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.

Switched from the powder to the capsules because I travel a lot. Far simpler – since then I genuinely take them every day.

  • I was skeptical it would taste fishy like other marine collagen powders. But honestly, I can’t taste anything at all. I think my skin looks much better than before.

  • After nine weeks my hair is doing much better, with much less hair loss. Overall, I’m really happy with the result.

  • The famous menopause is not exactly helpful where the condition of skin and hair is concerned. I looked for natural support — and found it with the Marine Collagen.

    Fast delivery, good product

    The main reason for my order was to support my knee joint a little – and after only a few days I noticed that the complaints were lessening, and lastingly so. The delivery arrived very quickly. Many thanks, happy to order again!

    A good effect on the nails

    I have not been taking the Marine Collagen capsules very long, but I have already noticed a clear improvement in my nails – they have become stronger. With hair and skin I cannot detect any clear change so far. As I am still young and my skin had no problems, that is hard to judge. My hair has not grown faster so far, but I have also only been taking the collagen a short time. All in all the product makes a good impression, so I will keep taking it.

    great

    I have now been taking the fish collagen capsules for a year and I notice an improvement in my skin. Generally I have the feeling that the capsules help me keep my body healthy. I am very satisfied and taking the capsules is also much easier for me than powder.

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 natural protein taken from fish. It is made up of specific collagen peptides rich in amino acids such as glycine, proline and hydroxyproline — the building blocks your body uses for its own collagen structure.

As a supplement, marine collagen is used to support the natural function of skin, joints and connective tissue. Its good bioavailability means the body can absorb and use it efficiently.

Is marine collagen as good as bovine collagen?

Marine collagen is derived from fish and differs from bovine collagen mainly in its finer peptide structures. These are easy to digest and highly bioavailable, allowing the body to absorb them efficiently.

That makes marine collagen particularly well suited to supporting skin from within. It can help promote elasticity and hydration, and support a more refined-looking complexion over time.

Both types of collagen have their strengths - but marine collagen is often preferred for its excellent tolerability and absorption.

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?

Visible changes typically appear after 4–8 weeks of daily use. Lasting effects build over the course of months.

Why exactly 90 days?

Collagen building is a step-by-step process. 90 days give the body enough time for real structural changes — not just surface-level ones.

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.
