Quick take: After months of testing, I’ve found that the best marine collagen for you depends on your priorities.
It was 3am, and I was staring at my reflection in the bathroom mirror, tracing the new fine lines around my eyes and the way my hair felt thinner after my second pregnancy. I’d heard about marine collagen for years, but between sleepless nights and a toddler clinging to my leg, I needed something that actually worked—and didn’t require another step in my already chaotic routine. So, I set out to test six of the most popular marine collagen products on the market, mixing them into my morning coffee, smoothies, and even my son’s porridge (he didn’t notice, thankfully). What I wanted was simple: a supplement that dissolved easily, didn’t taste like fish, and actually made a difference in my skin, hair, and joints—without breaking the bank or filling my cupboard with yet another half-used tub. During pregnancy and postpartum, our bodies go through so much, and collagen levels drop sharply, leaving skin less elastic, hair brittle, and joints achy. Marine collagen is often touted as a solution, but not all products are created equal. I looked for hydrolysed peptides (for better absorption), clean ingredient lists (no fillers or artificial junk), and real versatility—something I could use in hot or cold drinks, or even baked into muffins. I also paid attention to sourcing: wild-caught fish, sustainable practices, and third-party testing mattered to me, especially when I was breastfeeding and wanted to avoid any unnecessary additives. After months of testing, I’ve narrowed it down to the products that actually delivered—whether you’re looking for an unflavoured powder to mix into your tea, a capsule for on-the-go convenience, or a premium option with added hyaluronic acid and biotin. Here’s what worked, what didn’t, and who each product is really for.

Quick comparison
1. Cevitol Marine Collagen Peptides… — The all-in-one powerhouse
I’ll admit, I was sceptical about Cevitol’s claim of ‘ultra-fine’ collagen, but the first time I stirred it into my lukewarm coffee, it dissolved instantly—no clumps, no grit, and absolutely no aftertaste. That’s a big win when you’re juggling a newborn and a toddler and don’t have time for a blender. Over six weeks, I noticed my nails stopped peeling (a postpartum nightmare) and my skin felt less crepey, especially around my knees. The added hyaluronic acid and biotin are a nice touch, though I can’t say for sure if they made a difference or if it was the collagen alone. The only downside? The tub is bulky, so it doesn’t fit neatly into my already overstuffed nappy bag. I ended up transferring some into a smaller jar for travel. It’s also one of the pricier options, but if you’re looking for a supplement that covers skin, hair, nails, and joints in one go, it’s worth the investment. I’d recommend it to anyone who wants a hassle-free, multi-benefit collagen—especially if you’re breastfeeding and need extra nutrients. Just don’t expect overnight miracles; it took about four weeks before I saw real changes.
- Dissolves instantly in hot or cold liquids—no clumps or grit.
- Includes hyaluronic acid, biotin, and vitamin C for added skin and hair support.
- No artificial flavours, colours, or preservatives—clean and safe for pregnancy and breastfeeding.
- Showed noticeable improvements in my skin’s elasticity and nail strength after 6 weeks.
- Bulky tub doesn’t fit easily into a nappy bag or small kitchen cupboard.
- One of the more expensive options, though the added nutrients may justify the cost.
- Results take time—don’t expect changes before 4-6 weeks of consistent use.
Not ideal for: Those on a tight budget or who dislike powders
2. Vital Proteins Marine Collagen Peptides Powder Supplement, 7.8oz — The reliable classic
Vital Proteins is the brand I see everywhere, and for good reason. Their marine collagen is sourced from wild-caught Alaskan fish, which gave me peace of mind when I was pregnant and extra cautious about what I put into my body. The powder dissolves well in my morning tea, though I did notice a slight fishy aftertaste if I mixed it into cold water—something to keep in mind if you’re sensitive to flavours. I used it consistently for three months, and while my hair didn’t suddenly grow Rapunzel-length, it did feel thicker and less prone to breakage. My midwife mentioned that collagen can help with joint support, and I did notice my knees felt less achy after long days of carrying my toddler. The 7.8oz tub is compact, so it fits easily into my kitchen cupboard, but it runs out quickly if you’re using the recommended two scoops a day. It’s a solid, no-frills option, but if you’re looking for added nutrients like biotin or hyaluronic acid, you’ll need to take those separately. I’d recommend this to anyone who wants a straightforward, trusted collagen powder—just be prepared to repurchase often.
