Why fish collagen?

Type 1 collagen — the key to skin elasticity

Fish collagen consists of type 1 collagen — the most important structural protein of the skin. It accounts for about 80% of the skin’s dry weight and is responsible for firmness, elasticity and hydration. From the age of 25, the body’s own collagen production declines — visible in fine lines, wrinkles and sagging skin.

The marine alternative

Fish collagen is a natural alternative to bovine or porcine collagen. It is particularly suitable for people who do not eat beef or pork for personal, religious or dietary reasons. Fish collagen is neutral in taste, well tolerated and easily absorbed by the body.

High bioavailability

Marine peptides are particularly small — they are absorbed quickly by the body and travel through the bloodstream directly to the fibroblasts. There they send a signal: the prompt to build new collagen and elastin. The result: the skin structure is renewed from within.

The science behind Marine Collagen

Bioactive peptides vs. ordinary collagen

Not all collagen products are the same. Our marine peptides are produced by carefully controlled enzymatic hydrolysis — the fish collagen is broken down into particularly small, specific fragments. These small peptides are absorbed by the body and travel directly to the cells — where they do not just act as building material — they send signals. That signal is exactly what our peptides are made for.

How the signal arises

Once absorbed, the marine peptides travel through the bloodstream to the fibroblasts — the cells that build the structure of the skin. There they act in two ways: they supply amino acids as building blocks, and they stimulate the cells directly to build new collagen and elastin. The result: the body’s own collagen metabolism in the skin is stimulated — from within.

Fibroblasts — the cells that matter

Fibroblasts are specialised cells in the dermis — the deep layer of the skin. Their job: to build and maintain the extracellular matrix of the skin — made up of collagen, elastin and hyaluronic acid. They determine how firm, elastic and hydrated your skin is. When fibroblasts receive the right signal, they actively build new tissue — that is the heart of our protocol.

The extracellular matrix (ECM)

The ECM of the skin is the network of proteins and molecules that surrounds and supports cells — made up of collagen, elastin and proteoglycans. It determines the firmness, elasticity and moisture content of the skin. Marine peptides support the ECM by telling fibroblasts to renew it — the signal comes from outside, the effect happens inside.

Why Marine Collagen from Kollagen Institut?

Clinically studied

Our marine peptides have been tested in peer-reviewed studies — not with a similar product, but with exactly the raw material we use.

In clinical studies, participants showed +7.6% more skin elasticity after 8 weeks, −15% fewer eye wrinkles after 8 weeks and −10% fewer wrinkles still 4 weeks after intake ended (Nutrafoods 2020, n=76).

For the skin — from a marine source

Marine peptides are obtained from fish and are particularly suitable for people who do not eat beef or pork. Our Marine Collagen is derived exclusively from fish — neutral in taste, easily tolerated and with no bovine or porcine ingredients.

Quality from Germany

Our Marine Collagen is manufactured exclusively in Germany and laboratory-tested for purity. The raw material is produced to strict quality standards and certified food-safe.

We deliberately leave out additives, colourings, preservatives and sweeteners — for a pure product with no unnecessary ingredients. And we stand behind our product: with a 30-day money-back guarantee.

Why the right peptides matter

More collagen is not the goal.
What the body does with it is.

When you take ordinary collagen, it is broken down during digestion — like any other protein. It never reaches the places where it is meant to work.

Our marine peptides are smaller and more specific:
they are absorbed by the body and travel through the
bloodstream directly to the fibroblasts — the cells
that build skin elasticity from within. There they send
a signal: the prompt to build new collagen and elastin.
Not supply. Activation.

The body already knows how to renew itself.
The question is whether it gets the right signal.

Your questions. Our answers.

What is collagen?

Collagen is the most abundant structural protein in the human body — responsible for the firmness of skin, tendons and bones. From the age of 25, the body’s own collagen production declines — visible in fine lines, wrinkles and declining skin elasticity.

Why supplement collagen?

As we age, the body’s own collagen production declines. From the age of 25, the amount of collagen in the skin falls by almost 2% a year. By the age of 60 most people have considerably less collagen in their skin than at 25 — noticeable in elasticity, firmness and hydration.

Why Marine Collagen?

Marine peptides are obtained from fish and consist of type 1 collagen — the most important structural protein of the skin. They are particularly suitable for people who do not eat beef or pork for personal, religious or dietary reasons. Bioactive marine peptides send signals to the fibroblasts — the cells that build skin elasticity from within. Not supply. Activation.

Why collagen from Kollagen Institut?

Our peptides are the same ones used in peer-reviewed studies — not similar, but identical raw materials. Clinically studied, produced in Germany, with no additives or preservatives. And with a 30-day money-back guarantee.

How do I take the Marine Collagen?

As a powder: stir one scoop (5 g) daily into water, juice or a drink of your choice — neutral in taste, no preparation. As capsules: 4 capsules daily with a glass of water. Both formats contain 30 servings — one month of the protocol.
