Why it matters

Marine collagen or bovine collagen?

Fish collagen provides type I – an alternative for anyone who doesn’t want beef.

I like it very much, taste very neutral, even though it is marine.

What to expect

A collagen protocol takes time.The research took time. So does building a routine.

Collagen peptide studies run for weeks or months. That is why a protocol needs one thing above all: consistency.

Clinical studies How long the studies ran

weeks

Studied over weeks

In a clinical study, 76 women aged 50 to 70 took 5 g of this peptide type daily for 8 weeks.

Studied over months

Randomised and placebo-controlled: the fish collagen study ran for 12 weeks – 8 weeks of intake, 4 weeks of follow-up.

How our collagen peptides are made

From collagen to bioactive peptides.

Fish collagen is split by enzymes into short, easily soluble peptides. The result: specific bioactive type I collagen peptides with a defined peptide profile – examined in a clinical study.
Step 1The raw material.

Fish collagen is the starting point.

Step 2Split by enzymes.

Enzymes break the long collagen chains down into short, easily soluble peptides.

Step 3A defined peptide profile.

Specific bioactive collagen peptides, type I – examined in a clinical study.

How we check reviews

We collect reviews through the Judge.me service. Reviews marked “Verified” could be matched to an order in our shop. For reviews without this mark, we cannot check whether the person bought or used the product. We show positive and negative reviews and do not change their text. Reviews of different pack sizes of the same product appear together. English and French versions are translated automatically; you can show the original on each review.

    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 collagen from fish. It consists almost entirely of type I collagen.

In our products 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.

Marine collagen or bovine collagen?

The two differ in their source – fish or beef.

Marine collagen is obtained from fish and consists almost entirely of type I. Our bovine collagen is type I as well.

Which one suits you is mainly a question of preference: anyone who would rather not consume beef chooses fish – unless they have a fish allergy.

How do I take the collagen?

Powder:
Stir the stated daily amount into a drink. The powder is unflavoured and soluble, so it fits easily into your daily routine.

Capsules:
Take the recommended daily amount with enough liquid.

What can I expect from the protocol?

A fixed daily serving, a clearly defined period and bioactive collagen peptides that have been studied in clinical trials. You can read how these studies were designed in the original sources.

Why do you show studies instead of promises?

Because the decision should be yours. We disclose what was studied – with study design, number of participants and original source. We leave the judgement to you.

Why is the protocol designed for 90 days?

Clinical studies on collagen peptides examine intake over several weeks to several months. 90 days is a clearly defined period within this range.

Our collagen protocols are based on the intake periods examined in clinical studies and combine them with a defined daily serving.

The duration is therefore a fixed part of the protocol – alongside the right product and the defined daily serving.

Why bioactive peptides — and not just collagen?

“Collagen” alone does not tell you which specific peptides a product contains. Enzymatic hydrolysis splits collagen into smaller collagen peptides, producing peptides with different properties.

For our protocols we deliberately select specific bioactive collagen peptides, taking into account the peptides, doses and intake periods that have been studied.

This is how we link the choice of peptides to clinical studies – matched to each goal.

Taken every day, with your goal in mind.
