The Marine Collagen Peptides Powder is the only non-bovine option in the Dose & Co range. If you follow a pescatarian diet, prefer marine-sourced supplements, or simply want Type I and Type III collagen from fish rather than cattle, this is your only Dose & Co option.
What is in the Formula?
Each serving delivers 20g of hydrolysed marine collagen peptides alongside 12g of protein, plus added hyaluronic acid and vitamin C. The collagen is sourced from fish and provides Type I and Type III peptides, the same types found in human skin, hair and nails.
Unlike the Pure Collagen (Peptiplus) and Beauty Collagen (VERISOL), the Marine Collagen does not use a named branded peptide ingredient. This does not necessarily mean it is lower quality, but it does mean there is less product-specific clinical data to point to compared to the VERISOL and Peptiplus products in the range.
The addition of hyaluronic acid and vitamin C mirrors the Beauty Collagen formula. Vitamin C is essential for your body to synthesise new collagen, and hyaluronic acid supports skin hydration. The formula is unflavoured, dairy-free, soy-free, gluten-free and non-GMO. It does, obviously, contain fish.
Marine vs Bovine: Which is Better?
This is one of the most common questions in the collagen supplement space, and we have covered it in detail in our bovine vs marine collagen guide. The short version: both are effective sources of hydrolysed collagen peptides. Marine collagen is exclusively Type I (the primary collagen in skin), while bovine provides both Type I and Type III.
Some research suggests that marine collagen peptides may have a slightly lower molecular weight than bovine equivalents, which could theoretically improve absorption. However, the clinical evidence showing a meaningful difference in real-world outcomes is limited. For most people, the choice between marine and bovine comes down to dietary preference, sourcing ethics, and budget rather than a clear superiority of one over the other.
The Value Question
At £32.99 for 221g, this is the most expensive product in the entire Dose & Co range. You get roughly 10 servings per tub at the recommended dose, which means a tub lasts about 10 days with daily use. That works out to approximately £3.30 per serving.
Marine collagen is inherently more expensive than bovine across the entire supplement market, so the premium is not unique to Dose & Co. But it does mean you are paying significantly more per serving than the Pure Collagen (£1.97) or the Vanilla Creamer (£2.08) for the same 20g collagen dose. If you do not have a specific reason to choose marine over bovine, the bovine options in the range represent substantially better value.
What the Amazon Reviews Say
With 115 reviews and a 4.5-star rating, the Marine Collagen has fewer but slightly higher-rated reviews than the bovine powders. Reviewers consistently praise the lack of any fishy taste or smell, which is a genuine concern with marine collagen products. Several reviewers specifically mention choosing this product because they do not eat red meat, and the pescatarian-friendly positioning clearly resonates.
The primary complaint is, predictably, the price. Multiple reviewers note that the tub feels small relative to the cost, and some have switched to the bovine Pure Collagen for better value after trying the marine version.
Who Should Buy This?
The Marine Collagen makes sense if you are pescatarian, if you specifically want marine-sourced collagen for personal or ethical reasons, or if you have tried bovine collagen and experienced digestive issues (some people tolerate marine collagen better). It is also a reasonable choice if your sole focus is skin health, since marine collagen is exclusively Type I, the dominant collagen type in human skin.
If you do not have a specific reason to choose marine, the Pure Collagen at £25.61 or the Beauty Collagen at £29.99 deliver the same collagen dose for considerably less money.
The Marine Collagen Peptides delivers 20g of hydrolysed marine collagen per serving at £3.30 per serve. Best for Pescatarians in the Dose & Co range. For a full comparison of every product, see our Dose & Co brand hub.
