9 Best Marine Collagen Powders of 2026 (Fish-Sourced Picks)

A tub labeled “multi-collagen” can contain fish alongside beef, chicken or eggshell ingredients. That is not the same purchase as a fish-only powder. These nine marine collagen powders leave bovine and porcine collagen out of the recipe, with labeled collagen portions ranging from 4.2g to 13g.

Written by Tom Miller, CSCS. Updated: November 2026.

Before buying: Every pick contains fish. Marine collagen is neither vegan nor a complete protein replacement. A fish-sourced recipe also is not a blanket medical clearance for someone avoiding mammalian ingredients because of an allergy; check the complete label and cross-contact information with your clinician.

How We Chose

We compared powders from nine different makers, keeping fish collagen separate from bovine, porcine and mixed-source formulas. Each choice has a specified portion and container size. We prioritized plain recipes, clear collagen amounts, useful serving counts and practical directions. The strawberry option earns its place for a different preparation, not as an extra flavor from a brand already counted.

Our editorial ratings also account for additions, fish-allergen information and the difference between collagen grams and total protein. A larger number of servings can mean a smaller portion, so container count alone does not establish value. We do not give extra points for long lists of collagen types, promises of faster absorption or claims that marine collagen is universally better. For a broader comparison across animal sources, see our collagen peptides guide.

Our Top Picks

Best Overall: Sports Research Marine Collagen

Sports Research Marine Collagen Unflavored 12oz

Best Overall

★★★★☆ 4.3/5

Check current price

A plain fish-collagen powder with 10g collagen and nine grams of protein per scoop, in a 34-serving canister without added flavors or sweeteners.

Pros

• 10g collagen per scoop
• 34 servings
• No added flavors or sweeteners

Cons

• Contains fish
• May clump when added directly to cold liquid

Check Price on Amazon

Sports Research keeps the ingredient list to hydrolyzed marine collagen peptides. One 10g scoop contains 10g collagen, 9g protein and 35 calories. The 340g canister has 34 servings, compared with 18 in the selected Vital Proteins container.

For a cold drink, the label tip is useful: mix into room-temperature liquid first, then add ice. Do not assume the powder will disperse equally well when tipped straight into an iced drink. The directions call for one scoop daily.

Skip this if you avoid fish or want a flavored drink. Check the supplied package if a particular fish species matters to you, because species declarations vary between versions. Nordic Naturals has a strawberry recipe, but less than half as much collagen per labeled portion.

Best Tablespoon-Measured Option: Vital Proteins Marine Collagen

Vital Proteins Marine Collagen Unflavored 7.8oz

Best Tablespoon-Measured Option

★★★★☆ 4.2/5

Check current price

The 7.8-ounce paperboard canister contains cod collagen, with 12g collagen and eleven grams of protein measured as three level tablespoons per serving.

Pros

• 12g cod collagen
• Single-ingredient recipe
• Clear 8-ounce liquid directions

Cons

• About 18 servings
• Three level tablespoons per portion

Check Price on Amazon

Vital Proteins’ current 7.8-ounce paperboard canister specifies three level tablespoons, weighing 12g, in 8 fluid ounces of liquid. That portion contains 12g collagen, 11g protein and 45 calories. Follow the directions on your container rather than an old two-scoop reference.

The label identifies cod. You get 2g more collagen per portion than Sports Research, but only about 18 servings in this 221g container. Compare the cost per full portion before deciding that the smaller package is the cheaper routine.

Skip this if you want a larger serving count or dislike measuring tablespoons. Codeage has 50 scoops at 9g collagen each. Vital Proteins also lists a facility that processes milk and fish, which matters when checking cross-contact restrictions.

Best 50-Serving Canister: Codeage Wild-Caught Marine Collagen

Codeage Wild-Caught Marine Collagen Peptides Unflavored 15.87oz

Best 50-Serving Canister

★★★★☆ 4.2/5

Check current price

A 450g canister contains about fifty nine-gram scoops of plain white-fish collagen, without added flavorings, sweeteners, vitamins or a multi-source collagen blend.

Pros

• About 50 servings
• 9g collagen per scoop
• No added flavors or sweeteners

Cons

• Contains fish
• Exact white-fish species not named

Check Price on Amazon

Codeage uses wild-caught, cold-water white-fish collagen as its single ingredient. One scoop, about 9g, contains 9g collagen and 9g protein, with 35 calories. The directions specify 8-12 ounces of water or another beverage.

