The short answer
The same collagen, under the same patented label and in the same 500 g size, sells for 39.90 EUR at one brand and 78.95 EUR at another: a 98% gap for an identical ingredient. Over a year-long course at 10 g a day, that is 285 EUR. Collagen is the comparison where the choice of brand weighs the most, and where it is least justified.
The label is the same, the price is not
Peptan® is a marine collagen hydrolysate produced by Rousselot. When two brands display it, they sell the same ingredient, from the same supplier, with the same molecular weight: below 2,000 daltons in both cases. There is nothing to weigh up on quality: what remains is price.
| Product | Label | Size | Price | Price per kilo | Cost at 10 g/day |
|---|---|---|---|---|---|
| Nutripure, wild marine collagen | Naticol® | 4 kg | 249.90 EUR | 62.48 EUR | 0.62 EUR |
| Nutripure, wild marine collagen | Naticol® | 1.2 kg | 89.90 EUR | 74.92 EUR | 0.75 EUR |
| Dynveo, marine collagen powder | Peptan® | 500 g | 39.90 EUR | 79.80 EUR | 0.80 EUR |
| Nutripure, wild marine collagen | Naticol® | 310 g | 33.90 EUR | 109.35 EUR | 1.09 EUR |
| Novoma, marine collagen powder | Naticol® | 284 g | 32.90 EUR | 115.85 EUR | 1.16 EUR |
| Nutrimuscle, marine collagen | Peptan® | 1.2 kg | 159.95 EUR | 133.29 EUR | 1.33 EUR |
| Nutrimuscle, marine collagen | Peptan® | 500 g | 78.95 EUR | 157.90 EUR | 1.58 EUR |
| Nutri&Co, marine collagen | Naticol® + Cartidyss® | 180 g | 30.90 EUR | 171.67 EUR | 1.72 EUR |
| Nutrimuscle, marine collagen | Peptan® | 200 g | 34.95 EUR | 174.75 EUR | 1.75 EUR |
With strictly identical size and label (Peptan®, 500 g), the gap is 98%. It is the biggest gap we have recorded on a supplement, and no documented difference between the products explains it.
Size matters too, as always: at Nutrimuscle, the 1.2 kg pot comes down to 133.29 EUR a kilo against 174.75 EUR for the 200 g one, which is 24% less. But even its best size stays 67% above Dynveo’s price.
Update of 23/10/2026: Nutripure takes the lead. Its Naticol marine collagen, hydrolysed to 2,000 daltons according to its page, costs 74.92 EUR a kilo in the 1.2 kg pot and 62.48 EUR in the 4 kg tub, below Dynveo’s 79.80 EUR. The tub represents more than a year’s course at 10 g a day: for a first purchase, the 1.2 kg pot is the sensible size, and it is still the cheapest in the table. Its 310 g pouch, on the other hand, climbs back to 109.35 EUR a kilo.
Update of 27/10/2026: Novoma added. Its Naticol powder in a 284 g pot, with 150 mg of vitamin C per 10 g serving, works out at 115.85 EUR a kilo, between Nutripure’s 310 g pouch and Nutrimuscle’s 1.2 kg pot.
What dose, and for what
The product pages converge on similar benchmarks, which is reassuring: 5 g a day for a skin goal, 10 g a day for joints. Nutri&Co recommends 6 g. These doses match what the literature usually explores: in the order of 5 to 15 g for skin, and from lower doses for joints.
The consequence for your budget is direct: at 5 g a day, the cheapest product works out at 0.40 EUR a day, or 146 EUR a year. At 10 g and the highest price in the table, it rises to 638 EUR. The same goal, four times the price.
Where a brand can set itself apart
The ingredient list. This is the only real difference in the table. Dynveo states “100% marine collagen powder”, Nutripure a “100% pure” collagen in its neutral version. Nutrimuscle does too in its plain version; its flavoured versions add flavourings, citric acid, concentrated juice and steviol glycosides. Nutri&Co adds acacia gum, flavourings, citric acid and vitamin C, the latter not being a flaw, since vitamin C takes part in collagen synthesis. Novoma does the same, with 150 mg of vitamin C per 10 g serving, and adds a natural flavouring in its four flavoured versions.
The type of collagen. Peptan® and Naticol® are type I, the main type in skin. Nutri&Co combines Cartidyss®, presented as type II, the type found in cartilage. The combination is coherent on paper; its clinical advantage over type I alone is not established in a comparable way.
Fishing certifications. Both Peptan® products highlight MSC certification and French manufacture. The Novoma powder highlights Friend of the Sea certification and French manufacture. It is a legitimate sourcing criterion, with no nutritional effect.
One precaution, only one
Collagen is well tolerated at the usual doses. The documented reservation concerns high doses: the hydroxyproline it provides can increase urinary oxalate, which calls for caution in people prone to kidney stones, above 10 g a day. Outside that case, no notable side effect is reported in healthy people.
A useful reminder: collagen is a protein, and a protein of mediocre quality in terms of essential amino acids. It does not replace the protein intake from your plate: see our whey comparison and our guide to how the body uses protein.
