Every marine collagen we checked, ranked
We read each tub's Supplement Facts panel, searched five testing lists for it, and priced it per 10 g of collagen. Tested powders come first, then the rest from cheapest to most expensive. All 8 are unflavored and list one ingredient: fish collagen.
| Powder | Fish (label) | Testing list | Per 10 g |
|---|---|---|---|
| Sports Research 10 g a serving, 34 servings | Barramundi and/or red snapper | Informed Choice | $1.03 |
| Codeage 9 g a serving, 50 servings | White fish (cold water) | NSF/ANSI 173 | $1.22 |
| Micro Ingredients 12 g a serving, 37 servings | Whitefish | None found | $0.68 |
| Naked 12 g a serving, 47 servings | Cod | None found | $0.89 |
| Amandean 10 g a serving, 50 servings | Deep sea fish (kind not named) | None found | $0.96 |
| Nutricost 10 g a serving, 23 servings | Pacific cod | None found | $1.08 |
| Orgain 12 g a serving, 20 servings | Alaskan pollock | None found | $1.33 |
| Vital Proteins 12 g a serving, 18 servings | Cod | None found | $1.43 |
- Sports Research ($1.03) is our pick: on a testing list, 10 g a scoop, and the fish is named on the label.
- Codeage ($1.22) is the only one on NSF/ANSI 173. Its scoop is smaller, 9 g.
- Micro Ingredients ($0.68) is the cheapest per gram. We found it on no testing list.
- Vital Proteins ($1.43) costs the most per gram here. On Amazon it is sold by a third-party seller, not Vital Proteins. Its plain bovine collagen is NSF listed; this marine powder is not.
Which marine collagens are third-party tested?
2 of 8. We searched each program's own list on October 5, 2026. A listing counts only if it names this product.
- Informed Choice lists Sports Research Marine Collagen. The program buys products off the shelf and tests them for substances banned in sport.
- NSF/ANSI 173 lists Codeage Wild-Caught Marine Collagen Peptides, at the same 9 g scoop as the tub. That standard checks that the label is accurate and that contaminants stay under set limits.
- NSF Certified for Sport, Informed Sport and USP Verified list none of the 8. A search of NSF Certified for Sport for "marine" returns nothing.
- The other 6 are on none of these lists. Some, like Micro Ingredients, Amandean and Nutricost, say "third-party tested" on the listing. That is the brand's own claim. No public list we can check backs it.
Proof: the two marine collagens on a testing list
Informed Choice: Sports Research
NSF/ANSI 173: Codeage
Testing matters most if you get drug-tested for sport or work. For everyone else, it shows the company lets an outside lab check its product. It does not mean the collagen works better.
What the labels say
Both panels list fish collagen and nothing else. Sports Research gives 10 g a scoop; Codeage gives 9 g.
Fish allergy: every tub here is made from fish, and every label names fish as the source. If you are allergic to fish, skip marine collagen and look at bovine.
Marine vs bovine collagen
On the label, they are close. Marine costs more. Per 10 g, both kinds give about 9 to 10 g of protein. Marine listings that name a type say type I, and some add type III. For more on types, see collagen types compared.
| Kind | Range per 10 g | Middle |
|---|---|---|
| Marine (8 powders) | $0.68 to $1.43 | $1.06 |
| Bovine (3 plain powders) | $0.48 to $0.73 | $0.57 |
Same brand, both kinds: Sports Research's bovine collagen is $0.73 per 10 g; its marine is $1.03. At 10 g a day, marine costs about $8.92 more a month.
Brand pages often say marine collagen absorbs better. That is a marketing claim, not a label fact. Pick marine if you don't eat beef or prefer fish. If price matters most, bovine is cheaper. How much to take: collagen dosage guide.

Questions
What is the best marine collagen?
Sports Research Marine Collagen Peptides. It is on the Informed Choice testing list, which checks for substances banned in sport. Each scoop is 10 g of collagen from fish, with nothing else added. It costs $1.03 per 10 g on Amazon. Codeage is the other tested option (NSF/ANSI 173) at $1.22 per 10 g.
Is any marine collagen third-party tested?
Only 2 of the 8 we checked are on a public testing list. Sports Research Marine Collagen is on Informed Choice. Codeage Wild-Caught Marine Collagen Peptides is on NSF/ANSI 173, which checks that the label is right and contaminants stay under set limits. We found the other 6 on none of five lists: NSF Certified for Sport, NSF/ANSI 173, USP Verified, Informed Sport and Informed Choice. "Third-party tested" on a tub is the brand's own claim.
Is marine collagen better than bovine?
Not on the label. Per 10 g, both give about 9 to 10 g of protein. Marine listings that name a type say type I, and some add type III; bovine is types I and III. Marine costs more: the median marine powder here is $1.06 per 10 g, and the plain bovine powders we track run $0.48 to $0.73. Pick marine if you don't eat beef or prefer fish. Skip it if you are allergic to fish.
What is the best marine collagen for women?
The same as for anyone: Sports Research Marine Collagen. None of these powders has a women's formula; the collagen is the same. Women who want the lowest price can buy Micro Ingredients ($0.68 per 10 g), which is on no testing list.
What is the cheapest marine collagen per gram?
Micro Ingredients, at $0.68 per 10 g of collagen ($29.99 for 37 servings of 12 g). The most expensive here is Vital Proteins, at $1.43 per 10 g. Compare tubs per gram, not per scoop: a scoop is 9 g in one tub and 12 g in another.
What fish is marine collagen made from?
It depends on the brand. The labels we read name cod (Naked, Nutricost, Vital Proteins), Alaskan pollock (Orgain), barramundi or red snapper (Sports Research), and white fish (Codeage, Micro Ingredients). Amandean says only "wild-caught deep sea fish." Every label names fish as the source.