The 450g canister lasts about 50 labeled portions. That is more portions than Anthony’s 454g pouch because Anthony’s portion is 13g, not because Codeage contains more powder. At equal container weight, serving size changes the apparent value.

Skip this if you need a named fish species rather than the broader “white fish” description. Nutricost identifies Pacific cod. Codeage also states that collagen lacks tryptophan, so its protein figure should not be treated as equivalent to a complete protein powder.

Best Strawberry Option: Nordic Naturals Nordic Beauty Marine Collagen

Nordic Naturals Nordic Beauty Marine Collagen Strawberry 5.29oz

Best Strawberry Option

★★★★☆ 4.0/5

Check current price

A strawberry-flavored cod-collagen powder combines 4.2g collagen with 45mg vitamin C per two-teaspoon portion, using stevia rather than an unsweetened recipe.

Pros

• 4.2g collagen per portion
• 45mg vitamin C
• Five-ounce liquid directions

Cons

• Contains stevia and flavoring
• Fish with possible shellfish traces

Check Price on Amazon

Nordic Naturals mixes 4.2g hydrolyzed cod collagen with 45mg vitamin C from acerola. The full two-teaspoon portion weighs 5g and contains 4g protein and 20 calories. The 150g jar has 30 servings.

Combine the portion with 5 fluid ounces of hot or cold liquid. Natural flavor, malic acid, stevia and beetroot color make this a different purchase from the plain powders. Its collagen portion is 5.8g smaller than Sports Research’s.

Skip this if you want collagen alone, avoid stevia or need to avoid shellfish cross-contact. The label says it may contain traces of shellfish. Added vitamin C is a recipe choice, not proof that this drink will outperform a plain marine powder.

Best Small Jar: Further Food Unflavored Marine Collagen

Further Food Unflavored Marine Collagen 5.93oz

Best Small Jar

★★★★☆ 4.1/5

Check current price

Further Food's compact unflavored jar contains fourteen twelve-gram collagen portions, with eleven grams of protein per scoop and no added flavors or sweeteners.

Pros

• 12g collagen per scoop
• One ingredient
• Compact 168g jar

Cons

• Only about 14 servings
• Contains fish

Check Price on Amazon

Further Food has the smallest unflavored container here: 168g, or 5.93 ounces. Each 12g scoop contains 12g collagen, 11g protein and 45 calories. The distinction matters when a listing headline rounds everything to “protein.”

You get the same collagen portion as Vital Proteins, with about 14 servings rather than 18. Add one scoop to a drink or recipe and stir thoroughly. The maker suggests shaking the closed jar two or three times before use because the contents settle.

Skip this if you want a full month of daily portions from one jar. Codeage has 50 smaller portions, while It’s Just! has about 47 portions at the same 12g weight. This is the unflavored fish-collagen recipe, not Further Food’s chocolate or bovine products.

Best Plain Pacific Cod Option: Nutricost Marine Collagen

Nutricost Marine Collagen Unflavored 8oz

Best Plain Pacific Cod Option

★★★★☆ 4.1/5

Check current price

Nutricost names wild-caught Pacific cod as the source of its plain ten-gram collagen scoop, with twenty-three servings in the eight-ounce jar.

Pros

• Pacific cod identified
• 10g collagen per scoop
• No other ingredients

Cons

• 23 servings in this size
• Contains fish

Check Price on Amazon

Nutricost identifies wild-caught Pacific cod on the selected jar. Its 10g scoop contains 10g marine collagen and 10g protein, with 40 calories. No other ingredients are listed.

The 8-ounce jar has 23 portions. Sports Research contains the same 10g collagen per portion with 34 servings in its larger canister. Compare the checkout cost per full portion rather than comparing the two container prices directly.

Skip this if you need a larger supply or a flavored recipe. Nordic Naturals is the strawberry option; It’s Just! has a larger unflavored pouch. Buy the unflavored Nutricost jar for these numbers, because the chocolate version has a different recipe and portion.

Best Larger Collagen Portion: Anthony’s Marine Collagen Peptides

Anthony's Marine Collagen Peptides Unflavored 1lb

Best Larger Collagen Portion

★★★★☆ 4.2/5

Check current price

Anthony's one-pound pouch has a thirteen-gram collagen portion measured as two tablespoons, with twelve grams of protein and about thirty-four servings per bag.