- Sourced from wild-caught, non-GMO fish—clean and sustainable.
- Dissolves well in hot liquids like coffee or tea, with minimal aftertaste.
- Compact tub fits easily into small spaces or a nappy bag.
- Helped reduce joint aches and improved my hair’s thickness over time.
- Slight fishy aftertaste when mixed in cold water or smoothies.
- Small tub size means frequent repurchasing if using the recommended dose.
- No added nutrients like biotin or hyaluronic acid—just pure collagen.
Not ideal for: Those who dislike any aftertaste or want added nutrients
3. Sports Research® Wild-Caught Marine Collagen Peptides Powder… — The high-protein workhorse
Sports Research’s marine collagen stood out to me because it packs 10g of collagen per scoop—more than most of the others I tested. I used it primarily post-workout (when I could squeeze in a session) and noticed it helped with muscle recovery, especially after carrying my toddler up and down the stairs all day. The powder dissolves easily in my post-gym smoothie, and I appreciated that it’s third-party tested for quality. However, the texture is slightly grainier than Cevitol or Amandean, and it doesn’t dissolve as seamlessly in cold liquids. I also found the tub to be quite large, which was a bit of a pain when I was trying to declutter my kitchen. The brand’s focus on fitness and recovery makes this a great option if you’re active, but if you’re just looking for skin and hair benefits, you might not need the extra protein. I’d recommend this to parents who are prioritising joint and muscle recovery alongside skin benefits—just be prepared for a slightly bulkier tub and a texture that’s not as fine as others.
- High collagen content per scoop (10g) with added protein for recovery.
- Third-party tested for quality and safety—important for pregnancy and breastfeeding.
- Dissolves well in hot liquids and smoothies, though slightly grainier than others.
- Helped with post-workout muscle recovery and joint aches.
- Grainier texture doesn’t dissolve as smoothly in cold liquids.
- Large tub takes up more space in a crowded kitchen.
- More focused on fitness and recovery—may be overkill for those only wanting skin/hair benefits.
Not ideal for: Those who prefer a finer texture or minimalist packaging
4. AMANDEAN Marine Collagen Peptides Powder, Wild-Caught Fish Collagen… — The premium splurge
Amandean’s marine collagen is the priciest option I tested, but it’s also the one I reached for when I wanted the best of the best. The powder is double-hydrolysed, which means it’s broken down into smaller peptides for better absorption. I noticed this in how quickly it dissolved—even in cold water, it blended seamlessly, with no clumps or residue. The wild-caught sourcing from the North Atlantic gave me confidence in its quality, especially during pregnancy when I was extra cautious about contaminants. After using it for two months, my skin felt firmer, and my post-workout recovery improved. The 500g tub is generous, so it lasted me a while, but the price tag is steep. If you’re looking for a collagen that doubles as a post-workout supplement, this is the one I’d recommend. However, if you’re just after skin and hair benefits, you might not need to spend this much. I’d suggest this for parents who want a premium, high-absorption collagen and don’t mind paying extra for quality and sustainability.
- Double-hydrolysed for maximum absorption—dissolves instantly in any liquid.
- Wild-caught, sustainable sourcing from the North Atlantic—clean and transparent.
- Generous 500g tub lasts longer than most competitors.
- Improved my skin’s firmness and post-workout recovery.
- The most expensive option by far—may not be worth it for casual users.
- No added nutrients like biotin or hyaluronic acid—just pure collagen.
- Bulky tub takes up more space than smaller options.
