Marine Collagen Powder - 7.8 oz

Building a collagen habit shouldn't feel like a chore — it should feel like something you'd do anyway, just with a little more purpose behind it. Vital Proteins Marine Collagen is built for exactly that: a neutral-flavored marine collagen peptides powder that slips into the drink you're already making.

Each scoop delivers 12g of collagen peptides made from a single ingredient — collagen sourced from wild-caught whitefish. Collagen itself is built from 18 amino acids, and this formula supplies 8 of the 9 essential ones, the building blocks your body uses to support skin, hair, nail, and joint health as natural collagen production slows with age.

Because it's derived from fish rather than bovine hide, marine collagen tends to carry a smaller peptide size than land-animal collagen, which is why it dissolves fully in both hot and cold liquids without clouding or gelling — no gritty texture, no fishy taste, just a clear mix-in.

Stir it into your morning coffee, blend it into a smoothie, whisk it into oatmeal, or dissolve it into a mug of tea. It holds up in heat and dissolves cleanly in a hot latte without curdling, and it won't alter the taste of whatever you're mixing it into.

Formulated for pescatarian, paleo, and Whole30 routines: Paleo Friendly, Gluten Free, Dairy Free, Kosher Certified, Non-GMO Project Verified, and made with no artificial sweeteners. With virtually no carbs or sugar per serving, it's also a natural fit for keto and other low-carb lifestyles. Store in a cool, dry place with the lid sealed tightly between scoops to keep the powder free-flowing.

Common Questions

How does marine collagen compare to bovine collagen nutritionally?
Both supply collagen peptides, but the amino acid ratios differ slightly and the molecular size does not. Marine peptides typically run in the 2,000-5,000 dalton range versus 3,000-6,000 daltons for bovine, which is the main reason marine collagen dissolves faster in cold liquid without clumping. Gram for gram, this product delivers 12g of collagen peptides per scoop with roughly 8-10 calories and 0g of fat, carbs, or sugar, comparable to most bovine collagen powders on the market. The real difference isn't nutrient density, it's solubility and a milder taste profile, since fish-derived peptides don't carry the same connective tissue smell that beef hide collagen can have when heated.

What does collagen actually do in the body, and why does it need amino acids from food?
Collagen is the structural protein that makes up roughly 30% of total body protein, forming the scaffolding in skin, cartilage, tendons, and connective tissue. It's built from 18 amino acids, most heavily glycine, proline, and hydroxyproline, three that are scarce in a typical Western diet dominated by muscle meat. Natural collagen synthesis slows by about 1% per year starting in your mid-20s, which is why skin elasticity and joint cushioning gradually decline with age. Supplementing with hydrolyzed collagen peptides supplies these specific amino acids in a pre-broken-down form your body can absorb and use as raw material, rather than having to synthesize them from scratch.

Does this fit keto, paleo, or carnivore diets?
Yes to all three. One scoop has 12g of protein, 0g net carbs, and 0g fat, so it drops into a keto macro count without touching your carb ceiling. It's Paleo Friendly certified because it's a single-ingredient animal protein with no fillers, gums, or added sweeteners, and it's Gluten Free and Dairy Free as well. For carnivore-style eating, marine collagen is one of the few plant-free protein powders that mixes clean into coffee or bone broth without introducing dairy or plant-derived thickeners, making it an easy add for anyone tracking strict animal-based macros.

Can I use this in cooking or baking instead of just drinking it?
Yes, because it's unflavored and fully soluble in both hot and cold liquid, it works in far more than beverages. Stir it into pancake or waffle batter for a protein boost without changing the texture, whisk it into homemade salad dressing or gravy since it dissolves clear with no gel formation at moderate heat, or mix it into ground meat for meatballs or meatloaf where it blends in undetected. It also holds up in baked goods like muffins or protein bars without altering rise or crumb, since it's not a gelling gelatin, it's hydrolyzed peptides that stay liquid rather than setting.

How do I know this is actually wild-caught and not farmed or synthetic?
The product carries a Wild-Caught claim on the label alongside Non-GMO Project Verified certification, which requires third-party verification of sourcing and ingredient traceability, not just a self-declared label. It's also Kosher Certified, which involves an independent certifying agency auditing the sourcing and production process against kosher dietary law, adding another layer of outside verification beyond the manufacturer's own claims. Vital Proteins publishes sourcing information for its collagen lines and has built its brand reputation on ingredient transparency since it's a company whose entire business model is collagen, not a private label added to a broader product catalog.

Why choose marine collagen over bovine if I'm not restricted to fish?
The main practical advantage is solubility: marine peptides mix into cold liquids like iced coffee or smoothies without the slight grit or need for vigorous blending that bovine collagen sometimes requires. It's also the better choice for pescatarians, anyone avoiding beef products for religious or dietary reasons, or people who've noticed a faint aftertaste with bovine collagen in delicate drinks like tea. Amino acid profiles between the two sources are close enough that most people won't notice a functional difference in skin or joint support outcomes, so the choice often comes down to dietary restrictions and how the powder behaves in whatever you're mixing it into.
