Marine collagen powder: what to look for
Most collagen pages tell you very little. Source is vague, type is unspecified, the amino acid profile is nowhere to be found. This page is an attempt to do the opposite.
Type I only — and why that matters
Collagen is not a single thing. There are at least 28 types, each with a different structural role and a different amino acid composition. Marine collagen from fish skin and scales is predominantly type I — the most abundant type in the human body, and the form found in skin, tendons, ligaments, bone and cornea.
Some products blend collagen types or do not specify at all. This one does not. It is type I, sourced from fish, and nothing else is added to bulk out the profile.
Wild-caught North Atlantic fish, not farmed
The fish used in this powder are wild-caught from the North Atlantic. That distinction matters to a lot of buyers — particularly pescatarians, people avoiding bovine-derived ingredients, and anyone who wants to know where their raw material actually comes from.
Farmed fish are not inherently inferior, but wild-caught is a more specific claim, and we think specificity is worth something. The supply chain is traceable and the source is declared on the label.
The full amino acid profile — published
Very few collagen brands publish a complete amino acid breakdown. The reasons for this are not always flattering: an unpublished profile cannot be scrutinised.
We publish ours in full on the product page. The profile is dominated by glycine, proline and hydroxyproline — the three amino acids that give collagen its distinctive triple-helix structure and that distinguish it from other protein sources. Hydroxyproline in particular is essentially absent from non-collagen proteins, which is why collagen has a different compositional fingerprint from whey or plant protein.

90g protein per 100g
Each 10g serving contains around 9g of protein by weight. Across the full 250g tub, that is 225g of protein from 25 servings.
One note worth making plainly: collagen is an incomplete protein. It is low in tryptophan and does not cover the full range of essential amino acids the way whey or faba bean protein does. If your goal is total daily protein intake, collagen is not the most efficient route. If your goal is specifically collagen peptides — because you are avoiding bovine sources, or because marine type I is what you want — then the protein density here is high and the cost per serving is reasonable.
Neutral taste despite the source
The most common reason people hesitate over marine collagen is the assumption that it will taste of fish. It does not. The hydrolysis process that breaks collagen into peptides removes the compounds responsible for that flavour. The powder is neutral enough to dissolve into water, coffee, juice or a shake without altering the taste of the drink.
Mixing is straightforward — hot or cold liquid, stir until dissolved. No gritty residue, no film on the surface. One 10g scoop into around 250ml of your chosen liquid is all it takes.
£1.16 per serving
The 250g tub contains 25 servings at 10g each. At the current price, that works out to £1.16 per serving — a figure that is easy to compare directly with other collagen powders once you know the serving size and peptide content of what you are comparing it to.
Many products use a 5g serving to make the price per serving look lower. This one uses 10g. Check the serving size before you compare.

Pairs well with vitamin C
If you already take vitamin C — or eat fruit and vegetables regularly — there is nothing extra to do. If you want to take both together, Pump House makes a 500mg vitamin C chew that is easy to take alongside the collagen powder. Add vitamin C — vitamin C contributes to normal collagen formation for the normal function of skin, gums, bones, teeth, cartilage and blood vessels.
Allergen information
Contains fish. This product is derived from fish (skin and scales). It is not suitable for anyone with a fish allergy. If you are allergic to a specific species of fish, check with the manufacturer before use — the raw material declaration is available on request.
Manufactured in a facility that handles other allergens. See the full label for details.
Not sure whether marine or bovine is right for you?
Neither is objectively better. The difference is source, type and who it suits. Bovine or marine? — neither is better. They suit different people.
