Marine Collagen Peptides, Are the Beauty Benefits Worth it? A Registered Dietitian Explains
Marine collagen peptides and powders aren’t just a trend. They’re backed by science and have been found to provide benefits for your skin, hair, joints, and more. Read on to learn more and discover what we think are the best marine collagen supplements.
If you’ve been wondering what all the fuss is about marine collagen, you’ve come to the right place.
We’re passionate about collagen. We’ve covered everything from our favorite collagen picks, in one of our most read guides, the best collagen supplements powders and peptides, written by a dietician. We’ve even answered the question: do collagen supplements work on wrinkles and sagging skin? And what about the different collagen types? Is there a best one? And where does your collagen powder really come from? And if you’re vegan we have you covered with our guide to vegan collagen supplements. All of these are important questions you want answers to, so we’ve done the homework.
As more and more research emerges, we’re learning that compared to other types of collagen, marine collagen peptide powders are more bioavailable and friendlier to the environment. And this is all while doing great things for your skin health, joints, and hair—it’s basically the fountain of youth, in powder form. You can enjoy it in delicious and healthy drinks such as our Almond Hot Cocoa With Collagen or Mint Chocolate Shake With Spinach & Collagen Powder (watch the video to see how easy it is to make!). Probably one of the easiest hacks is to add collagen in your coffee in the mornings. https://shop.organicauthority.com/products/just-marine-collagen-sticks?_pos=2&_sid=195d8e6bf&_ss=r
Why are we so passionate about collagen? Because the science doesn’t lie, collagen production starts slowing as early as 18 years old. By age 40, we’re losing collagen at a rate of 1% a year affecting our skin, joints, hair, muscles, gut and more (it’s the largest protein form in the body!).
Be sure to speak to a qualified healthcare professional before consuming any product.

What is Marine Collagen?
Marine collagen is exactly what it sounds like: a source of collagen that comes from pure marine sources. The collagen mostly comes from the skin and scales of various fish and other sea life, like seaweed and sponges. Don’t get grossed out—it doesn’t smell fishy at all, we promise.
But what the heck is collagen to begin with, you say? Collagen is an important protein present in your skin, bones, tendons, intestines, muscles, and other tissues in your body. It’s the most abundant protein in your body, providing structure and helping your body function. Without collagen, everything from your cheeks to your knees would be as dry and inflexible as a piece of chalk. (Like a skeleton… AKA, you’d be dead).
Does Marine Collagen Contain Type I or II Collagen?
There are actually 28 types of collagen in our bodies, each of which plays a different role. Collagen type I is the form we’ll focus on the most in this article, because it’s found in your bones, skin, and connective tissue, and is the dominant form found throughout the body.1 We’ll also look at collagen type II, another form of collagen found in your joints.2
The collagen types don’t matter as much as people think, as they all contain the amino acids we need to build a strong body. When you consume specific collagen types, it does not target specific parts of the body, for example your nails. The collagen is broken down into amino acids that can be absorbed by your body and supports the whole body.
Many marine collagen supplements contain both collagen type I and type II. Since collagen itself is not widely found in food (although you may be able to support your body’s collagen production through food), many people choose to supplement collagen for the benefits, which we’ll go over in the next section.
Your body makes collagen on its own, but supplementing what your body makes with marine sources can be helpful. This is because our bodies produce less and less collagen as we age (one more thing to worry about with each birthday), so using a marine collagen supplement can help your body supply all of the protein it needs to continue supporting your skin, joints, bones, nails, and more. You can’t stop age-related changes (yet), but you might be able to slow time down using supplements like marine collagen peptides.
What’s the Best Way to Take Marine Collagen?
We’ve found that the best way to take marine collagen is in a powder form that you can add to food or liquids. Hydrolyzed marine collagen powders, like our favorite matcha and coffee flavors from Crushed Tonic, can be easily mixed into your preferred foods or drinks for an on-the-go beauty boost. Collagen margarita, anyone? Or double-up the health benefits by adding Dr. Nigma’s Beauty Cocktail Marine Collagen Powder to your morning smoothie or juice — the bright berry flavor pairs perfectly.
To learn more about marine collagen, it’s helpful to look at what marine collagen actually does to understand its potential benefits.
Here’s What Hydrolyzed Collagen Is
Most of the marine collagen supplements you’ll see on the market today are hydrolyzed. This means the collagen has been pre-broken down for you, making it easier for your body to digest, absorb, and use the important nutrients inside.
Do Marine Collagen Peptides Work?
You may see these hydrolyzed collagen supplements described as marine collagen powders or marine collagen peptides on the label. Of course, the product in the container matters even more than the label—remember what they say, beauty is on the inside!
If you’ve checked out our shop, you probably already noticed that we carry our absolute favorite collagen powders, including vegan collagen support for those who stay away from animal products. We believe in these powders and the science that backs them up—marine collagen powders and peptides have been linked to several health and beauty benefits, including for your skin, joints, and nails.
Marine Collagen Benefits
One of the (few) good things to come out of the pandemic was the realization that self-care is imperative. And for many people, self-care involves skin care. As it should! The skincare industry is booming, and much of it is centered around the idea of “beauty from within,” an approach to your skin’s health that involves nutrition and what you put into—and on—your body.3 Although research on marine collagen is still emerging, many of the studies do involve skin care.