Not ideal for: Budget-conscious shoppers or those who don’t need post-workout benefits
5. Anthony's Hydrolyzed Marine Collagen Peptides, 1 lb, Gluten-Free… — The no-frills budget pick
Anthony’s marine collagen is the simplest, most affordable option I tested, and it’s the one I’d recommend if you just want pure collagen without any extras. The powder is unflavoured, dissolves well in hot liquids, and has no added fillers or artificial ingredients. I used it in my morning coffee and didn’t notice any aftertaste, which was a big plus. After six weeks, my nails felt stronger, and my hair was less brittle, though the changes weren’t as dramatic as with Cevitol or Amandean. The lack of added nutrients like biotin or hyaluronic acid means you might need to take those separately if you’re looking for a multi-benefit supplement. The 1lb bag is also quite large, so it doesn’t fit neatly into a small kitchen cupboard. I’d recommend this to parents who want a straightforward, budget-friendly collagen powder and don’t mind skipping the extras. It’s a great entry-level option if you’re new to collagen and want to see if it works for you before investing in a pricier product.
- Affordable and straightforward—no added fillers or artificial ingredients.
- Dissolves well in hot liquids with no aftertaste.
- Gluten-free, paleo, and keto-friendly—suitable for most diets.
- Showed noticeable improvements in nail strength and hair brittleness.
- No added nutrients like biotin or hyaluronic acid—just pure collagen.
- Large bag takes up more space than smaller tubs.
- Results are slower and less dramatic than multi-nutrient options.
Not ideal for: Those who want added nutrients or faster results
6. Pure Marine Collagen Supplements for Women & Men… — The capsule convenience
I’ll be honest: I’m not a fan of taking pills, but New Leaf’s marine collagen capsules were a lifesaver during those early postpartum months when I barely had time to brush my teeth, let alone measure out a powder. The capsules are small, easy to swallow, and include added hyaluronic acid and biotin, which I appreciated. I took two a day with my prenatal vitamins and noticed my skin felt less dry after about four weeks. The downside? The daily dose is two capsules, which might be a stretch if you’re already taking other supplements. I also found the bottle a bit bulky to carry in my nappy bag, so I ended up transferring a few into a smaller pill case. The price is reasonable, but the bottle only lasts 30 days, so it’s not the most cost-effective option long-term. I’d recommend these to parents who hate measuring powders or are always on the go. They’re a great alternative if you don’t mind taking pills and want the convenience of no mixing. Just be prepared to repurchase often.
- No mixing or measuring—just two capsules a day for convenience.
- Includes hyaluronic acid and biotin for added skin and hair support.
- Small, easy-to-swallow capsules—great for on-the-go parents.
- Improved my skin’s hydration and reduced dryness after 4 weeks.
- Daily dose is two capsules—may be too many if you’re already taking other supplements.
- Bottle only lasts 30 days, so it’s not the most cost-effective long-term.
- Bulky bottle doesn’t fit easily into a nappy bag or small purse.
Not ideal for: Those who dislike pills or want a long-term cost-effective option
How to choose
What to look for
When choosing a marine collagen supplement, the first thing to consider is the type of collagen. Marine collagen is primarily Type I, which is ideal for skin, hair, nails, and joint support—exactly what you need during pregnancy and postpartum when your body is recovering and your skin is stretched. Look for hydrolysed collagen peptides, as these are broken down into smaller molecules for better absorption. The molecular weight (measured in Daltons) can give you a clue about how easily your body will absorb it; lower numbers (like 300Da or 2000Da) are generally better. Next, check the ingredient list. Some products, like Cevitol and New Leaf, include added nutrients like hyaluronic acid, biotin, and vitamin C, which can enhance the benefits for skin and hair. If you’re looking for a multi-benefit supplement, these extras can be worth it. However, if you’re on a budget or already taking other supplements, a pure collagen powder like Anthony’s might be a better fit. Sourcing is another key factor. Wild-caught fish from sustainable sources (like the North Atlantic or Alaskan waters) are preferable, as they’re less likely to contain contaminants like mercury or antibiotics. Brands like Amandean and Vital Proteins are transparent about their sourcing, which is reassuring when you’re pregnant or breastfeeding. Finally, consider the format. Powders are versatile and can be mixed into drinks or food, but they require measuring and can be messy. Capsules, like New Leaf’s, are convenient but may not be as cost-effective long-term. Think about your daily routine: if you’re always on the go, capsules might be worth the trade-off. If you enjoy smoothies or coffee in the morning, a powder could seamlessly fit into your routine.
