Best marine collagen: my opinion
#1: Marine Collagen Nutri&Co: the best in powder form
Rating: 4.4/5
Nutrition: ★★★★☆
Safety: ★★★★★
Pleasure: ★★★★☆
Brand: ★★★★★
Pack: ★★★★☆
Advantages
- Two types of marine collagen
- Contains vitamin C
- Reliable manufacturing patents
- Subtle but pleasant peach flavor that lets you take it with just water
- Brand reputation
Disadvantages
- Price a bit higher than average
Nutri&co is a French brand created in 2017 and based in Aix-en-Provence. The company, founded by Édouard Fornas, has gained a solid foothold in the nutraceuticals market in recent years.
This powder form is made of marine collagen sourced from controlled fisheries. Several flavors are offered : peach, cucumber-mint, and cocoa.
The daily dose recommended by the brand contains 5.5 g of patented collagen in two types : 5 g of type I (HMG®) and 500 mg of type II (Cartidyss®). These collagens are low molecular weight and considered high quality. It also provides 24 mg of vitamin C per dose.
The powder dissolves easily, and the subtle peach flavor of the tested product is pleasant, without a fishy aftertaste.
The price of €24.90 for a one-month course puts it in the middle of the selection.
#2: Novoma Marine Collagen: the best in capsules
Rating: 4.0/5
Nutrition: ★★★☆☆
Safety: ★★★★★
Pleasure: NA (gélules)
Brand: ★★★★☆
Pack: ★★★★☆
Advantages
- Multiple vitamins plus hyaluronic acid
- Reasonable cost
- Recycled and recyclable bottle
Disadvantages
- Low collagen dosage (specific to the capsule version)
Novoma is a French brand founded in 2012. It offers a wide range of dietary supplements.
The tested marine collagen comes in capsule form with a recommended dose of 3 capsules per day, that is 1 g of collagen. It is composed of two types of low-molecular-weight collagen (I and III), Naticol®-patented, extracted from wild-caught fish and carrying a sustainable fishing label.
Designed for beauty benefits, the capsules are enriched with a blend of vitamins, zinc, and hyaluronic acid (100 mg per 3 capsules).
One month of treatment costs less than €20, a reasonable price compared to other brands. An environmental bonus: the bottle is made from recycled and recyclable plastic.
For a more concentrated collagen version (but paired only with vitamin C), Novoma offers a marine collagen powder recommended at a dose of 10 g per day.
#3: Valebio Joint Marine Collagen: the best for joints
Rating: 4.0/5
Nutrition: ★★★★☆
Safety: ★★★★☆
Pleasure: ★★★★☆
Brand: ★★★★☆
Packaging: ★★★★☆
Advantages
- Very comprehensive for joint support
- 3 types of collagen
- Laboratory that emphasizes transparency
- Naticol® collagen of recognized quality
Disadvantages
- High cost (even though the presence of the other ingredients may justify this price)
Founded in 2015, Valebio is a French nutraceutical brand. The brand emphasizes quality, expertise, and respect for the environment.
The tested marine collagen formula is intended for joint health and includes other active substances: vitamin C, MSM (methylsulfonylmethane), GAGs (glycosaminoglycans), horsetail, and nettle. Their combined properties have a regenerative and anti-inflammatory effect on the joints.
It includes the three types of collagen most common in the human body: I, II, and III. The manufacturer is Naticol®, which has a good reputation. The marine collagen peptides come from a gentle hydrolysis process.
I notice that the mixture clumps and that you need to mix it well for the clumps to disappear. The tangy taste is fairly subtle and pleasant, but I still notice a slight fishy aftertaste at the end.
A one-month course comes to €67.35, which is a notable expense.
Note that Valebio offers other marine collagen formulas with different indications (anti-aging and Absolute).
#4: Twenty DC Magnificent Skin Collagen: the best for skin
Rating: 3.8/5
Nutrition : ★★★★☆
Safety : ★★★★☆
Pleasure : ★★★★☆
Brand : ★★★☆☆
Packaging : ★★★★☆
Avantages
- Well dosed with collagen
- Use of 2 forms of collagen: marine and eggshell membrane
- Nice packaging
Inconvénients
- Flavors with additives: not recommended
- Lack of information on the precise origin of the marine collagen. The collagen manufacturer is not mentioned.
- A bit expensive
Twenty DC is a recent brand (2021) specifically focused on collagen. The tested version targets skin beauty.
This neutral formula consists only of two active ingredients: marine collagen and a small amount of collagen extracted from eggshell membrane (Ovoderm®).
In the absence of clear information on the website and on the product label, I reached out to customer service. I was told that Twenty DC selects manufacturers producing high-quality marine collagen that is subjected to thorough testing.
There are also two flavored versions (peach tea and tropical), but I find these formulas contain too many additives and sweeteners.
The brand recommends taking 10 g of collagen per day (98.5% of the serving is marine collagen). The smell in the tub is not very pleasant. However, the taste is truly neutral. The powder takes a little time to fully dissolve.
A one-month course costs €52.9, which is quite expensive.

Selection criteria
1. Nutritional value
The type of collagen
Type I, II, and III collagen correspond to the main forms found in the tissues of the human body.
Our entire selection contains at least type I collagen, which is abundant in fish skin6.
Some supplements also contain a portion of type II collagen, mainly derived from cartilage and bones, or type III, which also comes from skin.
Molecular weight and bioavailability
For collagen to be properly used by the body, it must be ingested in a fragmented form. To achieve this, the process that cuts it into small pieces is called hydrolysis. This results in a format called collagen peptides, characterized by their size in daltons (or molecular weight). In summary, the lower the molecular weight, the better these peptides are absorbed.