Pros

• 13g collagen per labeled portion
• About 34 servings
• One hydrolyzed fish-collagen ingredient

Cons

• Contains fish
• Exact fish species not identified

Check Price on Amazon

Anthony’s has the largest labeled collagen portion here: 13g in two tablespoons, with 12g protein and 50 calories. The one-pound pouch contains about 34 of those portions. It is made from wild-caught fish collagen, with no added flavors or colors.

That is 1g more collagen per portion than It’s Just!, but fewer portions in the smaller bag. The label identifies France as the country of origin and California as the packing location. It does not identify a specific fish species.

Skip this if you require a named species or want the smallest labeled portion. Nutricost names Pacific cod, while Nordic Naturals contains 4.2g collagen. A larger portion is not evidence of better skin or joint results.

Best Large Pouch: It’s Just! Marine Collagen Peptides

It's Just! Marine Collagen Peptides Unflavored 20oz

Best Large Pouch

★★★★☆ 4.1/5

Check current price

A twenty-ounce pouch supplies about forty-seven twelve-gram portions of plain white-fish collagen, measured as one and a half tablespoons rather than a scoop.

Pros

• About 47 servings
• 12g collagen per portion
• Single-ingredient white-fish recipe

Cons

• Tablespoon measurement rather than a scoop direction
• Contains fish; shared-facility allergens

Check Price on Amazon

It’s Just! has the largest selected package: 567g, or 20 ounces. A 1.5-tablespoon portion weighs 12g and contains 11g protein and 45 calories. The maker identifies the single ingredient as hydrolyzed marine collagen from wild-caught whitefish.

The bag has about 47 portions, compared with 14 in Further Food’s small jar at the same 12g portion. That gives you a longer supply, but does not establish a lower cost until you compare the actual checkout prices.

Skip this if you prefer a rigid jar or require strict separation from other allergens. The package identifies a facility that processes other major allergens. Measure the stated tablespoon portion rather than assuming a scoop from another collagen brand is interchangeable.

Another Plain 50-Serving Option: Ancient Bliss Marine Collagen

Ancient Bliss Marine Collagen Peptides Unflavored 15.87oz

Plain 50-Serving Alternative

★★★★☆ 3.9/5

Check current price

Ancient Bliss lists nine grams of white-fish collagen per scoop and fifty servings per tub, without a separate protein amount on its current panel.

Pros

• 9g collagen per scoop
• About 50 servings
• No added flavors or sweeteners

Cons

• No separate protein amount on the panel
• Fish and tree-nut facility warning

Check Price on Amazon

Ancient Bliss lists 9,000mg, or 9g, wild-caught white-fish collagen per scoop. The 450g tub contains about 50 servings. Its panel does not give a separate protein or calorie amount, so do not substitute the collagen number for either.

Its portion and container size match Codeage’s: 9g and 450g. The directions specify one scoop in 8-12 ounces of a beverage. Compare the two at checkout if a plain white-fish powder is what you want; Codeage has the clearer nutrition panel.

Skip this if a stated protein amount is important to your tracking, or you avoid tree-nut cross-contact. The label identifies a facility that processes fish and tree nuts. Do not choose it on promises of superior absorption or a guaranteed visible change.

Comparison Table

Each amount is for the full labeled portion of the selected powder. Collagen grams and protein grams are separate figures, not two amounts to add together.

How to Choose a Marine Collagen Powder

Check that the collagen really is fish-only

“Marine” on the front is not enough when you are avoiding bovine or porcine collagen. Read every collagen source in a mixed formula. These picks use fish collagen, but the species detail varies: Vital Proteins identifies cod, Nutricost specifies Pacific cod, and Codeage uses the broader description “white fish.”

If your restriction is medical, religious or ingredient-specific, check the whole recipe and manufacturing information. A plain fish ingredient list does not automatically certify every religious requirement or rule out cross-contact with mammalian ingredients.

Compare collagen grams at the actual portion

Nordic Naturals has 4.2g collagen in a 5g flavored portion. Codeage has 9g, Sports Research and Nutricost have 10g, and Anthony’s has 13g. A bigger scoop does not establish better results. Nor does the total powder weight tell you the collagen amount when vitamin C, flavoring or other ingredients are present.

Use the labeled portion to compare price per serving. Then, if useful, compare cost per gram of collagen without changing the directions. A 50-serving tub of 9g portions is not directly equivalent to a 34-serving pouch of 13g portions. Measuring spoons also are not interchangeable with another brand’s scoop.

