This is a fish-based collagen powder. Each scoop holds 10 g of hydrolyzed marine collagen peptides, mostly Type I with a little Type III, and the Amazon page says the fish are wild-caught. The label calls it gluten free and non-GMO.
The tub holds 34 scoops, so it lasts a bit over a month at the one scoop a day the label suggests. For what the Informed Choice list does and does not check, read our collagen testing list guide.
A good fit if you want a collagen that does not come from cows. Want a bigger tub? Codeage Wild-Caught Marine Collagen gives 50 servings of 9 g (see below).

Common questions
How do I take Sports Research Marine Collagen?
The label says adults mix 1 scoop into a favorite drink or meal once a day. It works in coffee and shakes. For a cold drink, stir it into a room temperature liquid first and add ice after, since the powder can clump in the cold.
Is Sports Research Marine Collagen third-party tested?
It is on the Informed Choice list as Marine Collagen. For Informed Choice, testers buy the tubs at retail and check them for substances banned in sport. The label also shows NSF Certified Gluten-free and IGEN Non-GMO tested.
What does one scoop cost?
It was $34.95 on November 12, 2026, which is $1.03 for each 10 g scoop. A tub covers 34 days at a scoop a day.
What kind of fish is it made from?
The label names barramundi and/or red snapper. The Amazon page says wild-caught fish. It is the fish-based version of Sports Research collagen, not the beef one.