Brevet du fabricant
The hydrolysis method must be sufficiently gentle and free of harmful solvents to preserve all the qualities of collagen peptides. Manufacturers specializing in marine collagen extraction must ensure the process is protected by a patent. Several quality labels are known, such as Naticol®, Collyss®, Cartidyss®, and Verisol®.
Autres substances actives
The formula of the selected collagens is combined with other complementary substances. I have noted their presence and their nature.
2. Safety
Regarding the safety of the different marine collagens tested, I considered:
Fish source
It is important to make sure of the source of the raw material (the fish) from which the collagen is extracted.
Some brands do not always disclose it. I contacted the customer service teams of several of them to get clarification, as the information was sometimes unclear.
The presence of additives and sweeteners
I analyzed the ingredient list of each product to note the presence of additives that can compromise a product’s quality. This is the case, for example, with anti-caking agents (magnesium stearate, silicon dioxide), colorants, or certain artificial flavors. This is an important aspect to consider.
3. Enjoyment
Of the 10 marine collagens in the selection, 8 come in powder form and 2 in capsules. Only the powders were tested, as the capsule version doesn’t impart any particular flavor.
Solubilité
To test the powdered collagens, I mixed the dose recommended by the brand into 200 ml of cold water. I observed the quality and speed of dissolution to achieve a uniform mixture and noted whether or not any lumps were present.
Goût
I evaluated the product’s texture during tasting, the smell it gave off, and the possible presence of a fishy taste.
4. Brand reputation
To assess the brand’s reputation, I took into account the company’s longevity as well as the size of its Instagram following.
Additionally, I looked at customer feedback on Amazon (when the products were available on that platform) and on review sites such as Trustpilot or Avis Vérifiés.
5. Packaging
I assessed the practicality of handling powdered collagen products, considering aspects such as the closure of the tub or sachet, as well as the presence or absence of a measuring scoop.
I also took into consideration the design of the container and the display of information on the label.
Frequently asked questions (FAQ)
Quel est le meilleur collagène : marin ou bovin ?
L’émergence d’études plus récentes sur le collagène marin tendent à montrer qu’il possède des qualités biologiques très favorables5.
De plus, l’extraction du collagène marin permet d’exploiter et de valoriser les sous-produits de l’industrie de transformation du poisson voués à la perte. Par ailleurs, le collagène marin présente des avantages par rapport au collagène bovin : moins de risque de transmission de maladie et aucune considération religieuse6.
Néanmoins, les équipes de recherche ne sont pas unanimes sur l’efficacité de l’un par rapport à l’autre. Ce d’autant que plusieurs facteurs peuvent affecter la manière dont le collagène est assimilé.
Combien de temps dure une cure de collagène marin ?
On retrouve assez peu d’études utilisant exclusivement du collagène marin sur l’homme. Les effets sont plutôt mis en évidence chez l’animal. Il est donc difficile d’apporter une réponse spécifique concernant ce type de collagène.
La revue de la littérature scientifique regroupe plutôt des études sur la prise de peptides de collagène de plusieurs origines. Dans ce cas, la durée moyenne est de 8 à 24 semaines en fonction du sujet étudié (peau7, articulations4…).
Étant donné la baisse progressive de production de collagène avec l’âge6, il semble pertinent d’envisager des cures régulières à partir de 25-30 ans. Cependant, il n’existe pas de recommandations officielles à l’heure actuelle.
Où trouver du collagène marin dans son alimentation ?
Les organismes marins contiennent des substances bioactives de plus en plus utilisées dans le secteur de la santé et de la cosmétique5.
La peau et les arêtes des poissons8 sont plus riches en collagène que la chair. Les sardines, dont on consomme plusieurs parties, sont une excellente source de collagène.
À noter que les calmars, les méduses, les éponges et autres invertébrés sont également des sources abondantes de collagène. Des études récentes ciblent les uns et les autres pour déterminer les caractéristiques de leur collagène.
Où acheter du collagène marin ?
De nombreuses marques de compléments alimentaires proposent du collagène marin.
La grande majorité des marques sélectionnées sont réputées de qualité. L’idéal est de commander directement sur le site de la marque. Plus elle fournit de détails sur son produit, plus c’est un gage de fiabilité : l’origine de la matière première, les conditions d’extraction (brevet du fabricant), la concentration de collagène par dose.
Certaines marques sont par ailleurs distribuées en pharmacies et parapharmacies. Même si la majorité des sites de pharmacies en ligne sont sérieux et fiables, il existe malheureusement quelques exceptions.
Le collagène marin présente-t-il un danger ou des effets secondaires ?
Les nombreuses études menées impliquant une prise de collagène marin ne mettent pas en évidence de danger évident. Les cures de collagène sont, la plupart du temps, sûres et bien tolérées.
Cependant, de rares effets secondaires digestifs ont déjà été rapportés : ballonnements, nausées ou crampes intestinales. Les personnes allergiques au poisson doivent éviter la prise de collagène marin.
De même, le risque de surdosage est très faible car l’excès de collagène est facilement éliminé. Néanmoins, il est toujours recommandé de respecter les doses indiquées.
Quel est le gout du collagène marin ?
Le défi pour les marques qui produisent ce collagène tient plutôt au fait de minimiser le goût de poisson jugé peu agréable par la plupart des consommateurs. Les avis des consommateurs sont un bon indice à ce sujet.
Les versions aromatisées des poudres de collagène peuvent masquer le goût, mais dans ce cas, bien vérifier la nature des additifs présents.
