Hunter and Gather’s Marine Collagen is the fish-sourced alternative to their bestselling bovine powder. If you cannot tolerate beef, prefer not to use cattle-derived products, or specifically want to target skin, hair, and nail health, this is the one designed for you.
But is there a meaningful difference between marine and Hunter & Gather’s bovine collagen, and is this particular product worth the slightly higher price? Here is what we found.
What Is It?
Another single-ingredient product from Hunter and Gather: 100% hydrolysed marine collagen peptides from wild-caught whitefish. No additives, no flavourings, no fillers. The fish are sourced from the North Atlantic, Norwegian, and Barents seas, and the collagen is extracted from the skin of the fish, which would otherwise go to waste from the fishing industry. It delivers Type I collagen only, which is the most abundant collagen type in the human body and the one most directly linked to skin elasticity, hair strength, and nail health.
The key difference from the bovine version is the collagen type profile. Bovine gives you Type I and III. Marine gives you Type I only, but in a form that some research suggests is more bioavailable, meaning it may be absorbed more efficiently by the body. If your primary concern is skin and beauty outcomes rather than broad-spectrum joint and gut support, marine collagen is generally considered the more targeted choice.
Hunter & Gather Marine Collagen
- 10,000mg wild-caught marine collagen per serving (Type I)
- Sourced from North Atlantic, Norwegian, and Barents Sea whitefish
- Single ingredient, unflavoured, no additives
- 300g pouch provides approximately 30 servings
- Every batch independently lab-tested for purity
Sourcing and Quality
The whitefish are sustainably wild-caught, not farmed. Hunter and Gather are clear that they never use farmed fish, shark, shellfish, or tilapia. The sourcing covers the North Atlantic, Norwegian, and Barents seas, which are well-regarded for fish quality. Like their bovine collagen, every batch is independently lab-tested for heavy metals, toxins, and microbes, and no solvents are used in the production process.
It is worth noting that the marine collagen is not MSC-certified (Marine Stewardship Council), which Ancient and Brave’s Wild Collagen does hold. Hunter and Gather describe their sourcing as sustainable but do not carry the formal third-party certification. That may matter to you if independent sustainability verification is a priority, or it may not if you are satisfied with their transparency on sourcing practices.
Nutritional Profile
Each 10g serving (roughly two level tablespoons) provides approximately 9g of protein, with zero fat, zero carbohydrates, and zero sugar. The serving size is smaller than the bovine version (10g versus 13g), which reflects the different concentration and the higher bioavailability often attributed to marine collagen peptides. A 300g pouch gives you roughly 30 servings at the standard dose, so one bag lasts about a month.
The amino acid profile is similar to bovine but with a slightly different emphasis. Marine collagen tends to be richer in glycine and proline relative to its total weight, both of which are key building blocks for skin collagen synthesis. It delivers the same essential amino acids but in a formulation that is considered particularly well-suited to beauty and skin health applications.
Marine Collagen Taste and Mixing
This is where marine collagen can be a sticking point for some people, and Hunter and Gather is no exception. The powder is described as unflavoured and it dissolves well in both hot and cold liquids. In hot coffee or tea, most users report it is virtually undetectable. However, some customers, particularly on Trustpilot, mention a noticeable fish taste or smell that they find harder to mask in milder drinks or plain water.
This is a common characteristic of marine collagen across all brands, not specific to Hunter and Gather. If you know you are sensitive to fish flavours, you may want to stick to mixing it into strongly flavoured drinks or foods. The bovine collagen is generally better tolerated from a taste perspective, so it comes down to whether the skin-specific benefits of marine collagen outweigh any taste compromise for you personally.
If taste matters to you, we’d recommend either Hunter & Gather’s Cocoa Collagen, or their Vanilla Collagen Creamer to add to your morning brew – both offer exceptional nutritional profiles and a genuinely great taste.
Tasty Alternative: Hunter & Gather Collagen Creamer
- 13,000mg grass-fed bovine collagen per serving
- Dairy-free creamer with organic coconut milk and natural vanilla
- No added sugar, sweeteners, or artificial flavourings
- Replaces milk, creamer, and collagen in one scoop
- 300g pouch provides approximately 15 servings
Hunter & Gather Marine Collagen Reviews
The marine collagen gets strong reviews, though the volume of reviews is lower than the bovine powder since it is a newer addition to the range. Customers who specifically chose it for skin, hair, and nail health report positive results, with stronger nails and improved skin hydration being the most frequently mentioned benefits. Several reviewers note visible changes in hair thickness and shine within two to three months.