Dry, Wrinkled Skin
One such study looked at the effects of oral marine collagen peptides on dry, wrinkled skin.4 After 8 weeks of supplementation with marine collagen peptides, participants were found to have significant increases in skin hydration, with the dermis layer of the skin appearing stronger, denser, and with better bounce back. The study also noted that marine collagen improved the density and structure of the dermis, a layer of the skin deep below the surface. Sounds a bit like a superpower… We’re pretty sure all those Marvel heroes use marine collagen on the daily.
Another human trial using marine collagen peptides had similar positive results. It found that study participants using marine collagen had significant wrinkle reductions of 35% after 12 weeks when compared to the placebo group.5 Researchers also found that those who used the hydrolyzed marine collagen had improved skin elasticity. Another recent 12-week study found that marine collagen specifically reduced wrinkles under the eyes, around the nose and mouth, and on the forehead.6
Joint Health
As if collagen losses in aging skin weren’t enough, you also lose collagen in your joints as the years go by. Less collagen in your joints can contribute to joint pain, stiffness, and lack of mobility. If your bucket list is only getting longer as you get older, you’re going to want to make sure you’re doing everything possible to stay active and mobile for the rest of your long life.
Collagen type II is found in the joints, so it makes sense that various types of hydrolyzed collagen type II (like from chickens) have been found to alleviate joint discomfort in adults.7 Because marine collagen also contains collagen type II, it is thought to be another option for joint pain relief.
The knees are a common place to experience joint discomfort. And if you’re an athlete, you may begin experiencing joint pain from the physical demands long before your body slows down on collagen production. Fortunately, marine collagen has been linked to improvements in joint discomfort in the knees of young adult athletes.
In a study from 2021, young, active adults aged 18 to 30 took marine collagen supplements daily for 12 weeks.8 Both male and female participants found that their knee pain was significantly reduced at the end of the study, affirming that marine collagen peptides can be helpful in this area.
Hair and Nails
Your luscious locks aren’t looking so luscious these days? There’s hope—your hair may benefit from marine collagen peptides.
As a protein, collagen is made up of many amino acids, or protein building blocks. Some of the amino acids found in marine collagen, like glycine and proline, are also found in keratin, the protein that is needed for your hair to grow and remain healthy. The theory is that the amino acids from collagen supplements can be used to make more keratin for your hair.
Even though the jury is still out when it comes to marine collagen benefits for hair, a more definitive benefit has been proved for your claws—er, nails. A small trial involving women with brittle nails found that supplementing with collagen peptides for 6 months led to longer and stronger nails, with less breakage.9
Bone Health
Researchers are continuing to learn new ways that marine collagen may be beneficial for human health.
A recent review reported that marine collagen may be used for wound healing and bone regeneration.10 The review points out that marine collagen peptides have a low molecular weight, which makes them more absorbable in the body, which improves wound healing.
The same review also referenced studies on marine collagen’s ability to aid in bone regeneration.11 Researchers found that marine collagen peptides increase the absorption of calcium and zinc, two nutrients vital to bone health. Rats treated with marine collagen peptides had denser, stronger bones at the end of one study discussed in the review.
Although there haven’t been many marine collagen trials on humans, we can still learn about potential benefits for ourselves from animal and lab studies.
Collagen’s Unique Amino Acid Profile
All collagens, no matter the source, have a unique amino acid profile.12
Marine collagen, bovine collagen, and other collagen sources contain more of the amino acids proline and glycine compared to other amino acid-containing foods and supplements. But even more unique is that collagen, unlike other amino acid supplements, naturally contains hydroxyproline. Hydroxyproline is an amino acid that is almost exclusively found in collagen—only a few other protein sources contain it!
And why should you care about hydroxyproline? Hydroxyproline is especially important because it is used to make collagen stronger.13 The addition of oxygen and hydrogen (also known as a hydroxyl group) to the amino acid proline yields hydroxyproline, the more stable cousin of proline.14 These factors make this amino acid a stand-out component of your collagen powder.
Are Marine Collagen Peptides Better than Bovine Collagen?
While bovine collagen has its own list of potential benefits for your health, marine collagen may be the better option. This is especially true if you’re planning on using marine collagen for beauty purposes.
Marine collagen is mostly made up of type I collagen, the type of collagen found in your skin and other connective tissue.15 And while bovine collagen has some type I collagen, marine sources tend to have more.
Basically, if you want better skin hydration, fewer wrinkles, and increased skin elasticity, then you need type I collagen. And since marine collagen has more type I collagen, it makes it the better choice for your skincare routine.
Marine Collagen is More Bioavailable
Marine collagen gets another point on the scoresheet for bioavailability. Due to its smaller molecular weight compared to bovine collagen, marine collagen is easier for your body to absorb.16 This means more collagen actually enters your body and can then be used where you need it most.
And if sustainability is important to you, then marine collagen is the best choice. The methods of sourcing marine collagen have less of an environmental impact compared to bovine collagen.17 Marine collagen is sourced from parts of the fish that are usually discarded, like the skin, scales, and bones. Using these parts for collagen powders makes better use of fish skins that have already been caught, while also cutting down on waste.18