Keep collagen separate from complete protein

Vital Proteins lists 12g collagen but 11g protein. Anthony’s lists 13g collagen and 12g protein. These numbers describe overlapping contents, not extra protein to add on top. Collagen lacks tryptophan and should not replace a varied diet or a complete protein source.

A randomized trial in 22 older women found greater muscle-protein-synthesis responses with whey than with collagen peptides. It was a short study using a different collagen ingredient, not a comparison of these marine powders. For a plant-based protein alternative rather than animal collagen, see our vegan protein powder guide.

Do not buy a guaranteed skin or joint result

A 2025 meta-analysis of 23 skin-aging trials found benefits when all studies were pooled. Its high-quality and non-industry-funded subgroups did not show statistically significant effects. A brand’s claims about wrinkles, hair or joints do not establish that its particular powder will produce those results for you.

Choose the fish source, portion and recipe you want. Do not pay extra solely for a list of collagen types, an absorption multiplier or the assumption that fish collagen must outperform bovine collagen.

Treat the fish warning as a buying decision

The FDA identifies fish and crustacean shellfish as separate major allergens. Every powder here contains fish; Nordic Naturals also warns of possible shellfish traces. “Hydrolyzed” is not a reason to disregard an allergy. Follow your clinician’s avoidance advice, and read the package you receive rather than relying on a brand-wide assumption.

Alternatives and Drawbacks

A mixed-source collagen can be an alternative only if you are comfortable with every animal source. It does not solve the same buying problem when you specifically avoid beef or pork collagen. Capsules and liquids also change the amount and preparation, so compare the full labeled daily portion rather than the package format alone.

Plain powders avoid added flavor, but “unflavored” does not guarantee an undetectable aroma or taste in every drink. Strawberry Nordic Naturals changes the recipe with stevia and flavoring. Pick the format you are likely to use, without treating convenience as proof of a health benefit.

Frequently Asked Questions

Is marine collagen made from fish?

The powders in this guide use fish-derived collagen. Marine collagen can come from fish tissues such as skin or scales, but the exact tissue and species are not always identified on a product’s label. Read the named source and other ingredients. A multi-collagen blend that includes fish may also contain bovine, chicken or egg-derived ingredients.

Is marine collagen better than bovine collagen?

The clearest difference for this purchase is the animal source. Fish collagen suits readers who want to avoid bovine or porcine collagen while still consuming fish. That does not establish universally better absorption or results. Compare the actual portion, additions, allergens and cost. Do not assume the “marine” label proves a particular skin, joint or recovery benefit.

How much marine collagen should I take?

Follow the directions on the exact product and any advice from your healthcare professional. The full portions here range from 4.2g collagen in Nordic Naturals to 13g in Anthony’s. Those are product directions, not a universal treatment dose. Do not multiply scoops just to match another brand’s number, especially with a formula that adds other ingredients.

Can marine collagen replace my protein powder?

Not as a like-for-like complete protein replacement. Collagen lacks the essential amino acid tryptophan, even when the nutrition panel lists protein grams. It can contribute amino acids, but should not displace balanced meals or the protein source you use for your broader nutrition needs. A marine source does not remove that limitation or make collagen a complete protein.

Can I put marine collagen in coffee?

Several selected powders have directions allowing coffee, other beverages or recipes. Measure the named portion and stir thoroughly; Sports Research suggests starting with room-temperature liquid before adding ice for a cold drink. For premixed options, see our collagen coffee guide, but check the animal source because those recipes are not all fish-only.

Is marine collagen suitable for vegans or people with fish allergies?

No. Fish is an animal source, so these products are not vegan. Every selected powder contains fish, and processing it into smaller peptides does not make an allergy warning irrelevant. Fish and shellfish are different allergens; some products also warn of shellfish traces or shared facilities. Use your clinician’s specific avoidance guidance rather than assuming one “marine” label covers every restriction.

Bottom Line

Sports Research is our practical default for 10g collagen per scoop and 34 plain servings. Vital Proteins raises the portion to 12g, Codeage has 50 smaller portions, and Nordic Naturals is the strawberry option with vitamin C. It’s Just! has the largest selected pouch.

Choose by fish source, measured portion and other ingredients, not promises that marine collagen is universally better. Fish allergies and the incomplete-protein limitation still apply. If you prefer a flavored premix, our collagen hot chocolate guide compares that format separately; check the animal source there too.
