What if the marine collagen you choose matters just as much as taking collagen in the first place?
Marine collagen is collagen obtained from fish, commonly from fish skin. It is processed into hydrolysed collagen peptides, which are smaller peptides that can be digested and absorbed by the body.
For people interested in skin, beauty and healthy ageing, marine collagen has become increasingly popular. But "marine collagen" describes a category, not a single ingredient. The source of the collagen, the fish species and the specific collagen ingredient all matter.
What does marine collagen do?
Collagen is a major structural protein in the skin, contributing to its strength, firmness and elasticity.
Research has investigated whether consuming collagen peptides can support aspects of skin health, particularly skin hydration and the structure of collagen within the dermis.
One of the important ingredients investigated in this area is Peptan®, a specific range of collagen peptides manufactured by Rousselot.
What does the research show?
Clinical research on Peptan® F, a fish-derived collagen peptide, provides useful evidence for skin health.
In a randomised, placebo-controlled study, women taking 10 g of Peptan® F daily for eight weeks experienced a 12% increase in skin moisture. A second clinical study found that 10 g daily was associated with an approximately 9% increase in dermal collagen density after 12 weeks, together with reduced fragmentation of the collagen network.
These studies measured changes within the skin, rather than relying only on participants' perceptions of their appearance.

Why does the specific collagen ingredient matter?
"Marine collagen" doesn't tell you exactly what you're getting.
Different marine collagen products can come from different fish species and manufacturers, use different production processes and have different peptide characteristics. Research conducted on one collagen ingredient should therefore not automatically be applied to every marine collagen product.
The evidence belongs to the collagen ingredient that was studied.
That's why CollagenX identifies its collagen by name.
Pure Wild-Caught Marine Collagen contains 100% Peptan® Marine Collagen Peptides.
What should you look for in a marine collagen?
1. A clearly identified collagen ingredient
Look beyond "marine collagen". Find out which specific collagen ingredient the product contains.
CollagenX uses 100% Peptan® Marine Collagen Peptides, so you know exactly what you're buying.
2. Published human research
Look for clinical research involving the specific collagen ingredient, rather than relying on general statements that collagen has been studied.
Peptan® has been investigated in human clinical research, including studies of skin moisture and dermal collagen.
3. Hydrolysed collagen peptides
Hydrolysis breaks collagen down into smaller peptides that can be digested and absorbed.
CollagenX Pure Wild-Caught Marine Collagen contains 100% hydrolysed Peptan® Marine Collagen Peptides.
4. Know the source and species
Marine collagen can come from different species of fish, and the collagen used in research isn't necessarily interchangeable with collagen from another species or manufacturer.
CollagenX Pure Wild-Caught Marine Collagen is produced from the skins of wild-caught ocean whitefish supplied through MSC-certified fisheries.
So you know both where the collagen comes from and which specific collagen ingredient you're consuming.
5. A simple ingredient list
If collagen is the reason you're buying the product, you should be able to see exactly what else is in it.
CollagenX Pure Wild-Caught Marine Collagen contains one ingredient only: 100% Peptan® Marine Collagen Peptides.
No fillers, gums, artificial colours, flavours or sweeteners.
6. A meaningful daily dose
Look at how much collagen you actually receive per serve. Clinical research investigates specific doses, not simply the presence of collagen.
CollagenX provides 10 g of Peptan® Marine Collagen Peptides per daily serve, matching the daily amount used in the key Peptan® fish collagen studies above.
Why CollagenX chose Peptan®
There are many marine collagen products available. The important question isn't simply whether a product contains marine collagen.
It's which collagen it contains and what evidence exists for that specific ingredient.
CollagenX chose Peptan® Marine Collagen Peptides because the ingredient has published human research behind it.
Our Pure Wild-Caught Marine Collagen combines that researched collagen ingredient with wild-caught ocean whitefish from MSC-certified fisheries and a one-ingredient formulation.
Know your collagen. Know your source. Know the evidence.
