue regeneration processes, appearance and conditionand

Bones

Collagen fibres make up around 90% of the organic matrix of bone. It is where calcium is deposited. Collagen fibres combine with calcium phosphate crystals to create a durable and strong bone structure and prevent fracturesand

Collagen affects bone structure, so supplementation is often recommended for fractures.

Ilona Krzak Master of Pharmacy

Muscle

Collagen makes up approximately 1-10% of muscle mass and is mainly present in the connective tissue that surrounds muscle fibres. Collagen fibres provide muscles with strength and elasticity. In addition, collagen influences the regeneration processes and the maintenance of muscle strengthand

What produces collagen fibres?

Collagen fibres are produced by different cells in your body, depending on where they are found. Most collagen is produced by fibroblasts, which are cells in the connective tissue. These are responsible for the collagen fibres in the skin.

In the joints, the production of collagen fibres is handled by chondroblasts, or cartilage-forming cells, and in our mouth by odontoblasts, which produce dentinand

How to rebuild collagen fibres?

Until the age of 25, your body produces enough collagen that its fibres regenerate themselves. However, after that, its production declines, which is primarily reflected in the appearance of our skin.

Interesting fact

After the age of 25, your body loses around 1-1.5% of collagen per yearand

To take care of the rebuilding and further production of collagen fibres, you can enrich your diet with collagen-rich products such as gelatine jellies, cartilage, the famous crow's feet or pork knuckles.

See also:

However, collagen contained in food is not absorbed into the body very efficiently because its molecules are large and get trapped on the intestinal wallsand. In addition to this, products rich in collagen are not among the healthiest and should not form the basis of your diet (sorry pork knuckle lovers). So what can you do?

If you want to help your body rebuild collagen fibres, collagen supplementation, preferably in the form of fish-derived hydrolysate, will be effective. Here are some products that will effectively supplement collagen deficiencies

Collagen, elastin and reticulin fibres...

When searching for information on collagen fibres you will also come across elastin fibres and reticulin fibres. What do these terms mean and how do they relate to collagen?

Reticulin fibres, also known as reticular fibres (yes, bingo!, they resemble a fine meshwork in appearance) are made up of collagen fibres and glycoproteins, another type of proteinand

Elastin fibres are also protein chains, but contain other amino acids. They are mainly found in connective tissue, ligaments, tendons, lungs and blood vesselsand

Collagen and elastin fibres are the building blocks of the dermis, forming a loose network in the skin. Collagen fibres are responsible for its structure, providing firmness and an appropriate degree of tension. The elastin gives the skin its elasticity and suppleness. It is thanks to it that the skin can stretch when we gain weight or increase muscle mass.

What destroys collagen fibres?

In addition to the natural loss of collagen that occurs with age, collagen fibres can also be adversely affected byand:

smoking,
excessive alcohol consumption,
deficiencies in copper and vitamins (especially vitamin A, C and E),
long exposure to the sun,
chronic stress,
free radicals,

To avoid destruction of collagen fibres, limit stimulants, ensure a balanced diet and use sunscreen creams

Summary

Collagen fibrils are the extracellular part of tissue, composed of collagen proteins.
Collagen fibrils are the extracellular part of tissue, composed of collagen proteins.
Collagen fibres are found throughout the body - from the eyes to the muscles and bones. They form the structures that give shape to tissues and internal organs.
Collagen fibres are found throughout the body.
Most collagen fibres are produced by fibroblasts, the cells of the connective tissue dermis.
Drugs, vitamin and mineral deficiencies, prolonged sun exposure and stress accelerate the destruction of collagen fibres in the body.

FAQ

How much collagen do we lose after the age of 40?

After the age of 40, your body can lose up to over 20% collagen. This is because its natural production declines after the age of 25. One of the most visible effects of collagen loss is wrinkles. To prevent them and reduce the appearance of those that have already formed, it is worth taking a good collagen supplement, such as Natu.Care Collagen Premium

Can you regenerate collagen fibres?

Yes, you can support the regeneration of collagen fibres in your body by consuming foods rich in vitamin C. It supports the natural synthesis of collagen in the body. Collagen supplementation is also a good way to rebuild collagen fibres.

How to stimulate collagen fibre production

You can stimulate the production of collagen fibres by supplying the body with adequate amounts of vitamin C, which is involved in the collagen production process. To support the natural synthesis of this protein, ensure a balanced diet, rich in copper-containing foods, vitamin A and vitamin E. Research indicates that collagen production is also positively affected by physical activity. You may also find collagen supplements helpful.

When do collagen fibres atrophy?

Collagen fibres start to atrophy after the age of 25 and this is a natural process. After this time, the production of collagen in the body decreases and it is estimated that we lose 1-1.5% of collagen each year.

How much collagen to take per day?

Research indicates that the optimal dose that provides fast and visible results is to take between 2.5 and 15 grams of collagen. Remember not to exceed this daily intake. Excess collagen in the body is not beneficial to health.

What does collagen do?

The effects of collagen you can notice mainly in the condition of your skin. Collagen makes it smooth and tight. Collagen prevents the formation of wrinkles and can contribute to shallowing those that have already appeared. In addition collagen supports your joints and cartilage, ensuring you have smooth movement.

Where are collagen fibres found?

Collagen fibres are found throughout the body. You will find most of them in the skin, connective tissue, joints, bones, blood vessel and intestinal walls and muscles. However, that's not all, collagen is also found in teeth, gums and even in your eyes.