The taste issue comes up in a minority of reviews. Some customers mention they switched from the marine to the bovine after finding the fish flavour too noticeable for their liking. Others say they cannot taste it at all in hot drinks. Your mileage will genuinely vary on this one. The 60-day money-back guarantee does take the risk out of trying it, which is worth bearing in mind.
What’s nice is that Hunter & Gather personally respond to many reviews on Trustpilot (check out the image above!), both positive and the very rare negative / neutral reviews. It adds a nice touch even though this collagen company is now one of the largest in the UK.

Marine collagen is more expensive than bovine per gram, which is standard across the industry because the raw material costs more. At £0.96 per serving on subscription, it is reasonably priced for a wild-caught, lab-tested marine collagen. For comparison, Ancient and Brave Wild Collagen costs £34 for 200g (40 servings at 5g), working out to £0.85 per 5g serving. If you compare per gram, Hunter and Gather is slightly cheaper. The bundle with bovine collagen is worth considering if you want to combine both types, as it offers a small saving versus buying separately.
How It Compares
Against Ancient and Brave Wild Collagen, Hunter and Gather offers a larger pack (300g versus 200g), a higher recommended serving (10g versus 5g), and competitive per-gram pricing. Ancient and Brave has the advantage of MSC certification and their BECOME Study clinical trial, which showed impressive results for skin hydration and elasticity specifically with their marine collagen. Against Bare Biology Skinful, another popular marine collagen in the UK, Hunter and Gather is similarly priced but with more transparent sourcing information.
Against their own bovine collagen, the marine version is the better choice if skin and beauty are your primary goals. The bovine is better for all-round support including joints, gut, and muscles thanks to the Type III content. Hunter and Gather themselves suggest combining one tablespoon of each for a comprehensive daily dose.
Who Should Buy This?
This product suits anyone specifically targeting skin, hair, and nail health, anyone who avoids beef for dietary or personal reasons, and anyone who prefers fish-sourced supplements. The wild-caught sourcing and lab testing give confidence in quality, and the 300g pouch is generously sized for a marine collagen. It is also a good option for pescatarians who still consume fish products.
Skip it if you are sensitive to fish flavours and worried about taste in lighter drinks, if you want Type III collagen for muscle and organ support (go bovine instead), or if MSC certification is non-negotiable for you (look at Ancient and Brave Wild Collagen). Also obviously not suitable if you have a fish or shellfish allergy.
Our Verdict: 4.4 out of 5
A solid marine collagen that delivers exactly what it promises: pure, wild-caught, single-ingredient Type I collagen in a well-priced format. The sourcing is transparent, the lab testing is thorough, and the customer feedback on skin and hair results is encouraging. It loses a fraction of a point against the bovine version for the taste sensitivity issue and the lack of formal sustainability certification, but neither is a dealbreaker. If marine collagen is what you want, this is one of the best options available in the UK.

Frequently Asked Questions
Is marine collagen better than bovine for skin?
Marine collagen delivers Type I collagen, which is the primary collagen type in human skin. Some research suggests marine collagen peptides may be more bioavailable than bovine. For skin-specific goals, marine is generally considered the more targeted option. Bovine collagen (Type I and III) is better for all-round support.
Does Hunter and Gather marine collagen taste fishy?
In hot drinks most users report no detectable taste. In cold water or mild-flavoured drinks, a minority of customers notice a slight fish taste or smell. This is typical of all marine collagen products, not unique to Hunter and Gather. Mixing into strongly flavoured drinks minimises it.
Can I take marine and bovine collagen together?
Yes. Hunter and Gather recommend combining one tablespoon of each (6.5g bovine and 5g marine) for a daily total of 11.5g that covers Type I and III. They advise staying within their overall guideline of 30 to 40g total collagen per day.
Where is the fish sourced from?
Wild-caught whitefish from the North Atlantic, Norwegian, and Barents seas. No farmed fish, shark, shellfish, or tilapia is used. The collagen is extracted from the fish skin, which would otherwise be waste from the fishing industry.
Is it MSC-certified?
No. Hunter and Gather describe their marine collagen as sustainably sourced from wild-caught fish but it does not carry MSC (Marine Stewardship Council) certification. If formal third-party sustainability certification matters to you, Ancient and Brave Wild Collagen holds MSC certification.
How long does it take to see results?
Most customers notice improvements in skin hydration and nail strength within four to six weeks. Hair thickness and shine tend to improve over two to three months. Consistency matters more than dose, so daily use is recommended.
