Collagen supplements are often taken from seaweed or cowhide. However, some scientists agree that collagen taken from fish might just be the most efficient when it comes to absorption.

Also known as marine collagen, this type of collagen’s main selling point is more than just a typical collagen supplement, but also on it being a more environmentally friendly and sustainable source than most collagen types. The reason is marine collagen is created from parts of fish that are normally discarded or thrown away.

Can Marine Collagen Peptides be as good as it is sustainable? Let’s find out!

Who Makes It?

Marine Collagen Peptides is sold by Vital Proteins. Vital Proteins is a company that has multiple offices in Europe and the United States [1]. They sell many forms of supplements in many forms of medium, but their biggest products are collagen-based.

Marketing Claims Made

The following claims were made about Marine Collagen Peptides:

  • High bioavailability: We checked the background of Marine Collagen Peptides and found that it does have the best bioavailability in all collagen types.
  • Hair, skin, nails, and joint benefits: The benefits of collagen supplementation are similar regardless of source, however, we can argue that Marine Collagen Peptides does a better job when it comes to collagen benefits.

What’s in it?

Now, let’s take a closer look at what’s inside Marine Collagen Peptides:

  • Collagen Peptides from Whitefish: Much like Vital Proteins Collagen Peptides, Marine Collagen Peptides also only has one real ingredient which is sourced from whitefish [2]. The sources matter when it comes to collagen because, in the case of Marine Collagen Peptides, the collagen comes from otherwise to-be-disposed fish parts. In a world where everything must be reusable and sustainable, Marine Collagen Peptides is quite progressive.

Supplement Facts Label

Vital Proteins Marine Collagen Peptides


Dosage is critical when it comes to Marine Collagen Peptides. Unlike some ingredients that you can make do with standardization and concentrates, collagen powder can’t be purified further than what you have after traditional processing. When it comes to supplements that work on skin, hair, and bones, more is almost always better.

On their website, Vital Proteins declare the following amino acid content per serving of Marine Collagen Peptides:

  • Alanine – 239 mg
  • Arginine – 193 mg
  • Aspartic acid – 128 mg
  • Cystine – 1 mg
  • Glutamic acid – 267 mg
  • Glycine – 571 mg
  • Histidine – 18 mg
  • Hydroxyproline – 328 mg
  • Isoleucine – 29 mg
  • Leucine – 57 mg
  • Lysine – 83 mg
  • Methionine – 24 mg
  • Phenylalanine – 41 mg
  • Proline – 202 mg
  • Serine – 68 mg
  • Threonine – 63 mg
  • Tyrosine – 7 mg
  • Valine – 53 mg

While Marine Collagen Peptides does have a much lower amino acid content compared to Vital Proteins original Collagen Peptides, we gotta give them a hand for at least being honest about it and not trying to cover it up.

So, what does collagen do for the body?

  1. Makes your skin healthier: Supplementing collagen can help reduce or slow down the skin aging process [3]. It’s so good, you’d have trouble finding someone taking collagen for anything other than skin benefits.
  2. Reduces joint pains: Some studies show taking collagen supplements not only provide joint pain relief, but also help improve symptoms of osteoarthritis [4]. This is good news for those who are already in their 40s and 50s and make collagen supplementation a natural transition.
  3. Helps preserve muscle: Since collagen is strongly related to protein, taking collagen supplements can lead to better muscle preservation. Studies show supplementation can delay sarcopenia, a condition where our muscles lose mass with age [5].
  4. Heart Healthy: Research demonstrates collagen supplementation’s benefits with regards to Atherosclerosis [6]. This is due to how collagen helps “fix” broken arterial tissue.
  5. Hair and nails: Hair and nails are probably the second most popular reason people take collagen for and with good reason. Our hair and nails are made up of collagen. Thus, supplementing with collagen can lead to healthier growth from the roots [7].


For the most part, collagen supplements, in general, are regarded as safe for consumption. However, do note that this is Marine Collagen Peptides. If you have allergies to fish or can’t stand the smell of powdered fish, you might not be a fan of this one.

We always recommend you speak with your doctor before taking any supplements featured on this site.

How to Take It

If you bought the powder, Vital Proteins recommends taking Marine Collagen Peptides by adding it to smoothies and protein shakes. If you bought the capsule, they recommend you take 7 capsules two times per day with 8 ounces of water.


There shouldn’t be any real taste or flavor since this is in capsule form. However, it’s fish-based and could taste or smell strongly of fish.

Number of Servings

One bottle has about 51 servings. One serving is 7 capsules.

Top Alternative to This Product

NEOCELL Marine Collagen vs Vital Proteins Marine Collagen Peptides

We think the best product to rival Vital Proteins Marine Collagen Peptides is NEOCELL Marine Collagen.

NEOCELL has more to offer than just pure Marine Collagen, though. It has vitamins, minerals, and even hyaluronic acid for extra tissue hydration. The offside is, you’re only getting 2,000 mg, whereas Vital Proteins offers 2,500 mg.

While NEOCELL is only sold in 30-serving bottles, buying two bottles is around $12.00 cheaper than Vital Proteins’ own.

Which one is better? If you want some added perks, NEOCELL might be the better product. For pure Marine Collagen, the decision goes to Vital Protein Marine Collagen.

Customer Feedback

Based on what we found online, customers say it helped them curb their appetite. In the case of powder, it’s easily dissolved. However, some critics point out that they had a skin reaction to it, the bad smell, and even bouts of dizziness and gout.

Bottom Line

Vital Proteins Marine Collagen Peptides is more than just an ordinary fish collagen peptide. It’s a product that sources its one key ingredient from raw materials that would otherwise have been discarded.

It’s pricey and doesn’t have that much when it comes to amino acid content, but the fact that you’re helping the environment in a way could be the deciding factor for you to buy this product.

It still smells like fish, though, so if you hate that smell then you shouldn’t buy anything fish-based.
