Everything You Need to Know About Collagen

Collagen has become increasingly popular in recent years. It is often seen as something for firmer skin or fewer wrinkles. But that is actually only a small part of the story. Collagen is not a cosmetic detail. It is literally one of the most important building blocks of your body. It determines how strong, supple, and resilient your tissues are. And that is precisely why it is interesting to understand what it is, how it works, and what changes as you age.

What is collagen?

Collagen is the most abundant protein in the human body, making up about one-third of all the protein your body contains.

It is a so-called structural protein. This means it provides firmness, cohesion, and structure.

You can find collagen in, among other places:

• the skin (elasticity and firmness)
• bones (strength and density)
• tendons and ligaments (tensile strength and flexibility)
• muscles and connective tissue
• blood vessels and organs

Without collagen, these structures would lose their shape and strength. It is no coincidence that the word collagen comes from the Greek word kólla, meaning 'glue'.

How does collagen work in the body?

Collagen has a unique structure. It consists of three long amino acid chains that together form a so-called triple helix. This gives collagen its combination of strength and flexibility.

The main building blocks are:

• glycine
• proline
• hydroxyproline

Glycine forms the core of the structure, while proline and hydroxyproline provide stability. What is often forgotten is that collagen is not simply "present."

It is continuously broken down and rebuilt.

This process occurs through several steps:

1. Supply of building blocks (amino acids from food)
2. Formation of procollagen in cells
3. Hydroxylation (dependent on vitamin C)
4. Assembly into fibers outside the cell
5. Strengthening through cross-linking (with zinc and copper, among others)

This means that collagen production depends on multiple factors simultaneously. Not just proteins, but also vitamins, minerals, and overall health play a role.

What changes with age?

Until approximately age 25, the body produces sufficient collagen. After that, this production gradually decreases. This is a normal biological process.

Over the years, this can manifest as less firm skin, wrinkle formation, stiffer joints, and slower tissue recovery. Important to understand: this is not a sudden process, but a gradual shift. And that shift is influenced by lifestyle.

What often goes wrong?

The decline of collagen is often seen only as a matter of age. But that is too simplistic.

There are multiple factors that can accelerate collagen breakdown or disrupt its synthesis:

• chronic stress (elevated cortisol)
• poor sleep
• nutritional deficiencies (vitamin C, zinc, proteins)
• smoking and alcohol
• high sugar intake (glycation of collagen fibers)
• lack of exercise

The problem often lies not only in reduced production, but also in increased breakdown and less efficient synthesis.

Different types of collagen

There are multiple types of collagen, but three are the most important:

• Type I (±90%) → skin, bones, tendons, and connective tissue
• Type II → cartilage and joints
• Type III → organs, blood vessels, and skin

Type I is by far the most abundant in the body and plays a major role in structure and firmness.

How is collagen absorbed?

When you consume collagen through food or supplements, something important happens. It does not remain intact. In the digestive tract, collagen is largely broken down into individual amino acids and short peptide chains. These are absorbed into the bloodstream and then used as building blocks. Some of these peptides also seem to have a signaling function for cells that produce collagen, such as fibroblasts.

Afterward, the body itself begins to synthesize new collagen.

This means: collagen you ingest → does not directly become collagen in your skin

but → provides building blocks AND signals for production

What can you do to support collagen?

If you understand how collagen works, it also becomes clear where your influence lies.

Not in a single isolated solution, but in the fundamentals.

1. Eat enough protein Collagen is made up of amino acids. Without protein, there are no building blocks.
2. Ensure sufficient vitamin C Essential for the stability of collagen structures.
3. Pay attention to minerals like zinc and copper These support the synthesis and strengthening of collagen fibers. Such as grass-fed red meat, eggs, shellfish, nuts, seeds, and liver.
4. Limit strong blood sugar fluctuations Sugar can damage collagen through glycation. Glycation is a process where sugar molecules bind to proteins like collagen, making them stiffer, less flexible, and more prone to damage.
5. Exercise regularly Mechanical loading stimulates tissue building.
6. Support recovery (sleep and stress) Chronic stress inhibits recovery processes.
7. Foods like bone broth Rich in collagen and gelatin, provides direct building blocks.
8. Collagen as a supplement Can contribute as an additional source of amino acids and peptides. It is important that the collagen is hydrolyzed (broken down into smaller peptides) so that it is more soluble and can be absorbed more efficiently by the body.

The most important thing here is consistency, not perfection.

How and when to take collagen?

Collagen is relatively easy to use. It can be added to coffee, tea, yogurt, smoothies, and also to hot and cold drinks. Timing is less important than regularity. Many people choose morning or evening, but the effect is mainly in daily use.

Why quality matters

Not all collagen sources are the same.

Factors that make a difference include the origin of the animals, the processing method, and the purity of the product. Because collagen is a structural protein, the quality of the source partly determines the quality of what you ingest.

At ELVOU, a conscious choice was made for bovine collagen from grass-fed cows in Argentina. These cattle live outdoors all year round and have access to grass, air, land, and water 365 days a year. They eat fresh grass their entire lives and are fully traceable back to the farmer. In addition, the animals are never given antibiotics, hormones, or steroids.

Processing also plays an important role. The collagen is extracted from the hides of the cattle, after which the gelatin is hydrolyzed. This means that the collagen proteins are molecularly broken down into collagen peptides, so they are more soluble and can be absorbed more efficiently by the body.

Furthermore, type I collagen was chosen, the form that makes up about 90% of the collagen in the human body and is mainly found in skin, bones, tendons, and connective tissue. The product contains no unnecessary fillers or additives and is entirely focused on the purity and quality of the raw material itself.

Ultimately, quality is not just about how much collagen a product contains, but primarily about the question:

Conclusion

Collagen is not a hype, but a fundamental part of your body. It determines the structure of your skin, bones, tendons, and connective tissue. With age, production decreases, but this process is strongly influenced by lifestyle. Supporting collagen is not about one solution, but about the whole: nutrition, recovery, micronutrients, and behavior. When that foundation is in place, the body gets the right conditions to continue building itself.