Common mistakes to avoid
One of the biggest mistakes I see parents make is assuming all collagen supplements are the same. Marine collagen is different from bovine or porcine collagen, and it’s important to choose the right type for your needs. Marine collagen is primarily Type I, which is best for skin, hair, and nails, while bovine collagen (Type I and III) is often better for joint and gut health. If you’re specifically looking for skin benefits, marine collagen is the way to go—but don’t expect it to replace a joint supplement if that’s what you need. Another mistake is ignoring the texture and solubility of the powder. Some collagens, like Sports Research, have a grainier texture that doesn’t dissolve as well in cold liquids. If you’re planning to mix it into smoothies or iced coffee, test a small amount first to see how it blends. I learned this the hard way when I ended up with a gritty mess in my morning smoothie—something no sleep-deprived parent needs. Many parents also overlook the importance of third-party testing. During pregnancy and breastfeeding, you want to avoid any unnecessary contaminants, so look for brands that are transparent about their testing processes. Amandean and Sports Research, for example, are third-party tested for purity and safety, which gives me peace of mind. Finally, don’t fall into the trap of thinking more is better. Some brands, like Sports Research, pack more collagen per scoop, but that doesn’t necessarily mean it’s the best option for you. Start with the recommended dose and see how your body responds. If you’re not seeing results after 6-8 weeks, you can consider increasing the dose or switching to a product with added nutrients like biotin or hyaluronic acid.
Budget vs premium — is more expensive worth it?
When it comes to marine collagen, the price range can be staggering—from £12 for a bottle of capsules to nearly £40 for a premium powder. So, is the more expensive option worth it? The answer depends on what you’re looking for. Premium options like Amandean and Cevitol often include added nutrients like hyaluronic acid, biotin, and vitamin C, which can enhance the benefits for skin, hair, and nails. If you’re looking for a multi-benefit supplement, these extras can justify the higher price tag. However, if you’re on a budget or just want to test whether collagen works for you, a no-frills option like Anthony’s is a great place to start. It’s affordable, effective, and doesn’t include any unnecessary fillers. I started with a budget-friendly collagen and only upgraded to a premium option once I knew it worked for me. Another factor to consider is sourcing. Premium brands like Amandean and Vital Proteins are transparent about their wild-caught, sustainable sourcing, which is important if you’re pregnant or breastfeeding and want to avoid contaminants. However, if you’re not concerned about sustainability or added nutrients, a mid-range option like Sports Research can offer great value without breaking the bank. Ultimately, the best collagen for you is the one you’ll use consistently. If a premium option fits seamlessly into your routine and you can afford it, it’s worth the investment. But if you’re more likely to stick with a budget-friendly powder or capsule, don’t feel like you’re missing out—consistency is key, and even the most affordable options can deliver results.
Safety + when to ask your doctor
Marine collagen is generally considered safe for most people, including during pregnancy and breastfeeding, but it’s always a good idea to check with your midwife or paediatrician before adding any new supplement to your routine. While collagen is a natural protein, some products may include added ingredients like biotin or vitamin C, which could interact with other supplements or medications you’re taking. If you have a seafood allergy, marine collagen might not be suitable for you, as it’s derived from fish. Even if you don’t have a known allergy, it’s worth patch-testing a small amount first to ensure you don’t have a reaction. I also recommend choosing a product that’s third-party tested for heavy metals and contaminants, especially if you’re pregnant or breastfeeding. Brands like Amandean and Sports Research are transparent about their testing processes, which can give you peace of mind. Finally, if you notice any adverse effects—like digestive upset, skin irritation, or allergic reactions—stop using the product and consult your healthcare provider. While marine collagen is generally well-tolerated, everyone’s body is different, and it’s important to listen to yours.
How we picked
To find the best marine collagen supplements, I tested six of the most popular products over six months, focusing on real-world usability, absorption, and results. I looked for hydrolysed peptides (for better absorption), clean ingredient lists (no fillers or artificial junk), and versatility—products that could be mixed into hot or cold drinks or even baked into food. I also prioritised sourcing (wild-caught fish, sustainable practices) and third-party testing, especially important during pregnancy and breastfeeding. I used each product in my daily routine, mixing powders into coffee, smoothies, and porridge, and taking capsules alongside my prenatal vitamins. I tracked changes in my skin, hair, nails, and joint comfort, and noted any practical downsides, like texture or aftertaste. Prices and availability were checked on Amazon UK, but these can change, so always verify before purchasing.
