Why it matters

Skin structure and elasticity rely on the body’s own collagen.

Collagen is the most abundant structural protein in skin. Marine peptides are hydrolysed collagen — broken down into short chains.

I started using the marine collagen a few months ago and then started noticing improvements in my skin (firmer) and hair (fuller). I then stopped taking the collagen again and unfortunately have to say that my skin and hair seem to have worsened again.

What to expect

Collagen production takes time.Elasticity improves step by step.

When marine collagen peptides activate your fibroblasts, collagen production increases step by step, and visible changes emerge from the inside out.

2-4
weeks

Hydration & fullness

First improvements as your skin holds more moisture and feels visibly plumper.

4-8
weeks

Elasticity & texture

The skin becomes more resilient and smoother as your fibroblasts build new collagen.

8-12
weeks

Firmness & structure

Elasticity and density become visible - the skin looks firmer and finer.

Some customers report early changes

Dissolves well in coffee and tastes of nothing – exactly what I wanted. Obviously too early for visible results.

Changes are increasingly mentioned

My skin looks noticeably fresher in the mornings and feels plumper. It used to be rather dull at this time of year.

    marine collagen

    I take the marine collagen in powder form at a high dose and it dissolves completely and is flavour neutral. It definitely helps me with my ligaments and tendons too. I would like to know more about the bioavailability and where the fish collagen comes from, how sustainable and environmentally friendly it is, whether these values are taken into account, that information is missing for me.

    Well tolerated

    As I have not been using the product long, I cannot review it fully yet. It is well tolerated by me. I put it in my tea. There it is minimally noticeable in the taste.

    Marine Collagen Powder

    I have now been taking the product for about 4–5 months. It dissolves outstandingly in various liquids. The taste is in my opinion neutral. My naturopath gave me the tip of adding a little vitamin C for optimal performance in the body. My beautician noticed a positive change in my skin on the décolletage and face. I will carry on taking it and recommend it.

Questions about marine collagen

Where fish collagen comes from, how it differs from bovine collagen, and how to take it daily.

What is marine collagen?

Marine collagen is a protein obtained from fish — usually from the skin and scales of cod or salmon. It consists almost entirely of type I collagen.

As a supplement it comes in hydrolysed form: the collagen has been broken down enzymatically into smaller peptides. These peptides are rich in glycine, proline and hydroxyproline — the amino acids that make up the bulk of the collagen molecule.

Is marine collagen as good as bovine collagen?

The two differ in source and collagen type, not in quality.

Marine collagen is obtained from fish and consists almost entirely of type I. Bovine collagen supplies types I and III. Type I is the most abundant collagen type in skin and bone; type III occurs there alongside it.

Which one suits you is mainly a question of preference: anyone who would rather not consume beef chooses fish. For people with a fish allergy, marine collagen is not an option.

How do I take the collagen?

Our collagen fits easily and flexibly into your daily routine.

Powder:
Stir the recommended daily amount into water, coffee, tea, or a smoothie. It is tasteless and dissolves well in both cold and warm drinks.

Capsules:
Take the recommended daily dose with plenty of liquid - ideally with a meal.

When will I see results?

The studies on collagen peptides work with periods from eight weeks up to several months of daily intake. Shorter periods are barely studied. How it plays out for you personally depends on age, diet and how regularly you take it.

Why exactly 90 days?

Collagen is continuously built up and broken down in the body. The studies on collagen peptides therefore work with periods of several months — 90 days matches that order of magnitude.

Why bioactive peptides — and not just collagen?

These are bioactive collagen peptides — a specific peptide fraction studied clinically for targeted effects. Generic collagen has an undefined peptide structure and is usually not clinically studied.

Is long-term use safe?

Yes. The peptides used have been studied in long-term trials over several years.

Taken daily. Benefits build over time.
