About
What it is.
Marine Collagen is a fish-derived collagen supplement from Vital Proteins, part of the brand's broader collagen line alongside its bovine-based products. It's produced from the scales and skin of wild-caught white fish sourced off Alaska, providing type I and type III collagen in a form the body can absorb readily. It's sold as an unflavoured powder meant to dissolve into drinks, with a capsule version offered for those who prefer a fixed dose over mixing.
Formulated for people focused on skin, hair, and nail condition as well as joint support, it fits the sleep-and-recovery supplement category through its role in daily restorative routines rather than active performance. It's positioned for shoppers who want a fish-sourced alternative to bovine collagen, made under US manufacturing standards.

Frequently asked
What buyers want to know.
Has anyone tried marine collagen?r/AskWomenOver40
Buyers report visible results on skin, hair, and nails within a couple of months. Some owners switched from bovine collagen to this marine version and found it noticeably harder to dissolve.
Hydrolyzed Marine collagen or Hydrolyzed Bovine collagen?r/Supplements
Buyers who've tried both say the marine collagen delivers similar visible skin and hair results but dissolves worse than the bovine version. Marine collagen is the pescatarian option if that matters to you.
Best collagen peptide product?r/30PlusSkinCare
This marine collagen ranks among top picks for collagen supplements and is known for type I collagen peptides. Buyers rate it highly for results but give it lower marks for mixability and accuracy of serving size labeling on the canister.
Any advice on Marine Collagen supplements?r/30PlusSkinCare
Expect to see skin and hair changes with regular use. Plan for dissolving trouble—some batches clump or congealed, so you may find undissolved pieces. The serving size marked on the package may not match what you actually scoop.
Is there a difference in nutritional properties of collagen peptides and marine collagen peptides?r/nutrition
Marine collagen is derived from fish and is the type I peptide form. The main difference buyers notice is how well it mixes, not the nutritional outcome—both deliver visible results for skin and hair.
What are the downsides of this marine collagen?
Dissolving is the biggest complaint—buyers struggle to get it to mix smoothly, and some encounter clumped or congealed pieces. The packaging isn't easy to work with, and the serving size label doesn't always match what you actually get per scoop.
