I’ve written earlier than in regards to the well being advantages of collagen and the way it’s the commonest protein in our our bodies. I attempt to devour collagen powder frequently as a result of we all know it boosts our physique’s inside collagen manufacturing. This protein is particularly essential for us girls due to its anti-aging results on pores and skin, ligaments, and joints. After all, we want to have the ability to sustain with our energetic kiddos! 

You can consider collagen because the glue that helps maintain your physique collectively. Unfortunately, we make much less of it as we age. When collagen will get depleted, you possibly can find yourself with wrinkles, brittle hair, joint ache, and digestive points. Since nobody has time for these, supplementing with collagen could be useful at any age.

If you didn’t realize it was an possibility, marine collagen has some distinctive benefits, which I’ll cowl beneath. It’s additionally a wonderful possibility for pescatarians, these with sensitivities to poultry or beef, and people who keep away from cow and pork merchandise for spiritual causes. 

What Is Marine Collagen?

This powdered complement comes from all types of sea life. Collagen protein can come from seafood or fish pores and skin, scales, bones, or cartilage, and it may even come from the umbrella of a jellyfish! 

You’ll see it marketed as marine collagen peptides as a result of it goes by a course of referred to as hydrolysis, which makes it dissolve higher into different meals. It’s straightforward so as to add this constructing block to your favourite drinks (extra on that later). 

The physique has three major sorts of collagen. Of the three major sorts of cartilage, marine accommodates largely kind I, the identical kind people have essentially the most of. 

Marine Collagen vs. Bovine Collagen

Unless in any other case marketed, plain collagen sometimes comes from grass-fed, pasture-raised cows. Bovine collagen primarily has the amino acids glycine and proline and accommodates each kind I and kind III collagen. 

One of the principle benefits of marine collagen vs. bovine is a decrease danger for infections. An instance could be mad cow illness. Obviously, that danger continues to be fairly low in your typical grass-fed beef collagen.

Another benefit is for many who are attempting to lower their animal merchandise like crimson meat. We know that fish is more healthy, so it is sensible that marine collagen feels to be a greater supply of collagen in contrast with cow or pig pores and skin and bones.

Multiple research have found that marine collagen performs higher than bovine for numerous sorts of tissue regeneration. A 2017 research on connective tissue discovered that marine collagen outperformed bovine. A 2021 comparability between bovine and cod collagen discovered that marine collagen helped pores and skin heal higher than bovine.

Marine Collagen vs. Fish Collagen

Fish collagen is a sort of marine collagen. Sometimes, the names are used interchangeably however they aren’t the identical. Common sources of marine collagen vary from starfish to jellyfish to squid. On the opposite hand, fish collagen comes from cod, mackerel, tuna, salmon, and others. 

Each sort of marine life provides a distinct mixture of each important and non-essential amino acids. They’re all excessive in proline, glycine, and hydroxyproline, that are nice for pores and skin well being and connective tissues. The further hydroxyproline is exclusive to marine collagen, which can be what makes it so nice for skincare.

Health Benefits of Marine Collagen 

In specific, marine collagen is extra bioavailable than different varieties. That means it’s simpler for the physique to soak up and use. Some assume this could be as a result of marine collagen has smaller particles. The smaller dimension helps it go by the intestinal barrier extra simply, delivering these antioxidants and amino acids to the bloodstream, and finally to the place we want them most—whether or not that’s plumping up growing old pores and skin or therapeutic an damage. 

A 2020 research discovered that marine collagen accelerated wound therapeutic after C-sections. I want I had taken it after my C-section to cut back scarring. 

I ought to observe that your physique wants vitamin C to make use of collagen. Make positive you’re getting sufficient of it from meals, or discuss to your well being practitioner a couple of complement in case your ranges are low. 

Environmental Benefits 

Anytime I can do one thing to assist the setting, I attempt to. I need my youngsters and future generations to get pleasure from our lovely planet. 

Marine collagen could also be extra sustainable than different types of collagen. Fish harvesting firms normally discard the bones, pores and skin, head, and scales. These “waste products” are good for making marine collagen. 

I believe it’s superior to show what was beforehand waste right into a wellness-boosting complement. The much less trash we make, the higher. This additionally helps hold the value of it low because it’s repurposing what would in any other case be thrown away.


Don’t take this sort of collagen if in case you have a fish or shellfish allergy or sensitivity. You should still react and discover that you simply’re doing extra hurt than good with this complement. As at all times, discuss to your physician about it. 

Even although there aren’t any identified unwanted effects, consultants disagree on the protection of marine collagen throughout being pregnant, so I don’t advocate it. Hopefully, extra analysis will come out and show it secure. 

Why I Use It

In addition to the hydroxyproline, one of many largest attracts to utilizing marine and fish collagen is that it helps me rotate my dietary supplements (stopping sensitivities from utilizing the identical substances day after day) however nonetheless offers me the advantages of collagen nearly each day. It could assist with pores and skin elasticity and hydration—who doesn’t need good pores and skin and wholesome hair? 

Sometimes once I purchase shrimp, I’ll devein it myself and use the shells to make fish broth. (See my recipe for bone broth right here.) Since doing that is somewhat time-intensive, I don’t do it typically. It’s straightforward to only throw the hydrolyzed powder into a few of my common recipes. As a mother, this wholesome shortcut is a giant win in my guide. 

What Does It Taste Like?

Thankfully, it doesn’t scent or style fishy. It’s truly odorless and largely flavorless. If you eat a spoonful of it plain, you would possibly get a touch of fish, however should you add it to a smoothie or sizzling drink, you don’t get any fishy taste profiles.

How to Use Marine Collagen Peptides 

The good factor about marine collagen is that it’s so versatile. It works properly in each cold and hot drinks. It’s fast and straightforward to combine collagen peptides into my favourite drinks.

I like so as to add a scoop or two of it to those chilly recipes (since gelatin doesn’t combine in properly): 

  • Orange Creamsicle Smoothie – Marine collagen mixes properly into this summer time breakfast or snack that my youngsters love
  • Iced Turmeric Lemonade – Combine the antioxidants and anti inflammatory advantages of turmeric with collagen on this refreshing drink that’s additionally wealthy in vitamin C

  • Cold Brew Coffee – I prefer to make this one the evening earlier than for busy mornings 

I prefer to dump it into these sizzling drinks too:

One of my mates provides collagen to her youngsters’ oatmeal to sneak in a protein increase. Here are extra concepts on how I exploit collagen hydrolysate

Where to Buy Marine Collagen Supplements

Just as you’d search for grass-fed bovine collagen, if you wish to purchase a marine collagen complement, search for wild-caught. Factory farms sometimes deal with fish with antibiotics and different unsavory chemical compounds, lots of that are contaminated by poisonous or heavy metals. Wild-caught fish are much less prone to have contaminants like heavy metals. In case you’re questioning why, listed here are the issues with factory-farmed fish.

You’ll additionally wish to ensure that it’s non-GMO. When catching fish within the wild, you possibly can’t certify them as natural. So, though I choose merchandise with the natural certification, it’s not attainable with this complement. 

And as at all times, verify the label to ensure that there aren’t any hidden fillers or components. Most will promote being gluten-free however at all times verify the bottom. 

My favourite model of marine collagen is Vital Proteins as a result of they provide each an unflavored marine collagen powder and a capsule kind. Use no matter is handy for you. Vital Proteins powders are constructed from the scales of contemporary, Non-GMO Project Verified, wild-caught whitefish off the coast of Alaska.