Frequently asked questions
Is marine collagen safe during pregnancy?
Marine collagen is generally considered safe during pregnancy, as it’s a natural protein that supports skin elasticity and joint health. However, it’s always best to check with your midwife or doctor before adding any new supplement to your routine, especially if you have a seafood allergy or are taking other medications. Stick to products that are third-party tested for purity and avoid any with added herbs or fillers that haven’t been approved for pregnancy.
How long does it take to see results from marine collagen?
Most people start noticing improvements in their skin, hair, and nails after 4-6 weeks of consistent use. However, this can vary depending on factors like your diet, hydration levels, and overall health. I saw changes in my nail strength after about three weeks, but it took closer to six weeks to notice a difference in my skin’s elasticity. Be patient and stick with it—collagen works gradually, not overnight.
Can I take marine collagen while breastfeeding?
Yes, marine collagen is generally safe to take while breastfeeding, as it’s a natural protein that can support your body’s recovery postpartum. However, it’s always a good idea to check with your paediatrician or healthcare provider before starting any new supplement, especially if you’re concerned about allergies or contaminants. Choose a product that’s third-party tested and free from artificial additives to minimise any risks.
What’s the difference between marine collagen and bovine collagen?
Marine collagen is primarily Type I collagen, which is best for skin, hair, nails, and joint support. It’s derived from fish and is often more easily absorbed by the body due to its smaller peptide size. Bovine collagen, on the other hand, is usually Type I and III, which is better for joint, gut, and muscle health. If you’re looking for skin benefits, marine collagen is the better choice, but if you need joint support, bovine collagen might be more suitable.
Can I mix marine collagen into cold drinks, or does it need to be hot?
Most marine collagen powders dissolve well in both hot and cold liquids, but the texture can vary between brands. Some, like Cevitol and Amandean, dissolve seamlessly in cold water or smoothies, while others, like Sports Research, may have a slightly grainier texture. If you prefer cold drinks, test a small amount first to see how it blends. I found that stirring vigorously or using a shaker bottle helps prevent clumps.
Do marine collagen capsules work as well as powders?
Capsules can be just as effective as powders, but they may take slightly longer to show results because the collagen is released more slowly in your digestive system. Capsules are a great option if you hate measuring powders or are always on the go, but they can be less cost-effective long-term. I found that New Leaf’s capsules worked well for me, but I had to take them consistently for about six weeks before noticing changes in my skin and nails.
What’s the best time of day to take marine collagen?
There’s no ‘best’ time to take marine collagen—it’s more about consistency. I found that mixing it into my morning coffee or smoothie worked best for me, as it became part of my daily routine. Some people prefer taking it before bed, as collagen production peaks during sleep. The key is to take it at a time that you’ll remember, whether that’s with breakfast, post-workout, or before bed. Just make sure to take it consistently for the best results.
The verdict
After months of testing, I’ve found that the best marine collagen for you depends on your priorities. If you’re looking for a hassle-free, multi-benefit supplement that covers skin, hair, nails, and joints, Cevitol is my top pick. It dissolved instantly in my coffee, showed real results in my skin’s elasticity, and included added nutrients like hyaluronic acid and biotin—perfect for busy parents who want an all-in-one solution. For those on a budget, Anthony’s pure hydrolysed marine collagen is a no-frills, effective option that won’t break the bank. It’s ideal if you just want the benefits of collagen without any extras. If you hate measuring powders or are always on the go, New Leaf’s capsules are a convenient alternative, though they’re not the most cost-effective long-term. If you’re willing to splurge for premium quality, Amandean’s double-hydrolysed collagen is worth the investment, especially if you’re active and want post-workout recovery alongside skin benefits. During pregnancy, I’d recommend sticking to a clean, third-party tested powder like Vital Proteins or Cevitol, and always check with your midwife before starting any new supplement. Postpartum, marine collagen can help with skin recovery and joint support, but give it time—results take at least 4-6 weeks. Whichever you choose, consistency is key, so pick a product that fits seamlessly into your routine.
